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} } @book{LieseNagareJahnkeetal., author = {Liese, Manja and Nagare, Ranjeet and Jahnke, Christoph and Voigt, Hans-J{\"u}rgen}, title = {12 Jahre Pilotbetrieb Karolinenh{\"o}he - zusammenfassende Auswertung}, editor = {Heinzmann, Bernd and Dlubek, Heidi}, publisher = {Berlin : Kompetenzzentrum Wasser Berlin}, isbn = {978-3-9811684-2-6}, language = {de} } @techreport{KempkaHerdHuengesetal., author = {Kempka, Thomas and Herd, Rainer and Huenges, Ernst and Jahnke, Christoph and Janetz, S. and Jolie, Egbert and K{\"u}hn, M. and Margi, F. and M{\"o}ller, M. and Munoz, Gerard and Ritter, Oliver and Schafrik, Wladislaw and Schmidt-Hattenberger, Cornelia and Tillner, Elena and Voigt, Hans-J{\"u}rgen and Zimmermann, G.}, title = {CO2-Speicherung in Ostbrandenburg: Implikationen f{\"u}r eine synergetische geothermische Energiegewinnung und Konzeptionierung eines Fr{\"u}hwarnsystems gegen Grundwasserversalzung}, address = {Potsdam [u.a.]}, pages = {125}, language = {de} } @incollection{KempkaHerdHuengesetal., author = {Kempka, Thomas and Herd, Rainer and Huenges, Ernst and Endler, Ricarda and Jahnke, Christoph and Janetz, Silvio and Jolie, Egbert and K{\"u}hn, Michael and Magri, Fabien and Meinert, Peter and Moeck, Inga and M{\"o}ller, Marcus and Munoz, Gerard and Ritter, Oliver and Schafrik, Wladislaw and Schmidt-Hattenberger, Cornelia and Tillner, Elena and Voigt, Hans-J{\"u}rgen and Zimmermann, G{\"u}nter}, title = {Geological Storage of CO2 - Long Term Security Aspects}, editor = {Liebscher, Axel and M{\"u}nch, Ute}, publisher = {Springer}, address = {Berlin [u.a.]}, isbn = {978-3-319-13929-6}, pages = {183 -- 209}, language = {en} } @incollection{KempkaHerdHuengesetal., author = {Kempka, Thomas and Herd, Rainer and Huenges, Ernst and Endler, Ricarda and Jahnke, Christoph and Janetz, Silvio and Jolie, Egbert and K{\"u}hn, Michael and Magri, Fabien and Meinert, Peter and Moeck, Inga and M{\"o}ller, Marcus and Munoz, Gerard and Ritter, Oliver and Schafrik, Wladislaw and Schmidt-Hattenberger, Cornelia and Tillner, Elena and Voigt, Hans-J{\"u}rgen and Zimmermann, G{\"u}nter}, title = {Joint Research Project Brine: Carbon Dioxide Storage in Eastern Brandenburg; Implications for Synergetic Geothermal Heat Recovery and Conceptualization of an Early Warning System Against Freshwater Salinization}, series = {Geological Storage of CO2 - Long Termim Security Aspects}, booktitle = {Geological Storage of CO2 - Long Termim Security Aspects}, editor = {Liebscher, Axel and M{\"u}nch, Ute}, publisher = {Springer}, address = {Cham Switzerland}, isbn = {978-3-319-13929-6}, doi = {10.1007/978-3-319-13930-2}, pages = {183 -- 208}, language = {en} } @book{HeinkeleVoigtJahnkeetal., author = {Heinkele, Thomas and Voigt, Hans-J{\"u}rgen and Jahnke, Christoph and Hannappel, Stephan and Donat, E.}, title = {Charakterisierung der Empfindlichkeit von Grundwasserk{\"o}rpern}, publisher = {Umweltbundesamt}, address = {Berlin}, pages = {117}, language = {de} } @inproceedings{KempkaHerdHuengesetal., author = {Kempka, Thomas and Herd, Rainer and Huenges, Ernst and Jahnke, Christoph and K{\"u}hn, Michael and Moeck, Inga and Munoz, Gerard and Ritter, Oliver and Schmidt-Hattenberger, Cornelia and Voigt, Hans-J{\"u}rgen and Zimmermann, G{\"u}nter}, title = {brine - CO2 storage in eastern Brandenburg:Implications for geothermal heat provision and conception of a salinisation early warning system}, editor = {Schueth, C.}, language = {en} } @techreport{Jahnke, author = {Jahnke, Christoph}, title = {Hydraulisches Monitoring Schachtanlagen und Gruben des Kalibergbaus 2015 - Gruben/Schachtanlagen; Neu-Staßfurt Schacht V, Grube Brefeld/Tarthun, Staßfurt Heydt/Manteuffel, Schacht Leopoldshall III, Bernburg Schacht Solvayhall II, Schacht Peißen, Schacht Pl{\"o}mnitz, Lichtloch 31 Strenznaundorf}, editor = {Herd, Rainer}, publisher = {Brandenburgische Technische Universit{\"a}t, Fakult{\"a}t 4 Umweltwissenschaften und Verfahrenstechnik, Lehrstuhl Rohstoff- und Ressourcenwirtschaft}, address = {Cottbus}, pages = {34}, language = {de} } @article{TesmerMollerWielandetal., author = {Tesmer, Maja and Moller, P. and Wieland, S. and Jahnke, Christoph and Voigt, Hans-J{\"u}rgen and Pekdeger, Asaf}, title = {Deep reaching fluid flow in the North East German Basin: origin and processes of groundwater salinisation}, abstract = {Major element chemistry, rare-earth element distribution, and H and 0 isotopes are conjointly used to study the sources of salinisation and interaquifer flow of saline groundwater in the North East German Basin. 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} }
