Abstract

Infoworks has remarkable ability in predicting runoff from urbanized area through stormwater drainage network. Here, by changing three land surface hydrological parameters such as surface runoff ratio, routing value and initial loss, runoff from agriculture dominated area (basically agricultural area but includes some paved area and drainage systems) was predicted. Effects of each parameter on the predicted runoff during2 rainfall events observed in Sendai were discussed. Runoff ratio which designates ratio of the surface runoff volume against total rainfall volume on given land use pattern was always most sensitive in predicting runoff. Routing value which designates speed of runoff water till entering the drainage system showed detectable effects on drainage profiles. Initial loss which designates the volume of water not contributing to runoff by retaining rainfall water at the surface was not significant on drainage profiles at the peak discharge. These results underline the high possibility of predicting runoff from agriculture dominated area using Infoworks.
