The purpose of this study was to test the applicability of the HSPEXP model performance criteria for calibrating hydrologic parameters of HSPF. Baran watershed, located at Whasung city, was selected as a study watershed in this study. Input data for the HSPF model were obtained from the digital elevation map, landuse map, soil map and others. Water flow data from 1996 to 2000 was used for calibration and from 2002 to 2007 was for validation. Using the HSPEXP decision-support software, hydrology parameters were adjusted based on total volume, then low flows, storm flows, and finally seasonal flows. Suggested criteria for each model performance variables were referenced from the previous research. For the calibration period, all the HSPEXP model performance criteria were satisfied while two criteria were slightly violated for the validation period.

The purpose of this study was to evaluate the applicability of the HSPEXP expert system for the calibration of the Hydrological Simulation Program - Fortran (HSPF) for the study watershed. HSPEXP offers advice to the modeler, suggesting parameter changes that 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 $1,072.4km^2$. Input data for the HSPF model were obtained from the landuse map, digital elevation map, meteorological data and others. Water flow data from 2006 to 2008 were used for calibration and from 2009 to 2010 were for validation. Using the HSPEXP expert system, hydrological parameters were adjusted based on total volume, then low flows, storm flows, and finally seasonal flows. For the calibration and validation period, all the HSPEXP model performance criteria were satisfied.

HSPF 모형은 수문, 유사, 영양물질, 대장균, 농약 등 다양한 성분 모의할 수 있는 준분포형의 개념적 모형으로 미국 환경청에 의해 개발되었다. 본 연구에서는 HSPF 모형의 수문 매개변수를 보정하기 위하여 HSPF 모형의 보정을 위한 전문가 시스템인 HSPEXP를 이용하였다. HSPF 모형의 수문인자의 초기치는 BASINS의 기술노트 6에 있는 가이드라인을 이용하여 추정되었다. 시험유역에 대한 초기치는 주어진 매개변수의 범위 내에서 보정되었다. 시험유역은 경기도 화성시에 있는 발안HP#6 유역의 자료를 이용하였으며 1996년부터 2007년까지의 자료가 이용되었다.
