Modeling Integrated Decisions For A Municipal Water System With Recourse And Uncertainties: Amman, Jordan, David E. Rosenberg, Jay Lund
Modeling Integrated Decisions For A Municipal Water System With Recourse And Uncertainties: Amman, Jordan, David E. Rosenberg, Jay Lund
Civil and Environmental Engineering Faculty Publications
Stochastic mixed-integer optimization is used to identify a portfolio of long- and short-term supply and conservation actions for a municipal water system to cost-effectively accommodate a distribution of water shortages. Alternative robust, grey-number, and best/worst case formulations systematically explore implications of uncertainties in action costs, life spans, water volumes gained or saved, shortage levels, and shortage probabilities. A detailed example for Amman, Jordan considers 23 potential actions. Results show: (1) remarkable consistency occurs across the different modeling approaches. (2) Conserving water—reducing leakage and targeting select customers to install water efficient appliances—plays an important and growing role over time. (3) A …
Integrated Water Resources Management And Modeling At Multiple Spatial Scales In Jordan, David E. Rosenberg
Integrated Water Resources Management And Modeling At Multiple Spatial Scales In Jordan, David E. Rosenberg

Water shortages from intermittent public supplies are a major and expanding problem in the Hashemite Kingdom of Jordan. Yet individual users, utility managers, and government officials can improve access or cope with shortages in many ways. New supplies, more efficient use of existing resources, long-term investments to expand infrastructure and reduce leakage, and short-term measures to flexibly transfer, ration, or curtail some uses represent several different approaches for management. This paper reviews three separate systems analysis that use stochastic optimization with recourse. Analysis for individual residential users, the water utility serving 2.2 million residents in the capital Amman, and the …
