Question

According to Ministry of Water Resources, the waterlogged areas are the land areas having

• A. Water-table within 2 m from land surface
• B. Water-table between 2-3 m from land surface
• C. Water-table below 3 m from land surface
• D. Standing water column

Hint:

Waterlogging:
- Water table within 2 m of the surface.
- Affects root respiration and crop growth.
- Requires drainage for reclamation.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This question tests knowledge of the definition of waterlogged areas.

Step 2: Detailed Explanation:
According to the Ministry of Water Resources, waterlogged areas are those where the water-table is within 2 m from the land surface (A).
When the water table is within 2 m, the root zone becomes saturated, affecting plant growth.
Other criteria:
- Water-table between 2-3 m (B): Not considered waterlogged.
- Water-table below 3 m (C): Not waterlogged.
- Standing water column (D): This is a different condition (ponding).
Thus, waterlogged areas have a water table within 2 m of the surface.

Step 3: Final Answer:
Thus, waterlogged areas have a water-table within 2 m from the land surface, which corresponds to option (A).
