Description:"Erosion on the 42-kilometer manmade beach between Biloxi and Pass Christian takes three forms. The southeast and southerly winds that prevail for much of the year blow sand over the seawall onto the highway bordering the beach to the north. Storm water from rain washes sand down the beach toward the Mississippi Sound to the south. Wave action and currents remove sand from the beach-water interface during high-energy events. Current beach management practices exacerbate the erosion process and shorten the time interval between renourishment projects. Raking and grooming the beach fluffs the sand, increasing its vulnerability to erosion caused by wind and storm water runoff. Heavy equipment compacts the sand beneath the fluffed layer. The ability of rainwater to infiltrate the compacted sub-sand is reduced, resulting in more water transport down-beach than would otherwise be the case, increasing sand transport with the runoff. Use of native plant species on the beach represents an alternative to current management practices for much of the beach. Native plants are adapted to survive in the harsh conditions that are common in a beach environment. Native plantings will inhibit or halt all three erosion processes, allowing renourishment projects to be delayed or avoided"--National Sea Grant Library publication website.
