Remote sensing surveys, underpinned by archaeological studies, show that charcoal was gained around Cottbus from several thousand charcoal kilns which had internal diameters up to 20 m. For the study site with 35 km2 area, the until now prospected total ground area below the charcoal kilns which was potentially affected by the pyrolysis is about 0,5 km2. Historic data indicates that the pyrolysis in the charcoal kiln took up to several weeks, for the kilns with a diameter of 20 m about 20 days. To characterize the depth of thermal alteration of soils below the kiln our current focus is on the differentiation of the iron hydroxides by small-scale vertical analysis of soil profiles.

This review focuses on anthropo-geomorphic factors and processes associated with small-scale opencast mining (SSOM), a form of A&SM in which near-surface ores are extracted by removing relatively thin covers of soil, bedrock or sediments. Being widespread and commonly conducted without proper planning and beyond the control of local authorities, this form of mining has potentially large impacts on landforms and landscape dynamics, often resulting in drastic consequences for the local environment and agriculture. SSOM should be regarded as a component of anthropogenic geomorphology because it involves the role of humans in creating landforms and modifying the operation of natural geomorphological processes, such as weathering, erosion, transport and deposition. By initiating new and modifying natural geomorphic processes, SSOM causes and/or accelerates geomorphic processes, resulting in various forms of land degradation. While the direct geomorphic impact of SSOM is in general easily discernible and leads to characteristic features, such as excavated pits and overburden spoil heaps, many secondary impacts are attributed to geomorphic processes triggered in the wake of the primary mining-induced landscape alterations. The magnitude of such secondary implications may well extend beyond the actual mining areas, but these effects have not been thoroughly addressed in the research so far. This review summarizes the known studies on the geomorphic impacts of SSOM operations and highlights common geomorphic processes and landforms associated with this type of anthropogenic activity, thus establishing a starting point for further in-depth research.

ED - Kleber, Arno ED - Terhorst, Birgit T1 - Subdued Mountains of Central Europe T2 - Mid-Latitude Slope Deposits (Cover Beds) N2 - Slope deposits, which veil entire slopes or large parts of them in a rather uniform manner (cover beds), are ubiquitous in the subdued mountains of Central Europe. Here we provide an overview of the current state of knowledge on these deposits. The Central European cover beds are divided into (1) the upper layer that is ubiquitously distributed and displays a relatively constant thickness; (2) the intermediate layer the distribution of which is mainly restricted to flat relief, to slope depressions, and to lee-ward facing slopes; and (3) the basal layer, which is rather widespread again. Both the upper and intermediate layer contain intermixed loess, whereas the basal layer is free of loess and typically has a high bulk density. Aside from the loess content, the composition of the layers differs, reflecting varying portions of crushed and chemically weathered rock allocated from up-slope. This causes notable diversity depending on bedrock and, thus, induces remarkable regional differences. Cover beds were mainly formed by periglacial gelifluction. The upper layer formed in the Late Glacial possibly during several short episodes of activity. In contrast, the underlying layers may be diachronous; nevertheless, they display recurring vertical sequences. This is probably due to the fact that loess-free layers usually could not deposit as long as there was loess in the environs, which may have been inherited from older deposits. Thus, the last phase of surface wash, during which older loess was removed, determines the age of the lower layers.

A1 - Maurer, Thomas A1 - Raab, Thomas T1 - Evolution of hydro-geomorphic connectivity in an experimental catchment T2 - American Geophysical Union, Fall Meeting San Franisco, USA, 2014 N2 - During initial phases of landform evolution, the surface of sediment bodies is commonly not yet equilibrated with the environmental conditions and is thus liable to rapid changes by accelerated geomorphic activity. Hydro-geomorphic processes acting during these early development phases often lead to the emergence of surface structures that constitute the boundary conditions for further ecosystem development, and of linear erosion features that act as pathways for water, solute and sediment transport, and thus can increase the system's connectivity. Studies on initial landform evolution are often limited to relatively small-scale experiments or rely on modeling exercises. Larger-scale experiments can be carried out in constructed hydrological catchments with well-known and documented initial conditions. The central aim of this work was to describe the hydro-geomorphic surface structure evolution during the initial years of ecosystem development, its dependence on initial and boundary conditions; and on its relations to hydro-geomorphic connectivity. The data are from the 6-ha, constructed hydrological catchment 'Hühnerwasser'. Hydro-geomorphic development was quantified using a combined analysis of digital elevation models and aerial photographs. Empirical results were compared with those obtained with a numerical landscape evolution model. Phases of rill network growth, contraction and stabilization could be characterized. Results show influences of initial morphology, precipitation characteristics, and developing structure-process-interactions on rill network geometry and connectivity increase in the catchment. The results suggest that phases of hydro-geomorphic surface structure evolution can be related to the spatial organization of surface flow patterns during initial phases of landform development.

T2 - Environmental Sciences Europe N2 - Background The decision of the German federal government to cease lignite mining until 2038 or—if possible— already earlier until 2030, will cause manifold transition processes in the remaining lignite mining districts of Germany. The two largest districts are located in geographically opposite regions: The Rhineland in the western part and Lusatia in the east of Germany. As particularly these two mining districts will experience severe changes in their socioeconomic as well environmental conditions, the federal government has adopted comprehensive economic support measures. However, the environmental changes will also cause altered ecosystem functions and services to be provided by the future post-mining landscapes. Results In this paper, the two main lignite-producing regions of Germany are compared with regard to their natural and cultural settings. The economic situation and its history are reflected and differences are outlined. Part of the disparities in the cultural development can be explained by very different natural conditions, especially edaphic factors and climatic situation. Because of dissimilar geological settings, different mining technologies were developed and are in use in the two regions with distinct effects on the resulting post-mining landscapes. Conclusion The long-standing and manifold lignite mining activities have radically restructured the landscapes in Lusatia and the Rhineland. With the ongoing decline of the mining industry and its complete cessation, presumably within the next decade, both regions will alter their faces significantly. These changes offer both challenges but also opportunities with respect to the post-mining landscapes and their ecosystem services they are going to provide. The prerequisites for a positive socioeconomic development and for sustainable land-use concepts that also consider ecological aspects are different for both regions. However, or especially because of these differences, the knowledge exchange and experience transfer between both mining regions are pivotal for the success of this extensive transformation process.

The two largest lignite mining areas are located in geographically different regions: Rhineland in the west and Lusatia in the east. As the socio-economic and environmental conditions in these two mining areas are set to change dramatically, the German government has adopted extensive economic support measures. However, the environmental changes will also lead to changes in the ecosystem functions and services provided by the future post-mining landscapes. Gerwin et al. (2023) compare the two main lignite producing regions of Germany in terms of their natural and cultural environments. The economic situation and its history are reflected and differences are outlined. Part of the differences in cultural development can be explained by the natural conditions, especially the edaphic factors and the climatic situation. Because of the specific geological settings, tailored mining technologies were developed and used in the two regions, with different effects on the resulting post-mining landscapes. We conclude that the landscapes of Lusatia and the Rhineland have been radically restructured by the long and varied history of lignite mining. Both regions will change significantly as the mining industry continues to decline and is expected to cease altogether within the next decade. These changes in the post-mining landscapes and the ecosystem services will provide both challenges and opportunities. The preconditions for positive socio-economic development and for sustainable land use concepts that also consider ecological aspects are different for the two regions. The exchange of knowledge and experience between the two mining regions is crucial to the success of this major transformation process, despite, or perhaps because of, these differences.

T1 - Biological topsoil crusts at early successional stages on Quaternary substrates dumped by mining in Brandenburg, NE Germany T2 - Geomorphologie: relief, processus, environnement N2 - The influence of biological soil crusts in natural ecosystems on structures and processes is well investigated. However, in South-Brandenburg (Germany), it is possible to study the development of biological soil crusts (BSC) during initial ecosystem genesis on two artificial water catchments with well-known ages and under differing starting conditions. The two experimental sites are located in the recultivation area of the lignite open-cast mining district of southern Brandenburg with a distance of approximately 1 km between them. Two different topographies were constructed at the experimental sites: the experimental plot at the catchment Neuer Lugteich was shaped like a dune, whereas the artificial water catchment Hühnerwasser was modelled as an inclined slope. The catchment Neuer Lugteich is four years older than Hühnerwasser. The original substrate at Neuer Lugteich is more sandy and carbonate-free compared to the original substrate dumped at Hühnerwasser. At both sites geomorphological differentiation and crust development were compared and the importance of substrate-dependent water availability and crust type clarified. Once settled, the crusts influenced the water regime of the soils by delaying infiltration through enhanced water repellency, and by limiting water infiltration. Chlorophyll analysis revealed that all crusts were at early stages of development. At Neuer Lugteich, the establishment of the biological soil crusts was closely associated with the vegetation succession, whereas no clear succession of the crusts could be observed at Hühnerwasser. The mosaic-like pattern of the biological soils crusts is associated with the distribution of fine-grained material here.zeige weniger Y1 - 2010 UR - http://geomorphologie.revues.org/8083 U6 - https://doi.org/10.4000/geomorphologie.8083 SN - 1957-777X VL - 16 IS - 4 SP - 359 EP - 370 ER - TY - GEN A1 - Hirsch, Florian A1 - Spröte, Roland A1 - Fischer, Thomas A1 - Forman, Steven L.

T1 - Late Quaternary aeloian dynamics, pedostratigraphy and soil formation in the North European Lowlands - new findings from the Baruther ice-marginal valley T2 - Die Erde N2 - The formation of dunes in central Europe reflects ample sediment supply during the last deglacial hemicycle. A Quaternary inland dune complex in southern Brandenburg, Germany, was studied to frame the duration of pedogenesis in two outcrops containing buried paleosols. An integrative approach, which combined geomorphological, sedimentological, pedological and chronological methods was used to identify aeolian deposition events, ensuing pedogenesis and anthropogenic remobilization. At the outcrops, which were situated approximately 2 km apart from each other, a total of twelve samples of the aeolian sands were dated using optically stimulated luminescence (OSL) and a further six samples using 14C dating. Although the dunes have similar morphological features, these forms have a different history of aeolian sand deposition and pedogenesis. At the older dune (Gl 1) the surface soil is a well developed Podzol, whereas soil development of the younger dune (Gl 2) is clearly in an initial state. The studied sites of the dune complex also differ in grain size distribution and in the presence of buried soils, thereby indicating a climatic impact on aeolian remobilization.

During the remediation of affected soils, knowledge about contaminant concentrations is crucial, but laboratory methods are often expensive and time consuming. Rapid and non-destructive field methods for contaminant determination permit an analysis of large sample numbers and hence, facilitate identification of ‘hot spots’ of contamination. Diffuse near infrared reflectance spectroscopy has proven to be a reliable analytical tool in soil investigation. In order to determine the feasibility of a Polychromix Handheld Field Portable Near-Infrared Analyzer (FP NIR), various sample preparation methods were examined, including homogenizing, sieving, drying, and grinding. Partial least squares calibration models were developed to determine near infrared (NIR) spectral responses to the cyanide concentration in the soil samples.

The risk of groundwater contamination depends mainly on the dissolution of ferric ferrocyanide. In order to design effective reme- diation strategies, it is relevant to understand the contaminant’s fate and transport in soil, and to quantify and mathe- matically model a release rate. The release of iron-cyanide complexes from four contaminated soils, originating from the former MGP in Cottbus, has been studied by using a column experiment. Results indicated that long-term cyanide (CN) release is governed by two phases: one readily dissolved and one strongly fixed. Different isotherm and kinetic equations were used to investigate the driving mechanisms for the ferric ferrocyanide release. Applying the isotherm equations assumed an approach by which two phases were separate in time, whereas the multiple first order equation considered simultaneous occurrence of both cyanide pools. Results indicated varying CN release rates according to the phase and soil. According to isotherm and kinetic models, the long-term iron cyanide release from the MGP soils is a complex phenomenon driven by various mechanisms parallely involving desorption, diffusion and transport processes. Phase I (rapid release) is presumably mainly constrained by the transport process of readily dissolved iron-cyanide complexes combined with desorption of CN bound to reactive heterogeneous surfaces that are in direct contact with the aqueous phase (outer-sphere complexation). Phase II (limited rate) is presumably driven by the diffusion controlled processes involving dissolution of precipitated ferric ferrocyanide from the mineral or inner-sphere complexation of fer- ricyanides. CN release rates in phase I and II were mainly influenced by the pH, organic matter (OM) and the total CN content. The cyanide release rates increased with increasing pH, decreased with low initial CN concentration and were retarded by the increase in OM content.

These contaminations are caused by former Manufactured Gas Plants (MGPs), where electricity for lighting was produced in the process of coal gasification. The production of manufactured gas was restrained in 1950, which caused cessation of MGPs. Our study describes the application of Polychromix Handheld Field Portable Near-Infrared (NIR) Analyzer to predict the cyanide concentrations in soil. In recent times, when the soil remediation is of major importance, there is a need to develop rapid and non-destructive methods for contaminant determination in the field. In situ analysis enables determination of ‘hot spots’, is cheap and time saving in comparison to laboratory methods. This paper presents a novel usage of NIR spectroscopy, where a calibration model was developed, using multivariate calibration algorithms, in order to determine NIR spectral response to the cyanide concentration in soil samples. As a control, the contaminant concentration was determined using conventional Flow Injection Analysis (FIA). The experiments revealed that portable near-infrared spectrometers could be a reliable device for identification of contamination ‘hot spots’, where cyanide concentration are higher than 2400 mg kg-1 in the field and >1750 mg kg-1 after sample preparation in the laboratory, but cannot replace traditional laboratory analyses due to high limits of detection.

T1 - Cross-linked polyacrylates in post-mining substrates: persistence and effects on plant growth T2 - Soil Use and Management N2 - Application of hydrophilic polymers composed of cross-linked polyacrylate can improve soil water-holding capacity and accelerate the restoration of post-mining substrates. In this work, we studied the persistence of a polyacrylate polymer incorporated into a soil and its impact on plant nutrients at a reclamation site of former lignite mining in Lusatia (Germany). In contrast to autumn application, the incorporation of the polymer enhanced the sequestration of plant-derived carbon in the soil, which was reflected by a significant increase in the concentration of a lignin marker. Attenuated total reflexion–Fourier transform infrared spectra (ATR-FTIR) and total elemental contents in the applied polymer suggested an intensive cation exchange between the polymer framework and the soil-forming substrate. In addition, there was an enrichment of carbonaceous material, which seems to reduce the swelling and thus the water-holding capacity of the cross-linked polyacrylate. Conversely, this process protected the polymer structure from rapid decomposition.

The development of such systems, however, has frequently been assumed to depend on boundary and initial conditions including the solid phase. Here, an experimental watershed of about 6 ha surface area was artificially-created in order to imitate an initial stage just at the beginning of the geo-ecosystem development. However, sediment homogeneity could not be achieved for this large-scale field experiment, and the 3D spatial distribution of structures and components remained uncertain. The objective of this study was to quantify and reconstruct the initial sediment distribution and the first development stages using aerial photographs, point information, and a 3D model. The watershed was made of coarse-textured sediments of quaternary origin with a low permeable clay liner as the bottom boundary. A 2D horizontal digital elevation model (DEM) of the surface and a DEM of the subsurface clay layer are used to construct a 3D triangulated numerical grid of the catchment’s initial spatial structure using the 3D-GIS software GOCAD. Physical and chemical soil properties obtained from borehole samples are assigned to this model and interpolated onto the 3D grid. The volumetric changes in space and time are quantified and related to material properties to obtain the mass changes. Correlations between terrain attributes, sediment properties, and mass changes are explored specifically in regions of differing source materials. A temporal sequence of surface DEMs is obtained from photogrammetric, high-precision ground based laser scanning and airborne laser scanning data. 3D models of elevation change are constructed from these DEMs. The processes following the initial state are mainly characterized by runoff-induced erosive mass relocations related to the distribution of surface and subsurface structures and sediment properties. The results suggest that both sediment structures and mass translocations differ between the western and eastern parts of the watershed and that correlations between initial surface structures and subsequent mass changes exist.

T1 - PYROPHOB – A post-fire ecosystem research project to inform management for resilient forest development BT - PYROPHOB – Ein Ökosystemforschungsprojekt auf Waldbrandflächen als Grundlage für das Management einer resilienten Waldentwicklung T2 - Tuexenia N2 - PYROPHOB (fire-resistant) is the name of an interdisciplinary research project that is running for five years from 2020 to 2025. In this project, eight institutions are investigating the ecological effects of wildfires and subsequent forest management strategies in pine forests (plantations) in Brandenburg (NE Germany), with the aim of formulating practical recommendations for managing fire-prone forests and the effective restoration of post-fire forest areas. We provide a brief overview of what is known about the effects of wildfire on abiotic and biotic parameters in temperate pine forests, as well as the effects of silvicultural treatments. To date, we know little about how different components of biodiversity are linked in post-fire forest ecosystems and how management affects their functioning. By describing the project, we illustrate the requirements for the implementation of such an applied research project. We emphasize the importance of the study design for dealing with interdisciplinary questions and for the quantitative synthesis of research results. The project comprises a set of standardised field plots in two wildfire areas covering different post-fire management options. Fifteen study sites were established, including two reference sites in unburned pine stands, each with ten study plots as replicates. In situ nitrogen mineralisation, litter decomposition tests and soil biological activity are used for soil biological characterisation. Microclimate data is measured continuously. Standing and lying dead wood and tree regeneration are recorded as key indicators of the success of forestry treatments. Further methods com-prise terrestrial laser scanning, remote sensing techniques as well as surveys of vegetation and above and below ground biomass. Identification of fruiting body-forming fungi, phytoparasites and ectomycorrhizal fungi is supported by marker gene sequencing. Faunistic indicators comprise predatory soil arthropods (pairs of emergence tents and soil traps), saproxylic beetles (flight traps and funnel traps), moths (automated window traps), mammals (camera traps), and breeding birds (visual and acoustic observation). We discuss the strengths and limitations of the project design. We are able to systematically capture short-term temporal shifts in parameters and trends in post-fire ecosystem development. Research in a real landscape with ongoing environmental changes and interventions pres-ents challenges for experimental design, data analysis and interpretation. The drivers of ecosystem development are rarely completely independent or perfectly balanced, and lack of replication is ine-vitable. The two fires did not occur in the same year and season, resulting in different initial conditions for the colonisation of the burned areas. Finally, a large part of one study area was again affected by a fire in 2022, which destroyed direct comparability with the other sites. Despite these obstacles the project has started to generate valuable results to address management and conservation challenges.

Manifold approaches exist and according to the DIN ISO 11277 soil texture is analyzed by default with the combined pipette sieving and sedimentation method developed by Köhn.With this standard technique subfractions of sand and silt as well as the total clay content can be determined but the differentiation of clay subfractions is impossible. As the differentiation of the clay subfractions yields relevant information about pedogenesis, we present a protocol basing on standard techniques of granulometry with easy to handle and low cost equipment. The protocol was tested on a set of soil samples to cover the range of grain size distributions.

For the Pyrenees an asynchronous maximum ice extent compared to the global last glacial maximum (LGM) is controversially discussed. Our study sites are located in the Central Spanish Pyrenees, namely the Aragon and Gallego Valley. Both valleys are type locations for the Pleistocene glaciations and the early maximum ice extent for the Pyrenees was dated amongst other sites in the Gallego Valley to about 36 ka. Due to the potential time span since the earlier deglaciation compared to LGM sites from Central Europe we used a pedological and sedimentological approach to reconstruct the Late Quaternary landscape development. Our results indicate a considerable reshaping of the LGM landscape prior to the onset of the Holocene. The LGM tills are covered by a deposit with high content of fine sand and coarse silt. On the slopes the clasts in these fine-grained sediments are aligned parallel to the slope direction, whereas in the underlaying tills the clasts are aligned rectangular to the slope direction and therefore representing the direction of the Pleistocene glacier movement.We attribute the alignment of the clasts in the sediment covering the tills to solifluction induced by periglacial conditions. The high contents of coarse silt and fine sand are also characteristic for the eolian component in periglacial slope deposits. OSL datings suggest an age of about 14 ka for these sediments. Soil micromorphology shows that the periglacial deposits were not subject to intensive pedogenic processes prior to the sedimentation but that profiles are strongly affected by lessivation after deposition. Soil erosion is only evident during the Holocene and we associate these phases of soil erosion with the human impact. We found no indications for geomorphologic and pedogenic processes between the reported deposition of the LGM till around 36 ka and theperiglacial conditions dated in our study to about 14 ka.

N2 - This study aims to characterize the Late Quaternary stratigraphy in a type region of Pleistocene glaciation in the Central Spanish Pyrenees by using geophysical prospection techniques to extrapolate stratigraphical field information from soil pits. The main objectives are (i) to identify the thickness of the Quaternary sediments, (ii) to characterize the internal structures and stratifications within the Quaternary deposits and (iii) to test the validity of combined geophysical prospection techniques, including shallow seismic refraction (SSR) and electric resistivity tomography (ERT). We focus on two selected study sites: the Late Pleistocene terminal moraine at Senegüé on the bottom of the Gállego Valley and a Pleistocene non-glaciated slope located nearby. This study proves that information about the depth, structure and distribution of Late Quaternary sediments (glacial, periglacial and fluvial) can be gathered by the combination of geophysical techniques (SSR and ERT). These techniques allow for a reliable, inexpensive and fast extrapolation of stratification information from soil pits and enable Late Quaternary and Eocene sediments to be distinguished. The reconstruction of the sediment genesis is facilitated by the geophysical techniques due to the potential to prospect the internal structures of large areas.

By employing multiple field and laboratory methods, several sediment facies (glacial, periglacial, fluvial and anthropogenic induced colluvial displacement) can be distinguished. Due to small scale horizontal and vertical distribution of the Quaternary sediments, the genetic differentiation is crucial for the dating of periglacial and glacial phases. The polygenetic sediment sequences indicate periods of post-glacial geomorphodynamic, probably induced by changing climatic or anthropogenic influences. The glacial sediments are preserved as lateral and terminal moraines. Due to the arrangement of the moraines, several Pleistocene glacial advances can be recognized. Cold climate conditions led to the formation of periglacial slope deposits which are classified as lower and upper heads in accordance to findings from Central Europe (Raab & Völkel 2003, Raab et al. 2010). Although lower heads are restricted to the Pleistocene extraglacial landscape, upper heads can be located in the Pleistocene extraglacial and glacial landscape. Upper heads are characterized by a high amount of silt, which is interpreted as the result of an aeolian admixture. The aeolian component is not limited to the upper head but can also be found as loess deposit on glaciofluvial and fluvial terraces. Due to the characteristically low inclination of the terraces the aeolian cover was only sparsely affected by erosion. On the other hand, on steeper slopes, intensive land use results in residual shallow sediment cover above the bedrock in the upper slopes and deep colluvial layers on the foot slopes and valley bottoms.
