Flooded river is an example of `"____"`

Options

A. streamline flow
B. turbulent flow
C. laminar flow
D. viscos flow

Answer

To answer the question, "Flooded river is an example of '____'", we need to analyze the characteristics of the flow in a flooded river.

### Step-by-Step Solution:

1. **Understanding River Flow**:
- A river's flow can be categorized into two main types: laminar flow and turbulent flow.

2. **Defining Laminar Flow**:
- In laminar flow, the fluid moves in parallel layers, with minimal mixing between them. The flow is smooth and orderly, with each layer sliding past the others without disruption.

3. **Defining Turbulent Flow**:
- In turbulent flow, the fluid experiences chaotic changes in pressure and flow velocity. The flow is irregular and mixed, with eddies and swirls present. This type of flow is characterized by high velocity and significant mixing of fluid layers.

4. **Analyzing a Flooded River**:
- During flooding, rivers typically experience increased flow rates and chaotic water movement. The water does not flow in smooth layers but rather mixes vigorously, leading to unpredictable patterns.

5. **Conclusion**:
- Based on the characteristics of the flow in a flooded river, we can conclude that it is an example of "turbulent flow".

### Final Answer:
Flooded river is an example of **turbulent flow**.
