<span>During
the flow of the river, water force gets remains alongside the riverbanks. As
the water hits a larger body of water, the force in its flow became slow and
the sediments it picks up settled on the lowest point of the riverbed. During
the time Mississippi River and the Gulf of Mexico hits each other, sediments
are deposited and it created the South Louisiana land. In order to use this process
to rebuilt wetlands, dredged material from the Mississippi River must be used
to create alteration pipelines of sediments. This process replicates the building
process of original land and sediments deposition. </span>
