It has been a fascinating experience. The cruise ship made it vacation-like, due to the integration of amenities that enabled passengers to enjoy the ride, throughout the scheduled weeks. However, coastal erosion has become a major concern because it raises a negative sense of security.
The rising sea levels erodes the beach, it is an onshore process. Leatherman et al. (2000) explain that strong waves crashing on to the shoreline destabilize the coastal area, which might result in coastal subsidence. When the waves. Downstream erosion of accumulative forms is an offshore process. It accumulates the coastal sand and deposits offshore, thus starving the coastline, making it vulnerable to other erosional factors (Leatherman et al., 2000). It results in the formation of features such as the sand spit among others. The anthropogenic features that cause coastal erosion include port development, as well as construction of seawalls. They compromise the stability of the area, and promote development of rip currents. This is an erosional mechanism along the beach.

Beach replenishment has become a popular remedy of coastal erosion in the United States of America. The process involves pumping sand on to the eroded beach. Over 59% of the beaches in Florida are experiencing the same problem. This is a result of construction, as well as maintenance of navigation inlets, which are more than 60 in the state. Dixon, Katharine & Orrin (1991) approximate the total cost to be $14million. The cost does not worth it because the introduced sand will be washed away by the rising sea levels. Also, sudden addition of massive sand can kill the animals that live along the beach. The material used is subject to depletion. It is mind from areas which will get exhausted in future. So it is ineffective in decreasing beach erosion (Philip, Michael & Jones, 2006).
