Bay Mud Settlement
I am not a geotechnical engineer, but I have a question concerning the settlement of bay bud with several feet of fill on top, and a high water table. I understand the logic concerning the long term settlement of the bay mud due to the weight of the fill, but my question is in regards to the effects of lowering of the water table in the fill. It has been described to me that by lowering the water table, the fill is now no longer bouyant and therefore heavier. This heavier weight then results in additional settlement of the fill. This does not make since to me, as the total weight on top of the bay mud is heavier with fill and water than with just fill. Am I missing something?
In addition, what happens when the water table is lowered into the bay mud?
