Coastal morphology Introduction Climate change has been quite a controversial topic. Quite a number of studies and researches have been done in the recent past and are still being done aimed at looking at its impacts of climate in the various parts of the world.
The unite kingdom is has experienced varied effects off climate changes as well as changes in the sea level. It is form the effects that we can make predictions as to the potential changes on the UK coastal waters. Rising sea levels threaten to overwhelm the low-lying areas, enhance intrusion of salt water in coastal aquifers and intensify the coastal erosion. By 2060, National Rivers Authority (NRA) estimate that the average sea levels in Wales and other coastal areas will have increased by more than 30 cm. As much as 30 cm may not seem much the Department of Environment (DoE) notes that a slight rise in the average sea level would heighten the frequency of intense levels of water resulting from storm surges. The likely impact of increased sea levels blended with higher storm surges was illustrated best in Towyn in 1990 when surge of 1.3 m height flooded ten square miles and resulted in damage worth about 31 million pounds. Extreme events such as these are only likely under changed climatic conditions (Buckley 2010, p.375). However, there are uncertainties as to the likely increase since there is no knowledge as to the contribution that should be expected from the three key processes that result in a rise in sea level. ...
