This is an interesting report commissioned by the United States Army’s London office. It assumes 2 feet of ocean rise over the next 100 years, and while it mentions subsidence, it does change its calculations based on subsidence in Louisiana. Since coastal subsidence may be a meter or more over the next 100 years, this is a crucial omission. In general, its proposals might work for Holland, but do not seem well suited to geology of Louisiana and the threat of hurricanes.
