Bank erosion of navigation canals in the western and central Gulf of Mexico
Cindy A. Thatcher, Stephen B. Hartley, Scott A. Wilson
2011, Open-File Report 2010-1017
Erosion of navigation canal banks is a direct cause of land loss, but there has been little quantitative analysis to determine why certain major canals exhibit faster widening rates (indicative of erosion) than others in the coastal zones of Texas, Louisiana, Mississippi, and Alabama. We hypothesize that navigation canals exhibit...
