Correct Answer - Option 1 : Solid gravity dam
Concept:
Gravity dam
A gravity dam has been defined as a structure that is designed in such a way that its own weight resists external forces.
- A low gravity dam is one whose height is less than Hmax.
- A high gravity dam is one whose height is greater than Hmax.
- A gravity dam is called a low dam if the base width is designed from the consideration of the resultant falling as close as possible to the extremities of the middle third of the base.
