<P> Brackish water or briny water is water that has more salinity than fresh water , but not as much as seawater . It may result from mixing of seawater with fresh water , as in estuaries , or it may occur in brackish fossil aquifers . The word comes from the Middle Dutch root `` brak '' . Certain human activities can produce brackish water , in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming . Brackish water is also the primary waste product of the salinity gradient power process . Because brackish water is hostile to the growth of most terrestrial plant species , without appropriate management it is damaging to the environment ( see article on shrimp farms ) . </P>
