Document Summary
In the us there are sediment-starved, eroding beaches all the way down the east coast. To move the sand requires energy during a hurricane beaches suck up some of the energy. Coral reefs also absorb some energy during storms and are protective for coastlines. We want to be able to control stream flows to prevent flooding. Use dams as a flood control method. Sediment has to be removed for dam hydroelectricity function. Sand must be removed upstream of dam otherwise water will flow over. Beaches at the ends of streams become sand starved. Low-lying areas worldwide are vulnerable to sea level rise. Study showed that south-east asia is vulnerable to sea level rise. Estimated that 100 000 000 people will be in harm"s way in 2100 since sea level will be much higher. Ex) maldives average elevation in maldives is 1. 5 m above sea level. Exacerbates the destructiveness of storms and cyclones on coastal areas.
