HYDROLOGIC MODELING, PARAMETER ESTIMATION, AND WATERSHED CHARACTERISTICS

A GENERAL WATERSHED MODEL REPRESENTS THE RUNOFF PHASE OF THE HYDROLOGIC CYCLE BY A SERIES OF MOISTURE ACCOUNTING EQUATIONS. THE STANDFORD WATERSHED MODEL USES FIXED EQUATIONS CONTAINING VARIABLE PARAMETERS WHICH ARE CALIBRATED FOR A WATERSHED BY TRIAL-AND- ERROR MATCHING OF SIMULATED TO RECORDED FLOWS. OPSET WAS DEVELOPED TO ESTIMATE THESE PARAMETERS THROUGH A COMPUTERIZED LEAST SQUARES MATCHING. THE PROCEDURE REDUCES ESTIMATING SCATTER AND PROVIDES PARAMETER ESTIMATES WHICH WERE CORRELATED WITH PHYSICAL CHARACTERISTICS OF THE WATERSHED CHANGES WITH URBANIZATION. /AUTHOR/
