3.1.2. Spillways and Energy Dissipators

Try these first

1. 1.

   What is a spillway?

   Hint

   Think of how water passes in a controlled manner.

2. 2.

   What does energy dissipation refer to?

   Hint

   Consider how we make a fast flow slower.

3. 3.

   What is the primary purpose of a spillway?

   • To store water
   • To allow controlled water release
   • To divert rivers

   Hint

   Think about how dams manage water levels.

4. 4.

   True or False: Energy dissipators are not necessary for spillway design.

   • True
   • False

   Hint

   Consider safety for people and nature.

5. 5.

   Consider a reservoir with a peak discharge estimate of 500 m³/s. Design a simple spillway that can handle this discharge. Discuss the features you would include.

   Hint

   Think about flow area and safety features.

6. 6.

   If erosion occurs 100m downstream of a spillway due to high-velocity water, analyze potential design changes to mitigate this issue.

   Hint

   Consider how to slow down the water effectively.
