Abstract :
[en] This work consisted in the modelling of the rainfall-runoff relationships in the Upper Bukit Timah catchment in Singapore, in order to highlight the impacts of urbanisation on hydrology. The SWMM model, a one-dimensional physically based model especially developed for urban areas, was mainly used. The parameters encoded into the model were determined by different means and several methods were used for their determination in order to assess their influence on the modelling.Using the final adjustment of the SWMM model, a diachronic analysis was performed in order to present the effects of urbanisation on runoff.
