As the water recedes, the sediments rise and fill the depression again. This causes the ground to rise and form a thick layer of soil. The banks form levees made of sediment silt and other materials pushed aside by the flowing. The river here is tidal and when the sea retreats the volume of the water in the estuary is reduced. Cells that contain two sets of chromosomes are said to be diploid . Levees and floodwalls are typically built parallel to a waterway most often a river to reduce the risk of flooding on the landward side.
