This model simulates groundwater dynamics in the Pleistocene aquifers of the Lower Rhine lignite mining area (Germany). GROWA uses an area-differentiated approach to calculate recharge rates depending on runoff-relevant site characteristics, which are represented by a set of baseflow indices. The regional accuracy of the coupled groundwater and GROWA models has been checked using groundwater hydrographs as validation criteria. The results suggest that the current (unadjusted) version of GROWA underestimates the regional groundwater recharge rate by 10-20 mm/yr. The comparative analysis identified areas where recharge calculations could be improved by adjusting the baseflow indices for areas where runoff is dominated by slope, low water-logging and a low degree of sealing. Using the adjusted set of baseflow indices, the mean groundwater recharge rate of the Rurscholle region was modelled as approx. 170 mm/yr. This study highlights the benefit of using a coupled approach and being able to independently calibrate and validate groundwater recharge boundary conditions in regional groundwater models.}, language = {en} } @misc{OPUS4-7196, title = {Indikatoren im Grundwasser - Tagung der Fachsektion Hydrogeologie in der DGG, Cottbus, 24.-28.05.2006}, editor = {Voigt, Hans-J{\"u}rgen and Kaufmann-Knoke, Ruth and Jahnke, Christoph and Herd, Rainer}, publisher = {Deutsche Gesellschaft f{\"u}r Geowissenschaften}, address = {Hannover}, isbn = {3-932537-39-4}, pages = {166}, abstract = {Kurzfassungen der Vortr{\"a}ge und Poster Tagung der Fachsektion Hydrogeologie in der Deutschen Gesellschaft f{\"u}r Geowissenschaften (FH-DGG), Cottbus, 24.-28.05.2006}, language = {de} } @book{KnoedelLangeVoigtetal., author = {Kn{\"o}del, Klaus and Lange, Gerhard and Voigt, Hans-J{\"u}rgen and Bohn, Antje and Jenn, Florian and Liese, Manja and Nagare, Ranjeet and Nitsche, Claus and Petzold, Hellfried and Radschinski, Jens}, title = {Environmental Geology - Handbook of Field Methods and Case Studies}, publisher = {Springer}, address = {Berlin [u.a.]}, isbn = {978-3-540-74669-0}, abstract = {This handbook describes a broad spectrum of methods in the fields of remote sensing, geophysics, geology, hydrogeology, geochemistry, and microbiology designed to investigate landfill, mining and industrial sites.

Chemical analyses from hydrocarbon exploration campaigns showed evidence of the existence of two different groups of brines: halite and halite Ca-Cl brines. Residual brines and leachates are identified by Br-/Cl- ratios. Most of the brines are dissolution brines of Permian evaporites. New analyses show that the pattern of rare-earth elements and yttriurn (REY) are closely linked to H and O isotope distribution. Thermal brines from deep wells and artesian wells indicate isotopically evaporated brines, which chemically interacted with their aquifer environment. Isotopes and rare-earth element patterns prove that cross flow exists, especially in the post-Rupelian aquifer. However, even at depths exceeding 2,000 m, interaquifer flow takes place. The rare-earth element pattern and H and O isotopes identify locally ascending brines. A large-scale lateral groundwater flow has to be assumed because all pre-Rupelian aquifer systems to a depth of at least 500 m are isotopically characterised by Recent or Pleistocene recharge conditions.}, language = {en} } @article{VoigtJennNitsche, author = {Voigt, Hans-J{\"u}rgen and Jenn, Florian and Nitsche, Claus}, title = {European strategies of groundwater monitoring for different aims}, abstract = {Groundwater monitoring systems play an important role in the implementation of the EU WaterFramework Directive.

The range of natural groundwater concentrations is characterized by confidence intervals of the distribution function of the natural component. The applicability of the approach was established for 17 hydrochemical different groundwater typologies occurring throughout Germany. Based on groundwater monitoring data from ca. 26,000 groundwater-monitoring stations, 40 different hydrochemical parameters were evaluated for each groundwater typology. For all investigated parameters the range of natural groundwater concentrations has been identified.
