==Riverine Flooding==

Urbanization increases impervious surfaces and the increased impervious surface will result in an increase in runoff, as a result the flows exceed the capacity of the receiving downstream section of river and this may cause flooding.

''“Hydrological changes associated with urbanisation are increased storm runoff volumes and peak flows (Qp), faster flow velocities and shorter time of concentrations. A reduction in infiltration generally leads to less groundwater recharge and baseflow.The flashy response results in tremendous stresses for the urban stream and downstream receiving areas (Walsh et al., 2005)."''
