Corps Water Management System (CWMS) Modernization

Water Management Mission

• Regulate river flow from 700 Corps projects to
  provide national benefits.
• Achieve purposes specified in authorizing
  legislation.
• Multiple interests Corps officials, public,
  stakeholders, interest groups open process.
• Operation plans codified in reservoir regulation
  manuals fields bible.

3
Water Management Operations

• Hundreds of water management decisions made every
  day, nation-wide.
• Reservoir releases, power generation, structure
  operations.
• System-wide issues flood fighting,
  environmental management, partnering, public,
  etc.
• Normal conditions routine floods/ emergencies
  complex, many participants.

Corps Water Management System

• CWMS is the data acquisition, management,
  modeling and decision support system that
  supports the Corps it its water management
  mission of regulating dam and reservoir projects.
• CWMS is a nationwide integrated system of
  hardware, software, and other resources that
  acquires, analyzes, and stores data develops
  decision support information and allows user
  access to any data and information on the system.

CWMS Components

• Data Acquisition
• Flow Stage Monitoring
• Project Operating Conditions
• Weather Conditions
• Data Base
• Oracle Database Management System base
• Standard Water Control Schema Across the Corps
• Forecast Modeling
• Web-Based Data Dissemination

6
Data Base

• Time Series Data
