2 Fauwaz Hanbali CORPS WATER MANAGEMENT Corps Water Management System (CWMS) A USACE Tool for Real-Time Decision Support for Water Management Ensures consistent operation across 36 offices Multipurpose Reservoirs, Flow Control Structures, and thousands of miles of levees and other structures. To achieve the full range of authorized purposes from all of USACE projects. NWS Forecasts CWMS Real-Time Fully Integrated Hydrologic & Hydraulic Models Streamgage Data Floods to droughts and everything in between. Operational Decisions Inundation Mapping 2
