What is Floods and Flood Management?
Within Earth & Environmental Science, which covers our planet, its resources and ecosystems, and how people can protect the environment, this topic explains Floods and Flood Management. Earth and environment topics show how the planet’s systems shape landscapes, climate and life, with models that make these processes visible.
Check that you can explain Floods and Flood Management in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Floods and Flood Management helps you explain the environment around you and weigh up how people can protect it.
Floods and Flood Management in detail
Floods occur when water covers normally dry land, caused by heavy rainfall, rapid snowmelt, rivers overflowing, storm surges or dam failure. They are made worse by saturated or impermeable ground, deforestation, urbanisation and building on floodplains. Flash floods happen suddenly.
Impacts include loss of life, damaged property, disruption and disease, though floods also deposit fertile silt. Management includes hard engineering (dams, levees, flood walls, channel straightening) and soft engineering (floodplain zoning, wetland restoration, planting trees, natural flood management, warnings and sustainable drainage). Climate change is increasing the risk in many areas, so a mix of approaches is used.
