Recurrence of floods in the plains of North India is due to excessive

Options

A. Siltation of dams
B. Rainfall
C. Agriculture
D. Deforestation in catchment area

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the reasons behind the recurrence of floods in the plains of North India.

2. **Identifying Possible Causes**: Consider various factors that could contribute to flooding, such as excessive rainfall, deforestation, agricultural practices, and the construction of dams.

3. **Analyzing Deforestation**: Deforestation is the removal of trees, which plays a significant role in the hydrological cycle. Trees help in absorbing rainfall and reducing surface runoff.

4. **Impact of Deforestation on Flooding**:
- **Sediment Runoff**: Without trees, there is increased sediment runoff during heavy rains. This leads to more water flowing into rivers and streams, increasing the likelihood of flooding.
- **Water Absorption**: Forests have a higher capacity to hold water compared to agricultural lands or grasslands. When forests are removed, the land cannot retain as much water, contributing to flooding.

5. **Conclusion**: Based on the analysis, the recurrence of floods in the plains of North India is primarily due to excessive deforestation.

6. **Final Answer**: Therefore, the correct answer is "deforestation".
