The study looked at how freshwater from canals affects the Indian River Lagoon in Florida. By analyzing different factors like water flow and weather, researchers found that the freshwater discharge has a big impact on the lagoon's movement and mixing. The pressure from the river plume pushes water towards the front where it meets the lagoon. A difference in density between the lagoon and the discharge point causes a flow of denser water below the surface. The amount and timing of freshwater discharge affect how salty the water is. Wind also plays a role in shaping the direction and size of the river plume.
