Abstract:
It is important to quantify erosion rates so that it could contribute to effective management of coastal areas. This requires the use of Geographic information Systems in order to perform spatial and geostatistical analysis. It is a useful tool that can be used in identifying coastal vulnerability and generation of maps of coastal risk. This study compares rocky shores of Caution Reef and sandy shores of Wlotzkasbaken along the Namibian coast. Erosion rate of 1.13m/yr with a seaward displacement of 0.72m was observed at Caution Reef indicating its stability overtime. Wlotzkasbaken showed an erosion rate of 16.29m/yr with a shoreline erosion distance of -40.23m overtime. Good knowledge and prediction of rates is an important aspect to consider due to the challenges faced by most coastal states as a result of coastal erosion
