2016-12-19  Inter-bank erosion is an integral part of the mud-bank migration process. The extent to which the shore- welded part of a mud bank is preserved from erosion in the inter-bank area in the course of the bank migration process determines the degree of coastal progradation generated by each bank.get price

Combined with global climate change, increased sea-levels and sea-storms, the consequences in terms of coastal erosion could be severe. The total sand yield for the 18 eThekwini rivers was found to be between 480,000 to 720,000 m. 3. per year.get price

Coastal Erosion an overview ScienceDirect Topics

However, the urbanization of coastlines involving activities such as offshore dredging, decreasing sediment supply from rivers, and the destruction of seagrass meadows, marshes, and coastal sand dunes can intervene in coastal processes and exacerbate erosion (Airoldi et al., 2005). Preventing the recession and destruction of these economically, socially, and politically important coastal areas has get price
