(7973) Estuary dam
Dam closing off the mouth of an estuary from the sea. This closure may take place for one or more of the following purposes : (a) creation of a reservoir for tidal power generation, (b) sweet water reservoir for irrigation, (c) prevention of salt water intrusion, (d) primary sea defence to replace long stretches of levees along the banks of estuary and lower course of the rivers. In most cases a sluice (regulator) is built in the estuary dam to allow discharge of river flow to the sea.
