Integrated land surface-groundwater models are valuable tools in simulating the terrestrial hydrologic cycle as a continuous system and exploring the extent of land surface-subsurface interactions from catchment to regional scales. However, the fidelity of model simulations is impacted not only by the vegetation and subsurface parameterizations, but also by the antecedent condition of model sta...

Introduction: Arsenic contamination of  surface and groundwater has been categorizd among high profile  environmental  problems around the world. The matter is of most concern where unsafe water is used for drinking. Sahand region reservoir in northwest of Iran supplies water for drinking, industrial and agricultural purposes throught  irrigation  of 11000 hectares of l...

the paper presents the case study of the current formation of a brazilian pit lake from an iron ore mining activity. the water used for the filling of the lake comes from rain, ground water and the complementary pumpage from a close river. at its final stage, which will be reached around year 2018, lake aguas claras will have a surface area of 0.67 km2 and the depth of 234 m, which will make it...

according to recent studies, about 60 percent of surface waters and 57 percent ground waters are located in snowy zones in iran. in most areas of northern hemisphere and alpine environment areas, snow melt lead to the maximum instantaneous flow rate and is an important part of annual discharge. the present study investigated the effect of snowmelt on the surface waters and ground waters in baha...
