STRMDEPL, a one-dimensional model 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 incorporated solutions for a stream that fully penetrates the aquifer with and without streambed resistance to ground-water flow. The modified program includes 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. The modified code is shown to correctly evaluate the analytical solutions and to provide correct results for half-day time intervals.
