1 Study the case study below on impact of dams answer the questions that follows

Here are the answers to your questions about dams:

3.1.1 The importance of dams to people is primarily for storing and providing water for domestic use, agriculture, and industries. They are also crucial for generating hydroelectric power.

3.1.2 Two advantages of building dams are:

• They store and supply water for various human needs, including drinking, irrigation in agriculture, and industrial processes.
• They are used to generate hydroelectric power, which is a renewable source of electricity.

3.1.3 Dams have several impacts on the physical environment. They cause changes in natural water flow, altering river regimes downstream. They also affect sediment transport, leading to sediment accumulation behind the dam and reduced sediment flow downstream, which can impact riverbeds and coastal areas. Furthermore, dams can alter water quality and disrupt the natural processes of river ecosystems, affecting fish and wildlife populations.
