Channel Geometry Analysis Program (CGAP)
Entry ID: USGS_CGAP


Summary
Abstract: The Channel Geometry Analysis Program (CGAP) permits the analysis, interpretation, and quantification of the physical properties of an open-channel reach as defined by a sequence of cross sections. The primary function of the program is to compute the area, width, wetted perimeter, and hydraulic radius of cross sections at successive increments of water-surface elevation (stage) from data that ...
