A computer program for analyzing channel geometry
R.S. Regan, R.W. Schaffranek
1985, Water-Resources Investigations Report 85-4335
The Channel Geometry Analysis Program (CGAP) provides the capability to process, analyze, and format cross-sectional data for input to flow/transport simulation models or other computational programs. CGAP allows for a variety of cross-sectional data input formats through use of variable format specification. The program accepts data from various computer media...

Analysis of surface-water data network in Kansas for effectiveness in providing regional streamflow information
K.D. Medina, Gary D. Tasker
1985, Open-File Report 85-680
The surface water data network in Kansas was analyzed using generalized least squares regression for its effectiveness in providing regional streamflow information. The correlation and time-sampling error of the streamflow characteristic are considered in the generalized least squares method. Unregulated medium-flow, low-flow and high-flow characteristics were selected to be representative...
