The Water Resources Planning and Management Division is unique in providing a linkage of the technologies available in the existing water-related disciplines in civil engineering, including hydrology, hydraulics, groundwater, and environmental engineering, with interdisciplinary studies in economics, water law, natural science, mathematics, statistics, computer science, and decision science, for the purpose of providing graduate training and conducting interdisciplinary research in water resources planning and management. The decision-making focus of the WRPM Division places emphasis on application of advanced computer technology, decision support systems, geographic information systems, mathematical programming, and artificial intelligence to water resources and environmental systems. These tools are applied to complex multiple objective problems involving analysis of multi-facility, multi-purpose systems requiring coordinated planning, management, and operations for water supply, hydropower, flood control, irrigation, wastewater management, water quality control, ecological enhancement, and conjunctive use of groundwater and surface water.
