A Study of Characteristics of Flood in Urban Small River

Abstract

In this paper, the time-space characteristics of the runoff system in small urban river basins is made clear, using well-observed rainfall and water level data. In urbanized area where sewer system are complete equipped, rainfall-runoff relation is extremely direct. In other words, the rainfall is collected into the rivers so efficiently that the flood in the downstream would rise rapidly. Future application, of the gained knowledge, in urban rainfall drainage management is also examined in this study.
