Abstract

Synthetic hydrographs are often used in stormwater management to provide estimates of peak rate, volume and time distribution of stormwater runoff. A hydrograph model based on the mathematical technique of convolution was developed using an exponential routing response function and the basic watershed continuity equation. After incorporating the model into a computer program, it was calibrated using hydrographs from four urban and three rural watersheds. The watersheds are located in regions of west and south Florida and range in size from 14.7 to 3500 acres. Two other hydrograph models, the Soil Conservation Service's Unit Hydrograph (SCS-UH) mode 1 and the Santa Barbara Urban Hydrograph (SBUH) model were also calibrated so that an unbiased comparison of the models could be made. The results of a graphical comparison and a sum of squared error analysis indicate that, for the seven watersheds involved, the continuous convolution model produces a more accurate hydrograph than the SBUH model between 71.1 and 93.4 percent of the time. Continuous convolution also provides more accurate results when compared to the SCS-UH model between 93.5 and 100 percent of the time.
