| Knowledge regarding the systemic vulnerability of coastal territories to erosion and flood has progressed during the last decades thanks to the consideration of hazards but also of other components such as the stakes, the management and the social representations of the coastal risks. However, in numerous cases the development and urbanization of coastal territories submitted to the coastal risks continues. It results in the increase of exposed populations as well as in the increase of the cost of exposed properties, increasing in return their vulnerability. So, in the objective to improve the management strategies and to strengthen the memory of the risk, the need to specify the characteristics of hazards remains important. In this sense, the intensity,... |

| Nearshore is an integrated part of the coastal zone, as well as beaches and coastal dunes. However, they remain poorly studied compared to the emerged part of the system, because of the limited access for scientific monitoring. The nearshore of Combrit - Ile-Tudy (south Brittany, France), addressed in this paper, is a good example. The first aim of this study is to present a methodology for the interpretation of old bathymetric surveys (supplied by the French naval hydrographic and oceanographic service SHOM) which considers all the inaccuracies related to this type of data. Then, this method is implemented in order to depict the morphological evolution of the nearshore by comparing the ancient bathymetric surveys (19th and 20th centuries) and the recent... |
