The S/0 model incorporates both operations research linear programming and evolutionary optimization genetic algorithm (GA). Differing from a previously reported GA code that treats pumping as a discrete variable (no pumping or pumping at some specified rate), this code treats pumping as a continuous variable. It was used to design the cleanup wells which would reduce contaminant concentrations to acceptable values within 6 years. The linear programming capability of REMAX was then used to determine the least amount of extra pumping needed to achieve plume containment. Results of this optimization approach will be presented

Managing stream aquifer systems during a dry season requires using finer discretization in time and space. Presented is a computer model, US/REMAX, developed by Utah State University personnel for aiding best management of stream-aquifer systems for both long and short eras. The model computes strategies for optimally allocating surface and ground water resources in time and space. For a water supply problem the model can maximize the sum of delivered surface and ground water. For an environmental protection problem the model can minimize total groundwater pumping (extraction plus injection) needed to capture contaminant plume. The model can provide optimal steady-state or time variant solutions. Weighting coefficients can be used in the objective function: (1) to emphasize substitution of surface water diversion for groundw...
