Calculate Streamflow Depletion by Nearby Pumping Well 

This web site provides links relevant to the computer program STRMDEPL08.  This program evaluates analytical solutions estimating streamflow depletion by a pumping well.  STRMDEPL, a computer program using two analytical solutions to calculate streamflow depletion by a nearby pumping well was extended to account for two additional analytical solutions. The extended program is named STRMDEPL08. The original program evaluated the solutions for a stream that fully penetrates the aquifer with and without streambed resistance to ground-water flow. The modified program evaluates solutions for a partially penetrating stream with streambed resistance and for a stream in an aquitard subjected to pumping from an underlying leaky aquifer. The code also was modified to allow the user to input pumping variations at other than 1-day intervals.
