Planning Groundwater Supply Systems for Urban Growth: Application to West Lafayette, Indiana

摘要

In water supply systems, predicting the spatial disaggregation of the demand is one of major concern. In this study a landuse allocation model is used for this purpose. The future zonewise development of different landuse activities is converted into an equivalent water demand based on the requirements of the activities projected. Other important facets are the determination of optimal locations of water wells and of distribution reservoirs along with the optimal flow values and pipe sizes. The annualized cost of the well field, distribution reservoirs, pipes and pumping is minimized. The indivisibility requirement of the number of wells and reservoirs and the continuous variation of flow values require the use of a Mixed Integer Programming (MIP) approach for the optimization. The nonlinear head losses result in nonlinear objective function and constraints.
