Final answer:
Flooding is an event in which water overflows the banks of a river channel due to heavy rainfall. Factors such as precipitation patterns, vegetation, topography, land use, and soil characteristics can affect the occurrence of flooding.
Step-by-step explanation:
Flooding is an event in which the amount of water flowing through a river channel overflows its banks. When there is heavy rainfall, the water level in the river can rise above the normal level and spill over onto the surrounding land.
This can happen when the river cannot hold the increased volume of water due to factors such as precipitation patterns, vegetation, topography, land use, and soil characteristics.
