The enhancement of seawalls near marine environments can bring about increased shadowing results in the waters bordering the seawall. Shadowing minimizes the light and visibility within the water, which may interfere with the circulation as well as foraging capacities of particular species. The debris surrounding seawalls often tends to have less desirable physical residential properties (Greater calcification levels, less structural organization of crystalline framework, reduced silicon material, and less macroscale roughness) when compared to natural shorelines, which can provide issues for species that reside on the seafloor.
