Abstract
A model based on de Sant-Venant equations for dynamic flow in open channels was calibrated and verified for a 0.75-mile urbanized reach of Spring Brook, a tributary to the West Branch Du Page River. The model was used to simulate flow in the reach, which passes through two short culverts, one with overbank flow during periods of high flow. Stage and discharge data were collected at 10 sites with the study reach during three high-flow periods. Simulated stages and discharges were compared graphically to field-collected data. Errors in simulated stage and discharge were small except when debris, not represented in the model, clogged the culvert.
