Abstract: Water flow through vadose zone is important for soil ecology and for groundwater development. A thorough knowledge of water flow and solute transport through unsaturated zone is also needed for sustainable irrigation ...

Abstract: Variations in groundwater flow regimes due to direct draining/pumping and surrounding climatic variabilities may significantly affect the spatial and temporal distribution of hydrocarbon compounds in the subsurface. The ...

Abstract: The focus of this study was to investigate the fate and transport of toluene, a light nonaqueous-phase liquids (LNAPLs) in the subsurface region under dynamic groundwater table conditions. A series of experiments were ...

Abstract: An integrated experimental-numerical approach is used in this study to bioremediate a toluene, a nonaqueous phase liquid (NAPL), contaminated land site, having varying moisture and temperature levels. The rates of ...

Abstract: Pollution from animal wastes is a threat to water resources. Insufficient treatment and disposal of animal manure results in potential runoff and transport of waste into surface and groundwater and ultimately contaminating ...
