Table II shows the data regarding the coastal erosion issue along the Selangor coastline. This data was obtained from the DID Selangor. From the table, it shows that coastal erosion is
divided into three categories. Based on the National Coastal Erosion Study commissioned by the Economic Planning Unit in 1985, category one can be regarded as critical erosion areas
where shore-based facilities and economic activities are in immediate and imminent danger. Moreover, the National Coastal Erosion Study 1985 indicate that erosion in category 2 as significant erosion areas where shore-based facilities andeconomic activities are expected to be endangered within 5 to 10 years if no remedial action is taken and lastly category 3 as
acceptable erosion areas that are generally undeveloped with consequent minor economic loss if coastal erosion continues
unabated.
