Abstract
A consistent pattern has been evaluated in which the width, depth, and velocity of flow in a stream change along the course of the stream with a constant frequency of discharge. These channel characteristics are termed hydraulic geometry and constitute an interdependent system which is described by a series of graphs having simple form, or by equations. The data from 166 stream gaging stations in Illinois have been assembled and used to develop the parameters to define the hydraulic geometry of these streams. Results are presented as separate sets of equations for 18 river basins in Illinois. Stream characteristics are related to frequency of discharge and to drainage area as independent variables. Stream velocities computed from hydraulic geometry equations check favorably with actual stream velocities measured by time-of travel in streams determined by using dye tracers. These equations are used to predict the average depth and velocity of flow at problem locations on the stream where no measurements are available. This allows computation of the reoxygenation capacity of the stream at the problem location, and will be valuable for many purposes in water resources development.
