SAC - Slope-Area Computation Program

VERSION/DATE: Version 97-01 1997/05/01

OPERATING SYSTEM: DOS

DISTRIBUTOR: USGS

DOCUMENTATION (43 Pages):

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.

ABSTRACT

SAC follows USGS standardized procedure for computing discharge by the slope-area method. The source is written in Fortran 77.

METHOD

The program solves the 1-D steady-state energy and continuity equations for discharge given upstream and downstream water-surface elevations.

DATA REQUIREMENTS

Cross-section geometry and roughness values that describe the channel reach geometry along with measurements of high water marks.

OUTPUT OPTIONS

Text output of discharges and other variables used in the computations.
