The change in the land use pattern due to rapid urbanization adversely affects the hydrological processes in a catchment, leading to a deteriorating water environment. The increase in impervious areas disrupts the natural water balance. Reduced infiltration increases runoff and leads to higher flood peaks and volumes even for short duration low intensity rainfall. Due to their destructive effects, floods can significantly increase the expenses on mitigation efforts. The present study focuses on the Thirusoolam sub watershed, an urban watershed in Chennai.
