AbstractThe water budget of Sonoita Creek watershed has been estimated on a monthly and annual basis but not for individual storm events. An attempt is made here to predict surface runoff from individual storm events. Because of the many factors that affect storm discharge and the spatial heterogeneity of the watershed and the storm events, a distributed model is applied to estimate event runoff. KINEROS2, a model developed at a similar watershed, was selected for this task. The paucity of historical data was a major complication during model calibration. A method was developed to estimate the return period of the events on record. The estimated event return periods were then used with published rainfall frequency data to determine the duration of the historical precipitation events. Once calibrated, the model was put to use to forecast discharge in the creek at three locations from storms of various depths, intensities, and locations.
