Name 3 hard engineering ways that prevent flooding
- Dams
- Flood walls
- Dredging
What is a dam
Large physical barriers that control the flow of the water
What is a floodwall
A large wall like structure built on the river bank to stop flooding
What is dredging
This is where the bottom of the river is dug out, which creates more room for the water
Name 4 soft engineering processes that stop river flooding
- Afforestation
- Land use zoning
- Warning systems
- Do nothing
What is afforestation
Where trees are planted to absorb the rain, which prevents flooding
What is land use zoning
areas that often flood are highlighted and not built on
What is warning systems
Building alarms and warning systems so people can prepare
What is longshore drift
The movement of material along the beach
