Abstract

Garlan, T.; Almar, R.; Gauduin, H.; Gosselin, M.; Morio, O., and Labarthe, C., 2020. 3D variability of sediment granulometry in two tropical environments: Nha Trang (Vietnam) and Saint-Louis (Sénégal). In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 495–499. Coconut Creek (Florida), ISSN 0749-0208.

The sediment variability of two tropical beaches was studied in order to provide the input data of the COASTVAR project's morphodynamic models. The longshore, cross-shore and vertical sediment organization of the first decimeters seems important to take into account in modeling. In particular, the presence of coarser underlying sediments, very frequently observed at all latitudes, may be at the origin of the slope of the beach. And these coarser sediments can also cause significant changes in sedimentary dynamics, when the most energetic events come to set them in motion. But the 3D characterization of beach sediments is not easy and the methods to achieve it are presented here.
