Regression equations are presented for predicting parameters in the geomorphic equations that relate Streamflow discharge at a site to channel width and cross‐sectional area (from which velocity and hydraulic depth can be determined). Two measures are used in these regression equations, drainage area and channel slope, both of which are obtained from topographic maps. Regeneration and simulation tests at stream gage sites located in the Cumberland Plateau Physiographic Province indicate that at higher flows this system of equations can predict width and area within ∼25% about ⅔ of the time. These results appear to be comparable with or better than results that would normally be obtained from the reconnaissance field surveys normally used in Streamflow routing for planning‐level applications.
