What is the primary purpose of diversions in coastal Louisiana?

The primary purpose of diversions in coastal Louisiana is to build new lands and push back saltwater intrusion. This process involves redirecting river water, particularly from the Mississippi River, to the coastal wetlands. By doing this, the sediment carried by the river is deposited in areas that have been eroded or degraded, allowing for land rehabilitation and restoration of wetland habitats.

Moreover, these diversions help to counteract the effects of saltwater intrusion, which poses a significant threat to freshwater ecosystems and agricultural areas. The introduction of river water helps maintain a healthier balance of salinity in nearby estuaries and marshes, supporting diverse plant and animal life that is crucial for the overall health of coastal ecosystems. This is particularly important in Louisiana, where coastal erosion is a major environmental issue, and these efforts can contribute significantly to the sustainability of both wildlife and human communities in the area.
