ABSTRACT

Model assessment for discharge rate at Seo-cho pump station and discharge rate by each method draw the proper unit hydrograph. The discharge is estimated by time series analysis of elevation relationship at beginning and end time of pump operation and calculation of reservoir elevation-volume polynomial regression equation. As a result of study on the least deficiency is found at Time-Area method from each rainfall time series comparison of discharge volume. Kerby formula is more effective. Result of this study could be used for base data of runoff analysis at urban basin.
