7. Summary

Try these first

1. 1.

   What is the primary material used in Earthfill dams?

   Hint

   Think about what materials are commonly found in nature.

2. 2.

   Which type of dam utilizes its weight to resist water pressure?

   Hint

   Consider how heavy objects help resist forces.

3. 3.

   Which type of dam uses earth materials primarily?

   • Gravity Dam
   • Embankment Dam
   • Arch Dam

   Hint

   Look for the type that is flexible and built from soil.

4. 4.

   True or False: Arch dams are designed to transmit loads to their abutments using arch action.

   • True
   • False

   Hint

   Think about the shape of the dam.

5. 5.

   Design a theoretical dam for a valley with a known flow rate. Discuss which type of dam would be optimal and justify your choices based on site conditions.

   Hint

   Analyze the features of the valley and flow rates to find the most suitable dam type.

6. 6.

   Evaluate the consequences of not implementing seepage control in dam construction. Discuss potential failure modes and their impacts.

   Hint

   Consider the effects of water pressure on the structure and downstream communities.
