Questions & Answers

Q: What factors should be considered for selecting a site for a reserved oil?

Factors such as geological conditions, leakage resistance, suitable dam foundations, cost considerations, topography, deep reservoirs, silt exclusion, and water quality should be considered.

Q: Why is minimizing leakage important for a reservoir site?

Minimizing leakage ensures the maximum volume of water can be stored in the reservoir. If the site has porous rocks or cracks, the tightness of the reservoir can be compromised, leading to reduced water levels and potential failure.

Q: How does dam foundation affect the selection of a site?

A proper dam foundation is essential to prevent percolation and uplift pressure on the dam. If the foundation is porous, water can percolate through it, leading to potential failure and safety risks.

Q: Why is the topography of the reservoir site important?

The topography should have adequate capacity without excessive land submergence. Choosing a site with a deep reservoir can reduce costs, minimize evaporation losses, and lower the likelihood of landslides.

Summary & Key Takeaways

• Geological conditions should minimize percolation losses and maximize runoff for efficient water storage in the reservoir.

• The reservoir site should have minimal leakage, and highly permeable rocks should be avoided to maintain the tightness of the reservoir.

• Suitable dam foundations are crucial for preventing percolation and uplift pressure on the dam, ensuring its stability.

• The reservoir site should have a narrow opening to minimize the dam's length for cost-effectiveness.

• Cost considerations, including real estate and compensation, should be minimized.

• The topography should have adequate capacity without excessive land submergence.

• Deep reservoirs are preferred for lower land cost, reduced evaporation losses, and decreased likelihood of landslides.

• The site should exclude tributaries carrying high silt content to maintain the water's quality.
