The seasonal movement of soil water through a deep vadose zone of a sandy hill was studied in the central part of The Netherlands. The behaviour of soil water was tracked by monitoring soil water fluctuations and changes in the environmental tracer 0 in vertical profiles at test sites with grassland, heathland and forest. In the temperate climate of the study area a soil moisture deficit develo...

abstract microbial contaminants transport to groundwater is a serious environmental problem that can result in large outbreaks of waterborne diseases. some of bacteria can travel from vadose zone and cause contamination of groundwater resources. thus, an accurate prediction of transport and fate of pathogenic microorganisms in unsaturated soil is needed to protect groundwater resources. the mai...

bazargan and poldasht plains are located in the north of west azarbaijan, northwest of iran. in this area, groundwater supplies main water demands. aim of this research is assessment of aquifer vulnerability for contamination potential on the basis of hydrogeological conditions of the study area. for this purpose the combined use of the drastic and geographical information system (gis) demonstr...

Source water protection in areas of shale gas development encompasses identifying that are the most vulnerable to groundwater quality deterioration due spills natural production wastewater. This study uses density-dependent flow and transport code TOUGH2 quantify time distance travel saline wastewater plumes for different hydrogeological settings Northeast British Columbia. The models were desi...
