Surface Water Resources

Surface water resources provide water supply for public water systems, domestic, power generation, industries, mining, agriculture, navigation, recreation and instream water need for aquatic ecosystem. It is critical for the state’s economy and wellbeing of its citizens to ensure adequate, reliable, clean and affordable water supply to meet water demand for residents and industries in Illinois for now and the future. Drought, the second most costly natural hazard in the United States, could have substantial adversary impact on surface water supplies and low streamflow in Illinois, causing substantive economic loss especially on crops and sensitive aquatic species. On average, drought causes annual losses of about $9 billion for 1980-2019 (in CPI-adjusted 2019 values). This program provides scientific studies supporting water supply planning (surface water) which is one of the core activities of the ISWS, going back at least 100 years and mandated by the state legislatives. This program explores the hydrologic modelling, stochastic hydrology, water-energy nexus analysis, system analysis, and multi-objective optimization to provide scientific data and information for informed decision making on sustainable water resources management. Primary studies and research on surface water resources include:
