The major purpose of the study was to indicate that the goals of urban water management, with respect to the use and further development of systems analysis tools explored, are attainable. It was primarily a technical enterprise to demonstrate that a comprehensive model could be constructed in a general enough format to allow its application to many urban water systems while at the same time urban water subsystem submodels, comprising the larger model, could be operated independently to describe behavior of specific urban subsystems. Economic aspects were also considered. A comprehensive simulation model was developed for a specific hypothetical urban water resources system structured to indicate the interrelationships among inflows, storage volumes, outflows, and qualities in various subsystems. A more expensive but more refined storm water modeling project was described. An economic systems model was formulated to evaluate physical works projects intended to meet urban water objectives subject to technical and budgetary constraints. Results of the hypothetical demonstrations of the technical and economic models were given. Major conclusions and recommendations were presented. (WRSIC abstract)
