As rivers flow the force of the water picks up sediment along the banks. When the force of the flow of water is slowed down by the river hitting a larger body of water, this sediment settles at the bottom of the riverbed. Sediments deposited when the Mississippi River hits the Gulf of Mexico formed the land in south Louisiana. To use this process to rebuilt Louisiana vanishing coastline material dredged from the Mississippi river and other navigation channels Could be used to create marsh and rebuild wetlands through construction in sediment diversion pipelines. This human designed process imitates to the original land and building process deposition of sediment. HOPEFULLY it helps
