Brackish water

HelpCenter Definition
Brackish water is water that is saltier than fresh water, but not as salty as seawater. It may result from mixing of seawater with fresh water, as in estuaries, but also certain human activities can produce brackish water, in particular certain civil engineering projects such as dikes and the flooding of coastal marshland. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment. Source:
