Fulford, J.M., 1994, User's guide to SAC, a computer program for computing discharge by the slope-area method: U.S. Geological Survey Open-File Report 94-360, 31 p.
SAC follows USGS standardized procedure for computing discharge by the slope-area method. The source is written in Fortran 77.
The program solves the 1-D steady-state energy and continuity equations for discharge given upstream and downstream water-surface elevations.
Cross-section geometry and roughness values that describe the channel reach geometry along with measurements of high water marks.
Text output of discharges and other variables used in the computations.
