Abstract:

Statistical precipitation models used as input to conceptual hydrologic models, offer an alternative mechanism for simulating streamflow. In sparsely gauged catchments, or areas where gauging has been discontinued, precipitation simulation can extend short or imcomplete gauge records. Twenty years of mean areal precipitation data for 6 hour intervals are analyzed, and a stochastic model of mean areal precipitation is constructed for the North Branch, Potomac River. Simulated mean areal precipitation is used as input to the Sacremento Soil Moisture Accounting model to simulate streamflows. Statistics for simulated streamflow and streamflow produced using historical precipitation are compared to asses the representativeness of simulated precipitation.
