The hydrologic cycle and BOD pollutant loads of all sub-watersheds were analyzed using HSPF (Hydrological Simulation Program-Fortran). At first, sensitivity analyses to water quantity (peak discharge and total volume) and quality (BOD peak concentrations and total loads) were conducted and some critical Parameters were selected. For more precise simulation, the study watershed was divided into four parts according to the landuse characteristics and used climate data and so calibrated and verified respectively. It was found that as the urban area ratio increases in the downstream direction, baseflow decreases (11.1 % $
ightarrow$ 5.0%) and the ratio of direct runoff volume(42.5 % $
ightarrow$ 56.9 %), BOD concentration (3.3 mg/L $
ightarrow$ 15.0 mg/L) and unit loads (55.4 kg/ha/year $
ightarrow$ 354.5 kg/ha/year) increase. |
