摘要

Method of constructing a dam at the mouth of a river in a reclaimed from the sea, in order to capture and store for later use, water flow to the river pours daily to the sea.; The present invention aims at constructing a reservoir into the sea at the mouth of a river, so as to allow capture and store water discharged into the sea, for which it is isolated completely by levees, an immediate coastal sea area, comprising the mouth of the river, forming an enclosure which delimits the reservoir and encloses the water pouring river. Subsequently, using the pumping sea water that has been trapped (that being denser, preferably occupy the bottom of the reservoir) is ejected, to check that it is fresh water only. This invention provides means to capture at least the minimum ecological flow of the river, so that if implemented, will contribute effectively to solving the problem of drought suffering from large areas of our country.
