Abstract: Increase in urbanization leading to climate changes and human activities have resulted in flash flood scenarios with varying intensity rainfalls in the city. The uneven distribution of rain fall coupled with Mindless urbanization, encroaching upon and filling up of natural drainage channels and lakes to use the high-value urban land for buildings are the main causes of urban flooding. The built environment of urban areas transforms the natural pervious environment into impervious ground surfaces, inhibiting infiltration. Since water cannot infiltrate into the ground in these urban impervious surfaces, it runs across the surface when it rains and as the surfaces become larger and steeper the speed and quantity of runoff increases.
