If there are the minerals present that create higher salinity in saltwater, but it is not a high concentration of them, that is when you get brackish water. The interaction of the two water masses of different salinities and densities in the estuary creates underwater turbulence and mixing that naturally flushes and energizes the coastal system. These areas are important in preventing downstream flooding and providing natural habitats to native species.
