HSPF-Paddy모형을 이용한 새만금 유역의 수문/수질 모델링 = HSPF-Paddy Modeling of water flow and water quality in Seamangeum watershed

다국어 초록 (Multilingual Abstract)

Computer simulation models are the most powerful tools for this purpose and can be applied to answer a variety of questions, support watershed planning analysis, and develop TMDL (total maximum daily load). Applicability of a widely accepted watershed-based water quality assessment tool (BASINS) and its associated watershed model Hydrologic Simulation Program - Fortran (HSPF-Paddy) was evaluated on the Saemangeum watershed. Calibration result of HSPF-Paddy was satisfactory water quality and flow also reasonably matched the observed data. It was demonstrated that calibration with dry-day data in relatively long period might be adequate to simulate hydrologic characteristic and water quality of the watershed in HSPF, and using parameters generated in BASINS for nonpoint source pollution simulation is suggested when enough wet-day monitoring data are not available. Overall, BASINS/HSPF-Paddy was applicable and found to be a powerful tool in pollutant loading estimate form watershed, and its use in TMDL is recommended.
