The Corps Water Management System (CWMS) includes four interrelated models to assist with water management for the basin:

- GeoHMS (Geospatial Hydrologic Modeling Extension)
- ResSIM (Reservoir System Simulation)
- RAS (River Analysis System)
- FIA (Flood Impact Analysis)

The White River Basin contains 27,818 square miles: about 38 percent is in Missouri and 62 percent is in Arkansas. The fan-shaped basin is about 250 miles long in a northerly direction and varies in width from 210 miles near the Missouri-Arkansas State line to about 50 miles near the mouth of the river. Approximately three-fourths of the basin is in the Ozark highlands where the topography consists of rough dissected plateaus rugged hills, and rolling woodland. The eastern escarpment of the Ozark Mountains extends southwestward across the basin from the vicinity of Poplar Bluff, MO; along the west side of the Black River to Batesville, AR, on the White River; and thence to the vicinity of Searcy, AR, in the little Red River Basin. East of the escarpment, the basin lies in the flat terrain of the Gulf Coastal Plain. The eastern watershed divide between the White and St. Francis Rivers is formed by Crowley’s’ Ridge, which extends in a north-south direction and rises about 150 feet above the floodplain.
