Marine Brackish Water

Anusha Polampelli

Brackish water is water having additional salinity than fresh, however not the maximum amount as brine. it should result from combining brine with H2O along, as in estuaries, or it should occur in salt fossil aquifers. The word comes from the center Dutch root "brak". bound human activities will turn out salt water, applied science comes like dikes and the flooding of coastal fenland to supply saltwater pools for fresh prawn farming. salt water is additionally the first waste material of the salinity gradient power method. because of salt water is hostile to the expansion of most terrestrial plant species, while not acceptable management it is damaging to the setting (see article on shrimp farms). Technically, salt water contains between zero.5 and thirty grams of salt per liter—more usually expressed as zero.5 to thirty components per thousand (%), that could be a relative density of between one.0004 and 1.0226. Thus, salt covers a variety of salinity regimes and isn't thought-about a exactly outlined condition. it is characteristic of the many salt surface waters that their salinity will vary significantly over area or time.
