MODELING OF GROUNDWATER FLOW OVER SLOPING BEDS IN RESPONSE TO CONSTANT RECHARGE AND STREAM OF VARYING WATER LEVEL
This paper presents an analytical model characterizing unsteady groundwater flow in an unconfined aquifer resting on a sloping impervious bed. The aquifer is in contact with a constant water level at one end. The other end is connected to a stream whose level is increasing form an initial level to a final level at a known exponentially decaying function of time. Moreover, the aquifer is repleni...

متن کاملGroundwater Flow and Salinity Intrusion Simulation in Malekan Plain Aquifer
Due to groundwater overextraction, during the recent years, Malekan plain aquifer has been faced to a risk of increasing salination. The groundwater flow model of the plain was designed, invesitagion of groundwater flow regime and precise hydraulic parameters estimation, utilizing the various method such as geological surveys, tomography methods, hydrochemical analysis and simulation of aquife...
متن کاملDeep groundwater mediates streamflow response to climate warming in the Oregon Cascades
Recent studies predict that projected climate change will lead to significant reductions in summer streamflow in the mountainous regions of the Western US. Hydrologic modeling directed at quantifying these potential changes has focused on the magnitude and timing of spring snowmelt as the key control on the spatial–temporal pattern of summer streamflow. We illustrate how spatial differences in ...
متن کاملQuantification of Groundwater Recharge from an Ephemeral Stream into a Mountainous Karst Aquifer
Sustainable groundwater production from karst aquifers is primarily dictated by its recharge rate. Therefore, it is essential to accurately quantify annual groundwater recharge in order to limit overexploitation and to evaluate artificial methods for groundwater enrichment. Infiltration during erratic flood events in karst basins may substantially contribute to aquifer recharge. However, the co...
