Abstract

Urbanization has increased population and property of the urban area and runoff volumes. In addition, the number of short time concentrated local rainfall is increased by climate change (Yazdi et al., 2016). For many of these reasons, urban flooding occurs more than before, the total flood damages also increase. Structural measures such as pump station, sewer network and reservoir directly reduce the risk of flood through structure. However, structural measures need a lot of spaces and construction cost to improve flood mitigation capacity, non-structural measures become important study topic to construct efficient urban drainage system without additional structural installation. In this study, new inland-river system considering the water level of monitoring node and predicted urban stream inflow is proposed as one of the non-structural measures. The proposed inland-river system shows the flood mitigation effect of 42.07% when compared with the current urban drainage system at the 2010 rainfall data.
