The Soil Conservation Service (SCS) has revised its mainframe water surface profile model WSP2 and is distributing it as a microcomputer program. WSP2 is used by SCS and others in flood plain management studies and project planning. The model uses the standard step method for computing one-dimensional steady flow profiles for channel and flood plain cross sections and computes backwater at bridges and culverts.

Unique features of WSP2 are described with respect to input data, calculation procedures, user manual, error checking, and output. The use of WSP2 with other SCS hydrologic software is described.
