When the water table is under the base of a footing at a depth equal ...
If the water table is located at the level of the base of footing below it, the surcharge term is not affected. However, the unit weight in the third term is modified.

When the water table is under the base of a footing at a depth equal ...
Explanation:
When the water table is under the base of a footing at a depth equal to the width of the footing, the bearing capacity of the soil remains the same. Let's understand why this is the case.
Bearing Capacity of Soil:
The bearing capacity of soil refers to its ability to support the load from a structure or a foundation. It is an important factor to consider during the design and construction of any structure.
Effect of Water Table on Bearing Capacity:
The water table is the level below the ground surface at which the soil is fully saturated with water. It plays a significant role in determining the bearing capacity of the soil.
When the water table is above the base of a footing, it exerts an upward pressure called the buoyant force on the footing. This additional force reduces the effective stress on the soil, which in turn reduces the bearing capacity.
However, when the water table is below the base of a footing at a depth equal to the width of the footing, the buoyant force is not exerted on the footing. As a result, the effective stress on the soil remains the same, and hence, the bearing capacity of the soil also remains the same.
This can be explained by the fact that the water table below the footing does not have a direct influence on the soil above it. The soil below the water table is already saturated with water, and the presence of the water table does not significantly affect the load-carrying capacity of the soil.
Therefore, the correct answer is option 'D' - the bearing capacity of the soil remains the same when the water table is under the base of a footing at a depth equal to the width of the footing.
