Enhancing Reservoir Operations: Decision-Making in Uncertain Environments

This model focuses on improving reservoir operations through advanced decision-making strategies in an uncertain world. It utilizes the continuity equation to balance multiple objectives like flood control, conservation, and hydroelectric power generation. Key processes such as inflow, evaporation, and sedimentation are represented to optimize reservoir management. The approach considers both operational controls and environmental impacts, addressing challenges like maintaining fish habitats and ensuring municipal water supply. Explore effective solutions to enhance reservoir performance and sustainability.

  1. Reservoir Operations Modeling Making Better Decisions in an Uncertain World

  2. Modeling Reservoirs • Continuity Equation • Balance multiple objectives • Represent operational controls

  3. Basic Processes Inflow Evaporation Spillway Reservoir Seepage Sedimentation Outlet

  4. Reservoir Pools Dam Freeboard Surcharge Flood Control Conservation Dead Pool

  5. Dead Pool • “Inactive” pool • Maintain head for hydroelectric power • Fish habitat • Sediment reserve

  6. Conservation Pool • Municipal & industrial supply • Irrigation • Navigation/recreation • Hydroelectric Power • Instream flow maintenance

  7. Seasonal Conservation Pool Surcharge Flood Control Pool Reservoir Elevation Conservation Pool Inactive Pool Months (Jan – Dec)

  8. Flood Control • Remains empty • Weir or Orifice • Downstream control • Upstream control

  9. Surcharge • Weir flow over spillway • Uncontrolled storage capacity • Presents risk downstream • Never overtop dam under any condition

  10. Flood Control vs. Conservation • Continuous balancing act • Model impacts • Policy changes • New facilities • New supplies
