COASTAL EROSION
2.4. Human Enhancement of Coastal Erosion
Hurricanes, stormsurges and tsunami contribute the unknown but probably major catastrophic part of the coastal erosion process, superposed on the average daily wave attacks. The process of erosion is, however, considerably enhanced by such human activitie
s as mining of sand, damming of rivers
(thus cutting off the supply of terrigenous materials to the beach
compartments) and destruction of such natural barriers as coral reefs and
mangroves.
To see the effect of wave-erosion on a seawall which was not built with adequate 'wings':
The ratings in our questionnaire were relatively high, with a mean of 2.84 on a scale of 5 (most serious). The highest consistent rating was for Nevis (4, i.e., 100%).
