Answer to Question 1
ANSWER: Beachfront sand dunes absorb the energy of waves and advancing storm surges and can reduce damages to coastal communities. Cypress forests or thickets of mangroves limit the shoreward advance of waves and dramatically slow a surge's landward advance. Unfortunately, many of these areas have been modified or damaged over the years through development. Some communities have now recognized the importance of these areas and are working to protect or restore them. Human alterations of dunes and mangrove stands that would increase potential flood damage are prohibited. Even walking on dunes is generally prohibited because it disturbs the sand and any vegetation covering it, thereby making the dune more susceptible to erosion by both wind and waves. To protect the dunes, people build elevated walkways over dunes to beaches.
