  2. 2. INTRODUCTION : A flood is an overflow of water, a deluge of water that submerges land which is normally dry. A flood occurs when water overflows or inundates land that's normally dry. This can happen in a multitude of ways. Most common is when rivers or streams overflow their banks. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway.
