| A daily runoff system was constructed to support decision making for water use in the downstream region of multipurpose dams in the Han River. The daily runoff system used the modified model from NWSRFS by Tabios III et al.(1986), and potential evapotranspirationwas computed from Penman equation. DWOPER was used for channel routing. While the North Han River is the main river reach in the channel routing system, the South Han River and the Soyang River became tributaries. The rainfall-runoff model was calibrated and verified for five subvbasins. Daily runoffs were simulated with hydrometeorological data in 1986 and 1990. The simulations were performed from April to November, and the sum of computed dams. It showed the average absolute errors of 8.7¡31.6%. The sun of total discharges were simulation from April to August in 1986, the errors kept under 0.2m since September. In the simulation for 1990, we compared two simulation results. One is produced from real internal boundary conditions fixed arbitrarily. The two cases showed similar results. |
