Abstract

The objective of this study is to investigate the effects of infiltration wells on flood peak reduction and flood frequency. The analysis was carried out with the use of a stochastic rainfall model incorporating a within-storm rainfall distribution of low, medium and high variability. This study was motivated by flooding in a catchment in Indonesia, which is potentially affected by land use changes. The parameterisation of the climate and landscapes was derived from a specific catchment in Indonesia. An analysis of land use changes underlines the importance of green land in reducing flood peaks. With city development, however, land is converted for settlements, industries and trade areas, which will increase flood peaks significantly. An analysis on the use of infiltration wells shows that flood peak reduction of up to 50% compared to without wells. The results also demonstrate that within-storm rainfall distribution affects flood peaks, where the effects of infiltration wells in reducing flood peaks are more observable when incorporating low within-storm variability.
