Construction projects may involve working with soil deposits that are under a body of water or below the groundwater table that exists at a land area. (a) For soil submerged below water, explain what is meant by the term effective unit weight. (b) What is the importance of knowing, or being able to determine, an effective unit weight for a submerged soil?
