Supplemental Information and Data for uncertainty analysis and identification of key parameters controlling bacteria transport within a riverbank filtration scenario (submitted to Water Resources Research)

Knabe, Dustin ; Guadagnini, Alberto ; Riva, Monica ; Engelhardt, Irina (2020)

This dataset includes Supplemental Information and Data for research paper: Knabe, D., Guadagnini, A., Riva, M., Engelhardt, I.: Uncertainty analysis and identification of key parameters controlling bacteria transport within a riverbank filtration scenario (Water Resources Research).

Development of a fully coupled biogeochemical reactive transport model to simulate microbial oxidation of organic carbon and pyrite under nitrate‐reducing conditions

Knabe, Dustin ; Kludt, Christoph ; Jacques, Diederik ; Lichtner, Peter ; Engelhardt, Irina (2018-11-23)

In regions with intensive agriculture nitrate is one of the most relevant contaminants in groundwater. Denitrification reduces elevated nitrate concentrations in many aquifers, yet the denitrification potential is limited by the concentration of available electron donors. The aim of this work was to study the denitrification potential and its limitation in natural sediments. A column experiment...

Reservoir-scale transdimensional fracture network inversion

Somogyvári, Márk ; Kühn, Michael ; Reich, Sebastian (2019-11-08)

The Waiwera aquifer hosts a structurally complex geothermal groundwater system, where a localized thermal anomaly feeds the thermal reservoir. The temperature anomaly is formed by the mixing of waters from three different sources: fresh cold groundwater, cold seawater and warm geothermal water. The stratified reservoir rock has been tilted, folded, faulted, and fractured by tectonic movement, p...

Detection of Karst Features in the Black Hills Area in South Dakota/Wyoming, USA, Based on Evaluations of Remote Sensing Data

Theilen-Willige, Barbara (2018-05-28)

Landsat 8, Sentinel 2, Aster, RapidEye and PlanetScope data and Sentinel 1- and Advanced Land Observing Satellite (ALOS)-Phased Array type L-band Synthetic Aperture Radar (PALSAR)-radar images have been evaluated for a karst feature inventory in the Black Hills area in Wyoming/South Dakota, USA. The GeoInformation System (GIS) integrated evaluation of the different satellite data included as we...

Reassessing Hydrological Processes That Control Stable Isotope Tracers in Groundwater of the Atacama Desert (Northern Chile)

Scheihing, Konstantin W. ; Moya, Claudio E. ; Struck, Ulrich ; Lictevout, Elisabeth ; Tröger, Uwe (2017-12-26)

A collection of 514 stable isotope water samples from the Atacama Desert is being reassessed geostatistically. The evaluation reveals that adjacent Andean catchments can exhibit distinct δ18O and δ2H value ranges in meteoric waters, despite similar sample altitudes of up to 4000 m above sea level (a.s.l.). It is proposed that the individual topographic features of each catchment at the western ...

Water and water shortage Iran

Ghader, Fatemeh (2018-10-22)

Tashk-Bakhtegan and Maharlu lakes' basin in Fars province in the south of Iran is facing a harsh water shortage in recent years. In this study for the first time, a complete research was carried out to understand the hydrologic circle of Tashk-Bakhtegan and Maharlu lakes' basin. In this study those basins were evaluated in terms of meteorology, surface water, groundwater, water quality, and wa...

Water and water shortage in Iran

Ghader, Fatemeh (2018)

Tashk-Bakhtegan and Maharlu lakes' basin in Fars province in the south of Iran is facing a harsh water shortage in recent years. Semi-dry and dry conditions are prevailing climate conditions in the basin and the wet condition can only be seen in the small part of the north. Groundwater is the main source to provide water for different purposes such as agriculture, industry and drinking. Over-ex...
