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
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
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
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
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.
Components on Central Computers Servers
Components on User PC Clients
Data Acquisition • Real-time data - observed stream flow, precipitation, temperature, water quality, gate settings, reservoir levels, etc. • Field observations • Weather forecasts
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
Control & Visualization Interface - CAVI • Client – Server • User Interface • Control server processes • View data – observed & modeled
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

Gridded Runoff Analysis/Spatially Distributed Hydrologic Modeling Precipitation is processed on a grid basis HEC-GeoHMS
HEC-HMS - Hydrologic Modeling System • Computes streamflow throughout a river basin given precipitation (such as NexRad radar rainfall) and watershed runoff characteristics.
HEC-ResSim – Reservoir Simulation • Simulates reservoirs’ operations throughout a river basin given streamflows and operating rules for at-site and downstream water flow requirements.
HEC-RAS – River Analysis System • Computes river velocities, stages, and inundated areas given streamflow and river/floodplain geometry, and hydraulic characteristics.
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
Real-Time Forecast I see flooding in your future.
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
