Step 1
The impact of dams on river processes
Answer
Dams significantly alter river processes by regulating flow and sediment transport. They create reservoirs that change the natural sediment distribution and can lead to sediment starvation downstream.
Additionally, the construction of dams can change local ecosystems, affecting fish migration and plant life due to altered water levels and temperatures. As a result, while dams can aid in flood control and water supply, they also disrupt the natural processes of the river, leading to various ecological impacts.
