This study developed a general method for estimating runoff rates and associated confidence limits of a given recurrence interval for ungaged small urban watersheds. The utility of the method developed was demonstrated through its application to a southeast region of Texas. Some 200 historical rainfall-runoff events from 40 watersheds in the Houston, Austin, Dallas, and Fort Worth urban areas were analyzed. Watershed data such as drainage area, percent of urbanized area channel length, average channel slope, land slope, and soil type are documented. Total rainfall amounts, intensities, durations, and mass-time distributions were determined for each storm and used to develop …
