  1. Multiple PurposeDam & Reservoir

  2. Objectives • Describe real-time water control mission • Introduce new Corps Water Management System (CWMS) • Concepts • Components • Models • Products • Applications • Questions ??

  3. Perspective • Corps regulates 700 reservoirs nationwide • Real-time water control management decisions are driven by observed data & forecasted conditions • There is need for a swift, accurate, & reliable data management system to support real-time decision making

  4. Julie’s District Slide Susquehanna & Potomac River Basins

  5. Water Control Mission To regulate reservoir projects, in real time, for in-lake and downstream benefits in accordance with authorized project purposes

  6. Project Purposes & Benefits Flood Control Recreation Water Supply Water Quality Hydropower Flow Augmentation (Navigation)

  7. Real-TimeWater Control Data Precipitation Observed Downstream Flow Downstream Flood Level Reservoir Discharge

  8. Water Control Management SERVERS Weather Forecast Data Processing Data Storage Modeling Observed Data Public and Cooperators Field Office Instructions Water Control Management Decisions

  9. Corps Water Management System An integrated system of hardware, software, and communication resources supporting the Corps’ real-time water control management mission

  10. CWMS Development • HEC - system developer • CURG - requirements, design, & testing • Status • Concepts: mid-1990’s • Development: 1997 to 2001 • Field deployment: 2001 to 2002 • Current version: 1.3

  11. CWMS Components Data Base Data Collection Watershed Modeling Information dissemination Data Visualization

  12. Data Acquisition • Collect: • Real-time data: observed stream flow, precipitation, temperature, water quality, gate settings, reservoir levels, etc. • Static data: physical data for model development • Decode • Validate • Transform

  13. Data Storage • ORACLE is CWMS database • Interfaces with other databases (incl DSS) • Accessible by multiple users • Modeling • Extracts data for analyses • Posts results for decision-making

  14. Data Visualization

  15. Data Dissemination • Common information source • Data & information placed on WEB-based platform • Available to Corps users & outside interests • Real-time availability

  16. Watershed Modeling (Hydrology) (Storage) HMS ResSim FIA RAS (Damages) (Hydraulics) Watershed Modeling

  17. HEC-HMSHydrologic Modeling System Computes runoff from observed & forecasted precipitation

  18. HEC-RESSIM Reservoir Simulation System Simulates reservoir regulation using inflow hydrographs & project characteristics

  19. HEC-RASRiver Analysis System Analyzes river hydraulics to compute water depth, velocity, & inundation boundaries

  20. HEC-FIAFlow Impact Analysis Assesses damages & benefits based on river stage

  21. Real-Time Forecast I see Hurricane Ivan in your future.

  22. CWMS Products

  23. Status ofData Acquisition

  24. Threshold Bars Cautionary Stage Above Flood Stage

  25. Plots Inflow Outflow

  26. Time of Forecast Time of Forecast Forecast Results Lake Elevation Inflow Outflow

  27. Impacts & Required Responses

  28. Data Dissemination

  29. Flood Inundation Mapping

  30. CWMS Applications • Real-time watershed forecasts • Water control decision support • Emergency planning and response • Project planning (new projects, alternative projects, modified regulation) • Post-event analyses (benefits) • Flood plain studies
