The correct Answer is:
To solve the question about the importance of making check dams across flooded gullies, we will analyze each option provided and determine which ones are true based on the functions of check dams. ### Step-by-Step Solution: 1. **Understanding Check Dams**: - Check dams are small barriers built across gullies or streams to slow down water flow and capture sediment. They help in water conservation and soil management. 2. **Analyzing Option (i)**: - **Hold water for irrigation**: While check dams can store water, their primary purpose is not specifically for irrigation. They are more focused on water conservation and preventing erosion. - **Conclusion**: This option is not entirely correct. 3. **Analyzing Option (ii)**: - **Hold water and prevent soil erosion**: Check dams do hold water and are effective in reducing soil erosion by slowing down the water flow, which allows sediment to settle. - **Conclusion**: This option is correct. 4. **Analyzing Option (iii)**: - **Recharge groundwater**: Check dams facilitate groundwater recharge by allowing water to percolate into the ground, thus replenishing aquifers. - **Conclusion**: This option is correct. 5. **Analyzing Option (iv)**: - **Hold water permanently**: Check dams do not hold water permanently; they are designed to temporarily store water and allow it to seep into the ground or flow downstream after a certain period. - **Conclusion**: This option is not correct. 6. **Final Conclusion**: - Based on the analysis, the correct answers are options (ii) and (iii). Therefore, it is important to make check dams across flooded gullies because they hold water and prevent soil erosion, and they recharge groundwater. ### Final Answer: The correct options are: - (ii) hold water and prevent soil erosion - (iii) recharge groundwater
