The 200-mile economic exclusion zone encompasses an area of about 4.47 million square kilometers. One of the earli- est extensive beach nourishment projects undertaken in the United States was in Harrison County, Mississippi, in the 1950s. Chapter 5 Coastal Area Planning and Management Wulder, M. A. et al. 22, 615632 (2009). The Eastern Pacific is particularly vulnerable to widespread erosion, most notably during the large 1997/1998 El Nio event. Dune protection is extremely important for the health of the coastal ecosystems, as well as for property protection. (1996) set down specific items for evaluation in each of the three objectives, and proposed an integrated evaluation method for judging management schemes relative to them. The southern oscillation.
