In case of non-cohesive soils such as sand and gravel ___________ reduction in allowable bearing capacity of the soil should be applied, if the water table is situated below or near the bearing surface of the soil. Correct Answer 50%

However, if water table is situated below the bearing surface of the soil at a depth equal to the width of the foundation trench, no such reduction should be applied. But in this case, 50% reduction is applied. For intermediate depths of the water table, the proportion and percentage reduction should be applied.
