Coastal erosion and accretion
| Definition : | Percentage of the coastline that is accreting, eroding and stable. |
| Description : | Coastal erosion is measured as the gradual loss of sediment and a coastline is described as 'eroding' when this loss of sediment exceeds a certain critical standard or baseline. Methodologies and standards for establishing whether a coastline is accreting, eroding or stable are not uniform among coastal states. The part of the beach profile that is considered for erosion studies also differs from country to country. Monitoring the evolution of accretion and erosion, sea level and the effects of extreme weather is of crucial importance for developing propoer local risk assessment and adequate policies in shoreline management. |
