FAQs on Water Conservation Dams and Water Harvesting Video Lecture - Class 10

1. What is the importance of water conservation dams?
Ans. Water conservation dams are important as they help in storing and managing water resources. They provide a steady supply of water for various purposes such as irrigation, drinking water, and hydropower generation. These dams also help in preventing floods by controlling the flow of water during heavy rainfall.
2. How do water conservation dams contribute to water harvesting?
Ans. Water conservation dams contribute to water harvesting by collecting and storing rainwater. When it rains, the water is collected in the reservoir behind the dam. This stored water can then be used during the dry season or droughts, ensuring a continuous supply of water for various needs.
3. What are the benefits of water harvesting?
Ans. Water harvesting has several benefits. Firstly, it helps in conserving water by capturing and storing rainwater, which can then be used for various purposes. This reduces the reliance on groundwater and surface water sources. Additionally, water harvesting helps in recharging groundwater levels, preventing soil erosion, and supporting agricultural activities during dry spells.
4. How can individuals contribute to water conservation through water harvesting?
Ans. Individuals can contribute to water conservation through water harvesting by implementing rainwater harvesting systems in their homes. This can be done by collecting rainwater from rooftops and directing it into storage tanks or underground wells. By doing so, individuals can reduce their reliance on municipal water supply and help in conserving water resources.
5. Are there any disadvantages of water conservation dams and water harvesting?
Ans. While water conservation dams and water harvesting have numerous benefits, there can be some disadvantages as well. Constructing dams may lead to displacement of local communities and loss of natural habitats. It can also alter the natural flow of rivers, impacting the ecosystem. Similarly, water harvesting may require initial investment and maintenance costs, and the effectiveness may vary depending on the rainfall patterns in a particular region.
