On the status and mechanisms of coastal erosion in Marawila Beach, Sri Lanka

Research overview Coastal erosion has been a serious threat to the properties and livelihoods of coastal communities on the western coast of Sri Lanka. Since the cause of the erosion was not fully investigated, there were arguments over the selection of countermeasures among beach users.
