What is flooding?

A flood is an overflow of water than submerges land that is usually dry.

Flooding may occur:

  • as an overflow from water bodies, such as a river or lake, or ocean, in which the water overtops or breaks levees, resulting in water escaping its usual boundaries.
  • due to an accumulation of rainwater on saturated ground in an areal flood.

Why is it important that we manage flooding?

  • Flooding can cause significant damage to homes and businesses and can have significant social and economic impacts.
  • With climate change, flooding is predicted to increase in frequency and severity in the UK and so it is imperative that we implement proactive mitigation measures to reduce the risk of flooding in the London Borough of Hounslow.
