초록
This research presents an streamflow modeling approach in a data-scarce estuary reservoir watershed which has been suffered from high salinity irrigationwater problem after completion of land reclamation project in South Korea. Since limited hydrology data was available on the Iwon estuary reservoirwatershed, water balance relation of the reservoir was used to estimate runoff from upstream of the reservoir. Water balance components in the reservoirconsists precipitation, inflow from upstream, discharge through sluice, and evaporation. Estimated daily inflow data, which is stream discharge fromupstream, shows a good consistency with the observed water level data in the reservoir in terms of EI (0.93) and R2 (0.94), and were used as observed flowdata for the streamflow modeling. HSPF (Hydrological Simulation Program - Fortran) was used to simulate hydrologic response of upstream of thereservoir. The model was calibrated and validated for the periods of 2006 to 2007 and 2008 to 2009, respectively, showing that values of EI and R2 were0.89 and 0.91 for calibration period, 0.71 and 0.84 for validation period.
