What is the primary aim of freshwater diversion in coastal management?

Freshwater diversion in coastal management is primarily aimed at managing salinity levels within estuarine environments. By introducing freshwater into areas that may be experiencing saltwater intrusion, this practice helps to lower salinity. High salinity levels can be detrimental to freshwater ecosystems and the species that inhabit these areas, as many aquatic organisms have specific salinity tolerances. By reducing salinity, freshwater diversion can create a more favorable environment for various plant and animal species, thus promoting the health of the ecosystem.

While improving aquatic habitat and enhancing soil quality are important aspects of coastal management, the direct objective of freshwater diversion is specifically focused on the control of salinity. This is crucial for protecting habitats that are vital to fish and wildlife, as well as for supporting the overall ecological balance within the coastal ecosystem.
