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.}, language = {en} } @inproceedings{MaurerSchneiderBuczkoetal., author = {Maurer, Thomas and Schneider, Anna and Buczko, Uwe and Gerke, Horst H.}, title = {Reproducing the initial internal structural heterogeneity of an artificially created catchment}, series = {Structures and processes of the initial ecosystem development, 1st International Conference assoc. with 4th Meeting of Young Researchers in Earth Sciences (MYRES), 20-24 Sept. 2010, Cottbus, Germany}, booktitle = {Structures and processes of the initial ecosystem development, 1st International Conference assoc. with 4th Meeting of Young Researchers in Earth Sciences (MYRES), 20-24 Sept. 2010, Cottbus, Germany}, publisher = {BTU}, address = {Cottbus}, pages = {76 -- 77}, language = {en} } @inproceedings{MaurerSchneiderBuczkoetal., author = {Maurer, Thomas and Schneider, Anna and Buczko, Uwe and Gerke, Horst H.}, title = {Generating the 3D internal sediment structure of an artificial catchment}, series = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, booktitle = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{MaurerSchneiderBuczkoetal., author = {Maurer, Thomas and Schneider, Anna and Buczko, Uwe and Gerke, Horst H.}, title = {Modelling the structural heterogeneity of an artificial hydrological catchment}, series = {EGU General Assembly 2011, Vienna, Austria, 03 - 08 April 2011}, booktitle = {EGU General Assembly 2011, Vienna, Austria, 03 - 08 April 2011}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, pages = {11803}, language = {en} } @inproceedings{SchneiderMaurerGerke, author = {Schneider, Anna and Maurer, Thomas and Gerke, Horst H.}, title = {3D-r{\"a}umliche Beschreibung initialer Sedimentumverteilung in einem k{\"u}nstlichen Einzugsgebiet}, series = {B{\"o}den verstehen, B{\"o}den nutzen, B{\"o}den fit machen, Jahrestagung der Deutschen Bodenkundlichen Gesellschaft, 3. - 9.
