  1. US Army Corps of Engineers Corps Water Management System (CWMS) & Upper Rio Grande Water Operations Model (URGWOM) Water Information Management Systems & Water Availability Workshop September 14, 2006

  2. Introductions • Roberta Ball, PE – Civil Engineer • Dennis E. Garcia, PE – Civil Engineer • Reservoir Control Branch – Albuquerque • Presentation Topics: • General CWMS Information • CWMS Implementation in Albuquerque • CWMS and URGWOM

  3. Perspective • Corps regulates 700 reservoirs nationwide • Real-time water control 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. From Data to Water Control Decisions SERVERS Weather Forecast Data Processing Data Storage Modeling Observed Data Public and Cooperators Field Office Instructions Water Control Decisions

  5. CWMS • An integrated system of hardware, software, and communication resources supporting Corps’ real-time water control mission. • Developed by the Corps Hydrologic Engineering Center (HEC). • Corps-wide Enterprise Managed System.

  6. Components on Central Computers Servers

  7. Components on User PC Clients

  8. Data Acquisition

  9. Data Acquisition • Real-time data - observed stream flow, precipitation, temperature, water quality, gate settings, reservoir levels, etc. • Field observations • Weather forecasts

  10. Data Acquisition

  11. Data Validation

  12. Data Storage

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

  14. User Control and Visualization Interface

  15. Control & Visualization Interface - CAVI • Client – Server • User Interface • Control server processes • View data – observed & modeled

  16. Data Visualization

  17. Data Dissemination

  18. Data Dissemination • Common information source • Data & information placed on Web-based platform Available to Corps users & outside interests Real-time availability • Extend to data exchange

  19. CWMS Components Data Base Data Collection Modeling Information dissemination Data Visualization

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

  21. Modeling

  22. Gridded Runoff Analysis/Spatially Distributed Hydrologic Modeling Precipitation is processed on a grid basis HEC-GeoHMS

  23. HEC-HMS - Hydrologic Modeling System • Computes streamflow throughout a river basin given precipitation (such as NexRad radar rainfall) and watershed runoff characteristics.

  24. HEC-ResSim – Reservoir Simulation • Simulates reservoirs’ operations throughout a river basin given streamflows and operating rules for at-site and downstream water flow requirements.

  25. HEC-RAS – River Analysis System • Computes river velocities, stages, and inundated areas given streamflow and river/floodplain geometry, and hydraulic characteristics.

  26. HEC-FIA – Flow Impact Analysis • Computes damages to structures and other contents of the floodplain, given river stages and damage relationships. Assesses damages & benefits based on river stage

  27. Real-Time Forecast I see flooding in your future.

  28. HEC-HMS computes forecasted flows from: Observed precipitation from NEXRAD and rain gages. Future precipitation forecasts and scenarios. Observed flow. HEC-ResSim simulates reservoir operations and downstream flows from HEC-HMS flows. HEC-RAS computes stages and inundation areas from ResSim flows. FIA computes damages and impacts from HEC-RAS stages or ResSim flows. Inundation areas and depths are displayed in CorpsView, an extension to ARC. CWMSModel Linking

  29. CWMS Albuquerque

  30. CWMS Modeling Status • Arkansas River Basin First watershed Hydrologic Model Reservoir Operations Model Future: • Snowmelt runoff model • Flood inundation model ? • Flood impact model ?

  31. CWMS Modeling Status • Pecos River Basin Hydrologic Model Reservoir Operations Models • Under development • Testing alternate models Future: Snowmelt runoff model • Flood inundation model ? • Flood impact model ?

  32. CWMS Modeling Status • San Juan River Basin Hydrologic model - • under development Future: • Reservoir Operations Model • Snowmelt runoff model • Flood inundation model ? • Flood impact model ?

  33. CWMS Modeling Status • Canadian River Basin Hydrologic Model Future: • Reservoir Operations Model • Snowmelt runoff model • Flood inundation model ? • Flood impact model ?

  34. CWMS Modeling Status • Rio Grande Basin Hydrologic Model – under development Reservoir Simulation - • Integrate URGWOM Future: • Snowmelt runoff model • Flood inundation model ? • Flood impact model ?

  35. URGWOM & CWMS • URGWOM predates CWMS • URGWOM has support structure to get the output of one model to the next • Duplicated on Corps and USBR systems • URGWOM – reservoir operations Accounting model – observed conditions Forecast model – future flows Water Operations model – reservoir operations

  36. Current CWMS-URGWOM Connection Data Storage Data Collection URGWOM Modeling Information dissemination Data Visualization

  37. Future - Integrate RiverWare RiverWare

  38. CWMS & RiverWare • Funded by several Corps offices • Still under development • RiverWare – native support for HEC-DSS files • CWMS CAVI – interface with RiverWare

  39. RiverWare & HEC-DSS • CADSWES effort • Funded by Corps and USBR • Available in current version • Designed to support other future data sources

  40. CWMS & RiverWare • HEC effort • Under development • Design to support other future modeling software

  41. URGWOM & CWMS • Integration plan • USBR – CWMS-less configuration • Implement new RiverWare HEC-DSS interface • CWMS version – focus on real-time forecasts

  42.
