This chapter explores the concepts related to flooding and flood mitigation. With rapid urbanization and the prevailing threat of climate change all around us, the frequency of natural and man- made disasters such as floods are on the rise. Flooding is an overflowing of water onto land that is normally dry. Floods may occur due to heavy rains, when ocean waves come onto shores, the melting of slow or the breaking of dams. Flooding can happen due to various reasons, such as, the state of the ground, drainage, geology, relief, vegetation, catchment shape, land use, catchment size and the attempts at management.

The risks of flooding are further magnified due to human factors such as buildings and mindless deforestation which leaves a hydrological impact due to urbanization. The student will be able to understand the effects of deforestation. The chapter in conclusion talks about the need to preserve the forests around us and emphasizes the need to plan flood mitigation methods in advance to minimize damage. The chapter also discusses ways to improve flood warning via a variety of methods that include telemetry, live data among the others.
