Water resource planning and management has greatly benefited from the use of computer modeling. Numerous computer models have been developed to predict expected outcomes given a set of input data and logical constraints. A supply and demand model (SDAM) has been developed in Lotus 1-2-3 by the Lower Colorado River Authority which incorporates information from several computer models. This model has been successfully used to evaluate the ability of ground- and surface-water supplies to meet projected annual water demands for water use categories in its statutory 10-county district. The Lower Colorado River Authority is currently using this model as one input in determining a commitment of water for future water users from its existing water supply reservoirs.
