Question

Which of the following orientation of beds is most suitable for dam construction?

• A. beds which are faulted
• B. beds which are folded
• C. beds with gently inclined in upstream direction
• D. beds with steep upstream dip

Hint:

Upstream-dipping beds help resist seepage; gentle dip ensures safety and stability.

Answer 1

The Correct Option is C

The best orientation for dam foundations is gently inclined beds dipping upstream. This prevents water seepage under the dam and enhances structural stability by using the bedding planes as natural barriers.
