5.1. Defining Uniform Depth Flow

Try these first

1. 1.

   What is uniform depth flow?

   Hint

   Think about water flow in a canal.

2. 2.

   What does y₀ represent?

   Hint

   What does normal mean in everyday usage?

3. 3.

   What is uniform depth flow?

   • Variable flow depth
   • Constant flow depth
   • Decreasing flow depth

   Hint

   Think about the meaning of uniform.

4. 4.

   True or False: Normal depth is represented by y₀.

   • True
   • False

   Hint

   What does 'normal' suggest in terms of stability?

5. 5.

   A channel designed for uniform flow experiences a sudden increase in width. How would this impact the depth and what adjustments would you suggest?

   Hint

   Consider continuity and what happens when channels change size.

6. 6.

   Compare the effects of increasing channel slope versus decreasing depth on the fluid flow velocity in a uniform flow condition.

   Hint

   Relate it to energy considerations in open channel flow.
