(PhysOrg.com) -- When a river flows into the sea, the location is more than just a haven for water commerce. The mixing of fresh and salt water that occurs at an estuary also dissipates energy, as the different salinity waters combine into a state of less-ordered, uniform salinity. The mixing generates a significant 2.2 kJ of energy per liter of fresh water that flows into the sea.
