- River Management: Hard Engineering
- Dam Construction
- Built along course of river to control discharge. Water is held back by the dam and released in a controlled way.
- Water usually stored in resevoir behind dam. Can be used for hydroelectric power.
- Very expensive.
- Sediment often trapped behind wall of dam, causing further erosion downstream.
- Settlements/ agricultural land may be lost when the river valley is flooded to form a reservoir.
- River Engineering
- River may be widened / deepened to carry more water. May be straightened so water can travel faster.
- Channel of course can also be altered, diverting floodwaters away from settlements.
- Altering the river channel may lead to greater risk of flooding downstream, as the water is carried there faster.
