Description:
Dams are engineered structures built across a river that regulate and control river flow. They are used to regulate floods and store water for supply.
Advantages:
- Regulates flow
- Stores water supplies
- Allows irrigation
- Generates electricity
- Prevents flooding
- Allows for recreation
Disadvantages:
- High costs - Floods land upstream, and may displace population and habitats
- Causes problems downstream - Less sediment and water flow, clearwater erosion, causes environmental change
