Abstract: The Clark County Regional Flood Control District, which includes the Las Vegas, Nevada metropolitan area, has recently adopted hydrologic criteria which are intended to standardize the approach to the preparation of hydrologic models. The District is also establishing a network of stream and rain gauges within the Las Vegas valley. To verify the reliability of the adopted criteria to predict runoff, a recorded rainfall event was simulated with a model developed using the criteria. Based on this limited verification effort, it appears that the methodology reliably predicts peak runoff but not runoff volume.
