What is the primary purpose of sediment diversions in Coastal Louisiana?

The primary purpose of sediment diversions in Coastal Louisiana is to restore and rebuild wetlands using sediment. These diversions are engineered systems that redirect sediment-laden river water into adjacent coastal areas that have experienced land loss. This process not only replenishes the soil but also promotes the establishment of new wetlands, which are vital for ecological health, providing habitat for wildlife, and serving as natural buffers against storm surges and coastal erosion.

By allowing the flow of sediment-rich water into areas where marshland has degraded, sediment diversions help to counteract the effects of subsidence and erosion, thus contributing significantly to the sustainability of Louisiana's coastal environments. This restoration is crucial for maintaining the unique ecosystems of coastal marshes, which support diverse flora and fauna and provide protective benefits for nearby regions.
