2.2. Wave Observation from Different Perspectives

Try these first

1. 1.

   What is open channel flow?

   Hint

   Think of it like a river or a canal.

2. 2.

   What distinguishes steady flow from unsteady flow?

   Hint

   Consider what happens to the water flow during a flood.

3. 3.

   What type of flow has a consistent depth over time?

   • A) Unsteady Flow
   • B) Steady Flow
   • C) Variable Flow

   Hint

   Think about a river that flows consistently without changes.

4. 4.

   Is turbulent flow characterized by a Reynolds number greater than 12,500?

   • True
   • False

   Hint

   Recall the classification ranges provided in the lecture.

5. 5.

   A channel has a water velocity of 2 m/s and a depth of 1 m. Determine if the flow is supercritical or subcritical using Froude number.

   Hint

   Compare Fr against 1 to determine flow type.

6. 6.

   Describe the impact of a rapidly varied flow in a river setup.

   Hint

   Consider biodiversity's dependence on flow consistency.
