매개변수 보정 전문가시스템을 이용한 HSPF 모형의 수문 매개변수 보정 및 적용성 평가

Abstract

The purpose of this study was to evaluate the applicability of the HSPEXP expert system for the calibration of the HydrologicalSimulation Program - Fortran (HSPF) for the study watershed. HSPEXP offers advice to the modeler, suggesting parameter changesthat might result in better representation of a river basin and provides explanations supporting the recommended parameter changes. The study watershed, Sancheong, is located within the Nakdong River Basin and having the size of 1,072.4 km2. Input data for theHSPF model were obtained from the landuse map, digital elevation map, meteorological data and others. Water flow data from 2006to 2008 were used for calibration and from 2009 to 2010 were for validation. Using the HSPEXP expert system, hydrologicalparameters were adjusted based on total volume, then low flows, storm flows, and finally seasonal flows. For the calibration andvalidation period, all the HSPEXP model performance criteria were satisfied.
