Effect of Coarse Particle Volume Fraction on the Yield Stress of Muddy Sediments from Marennes Oleron Bay
Provedor de dados: 5
Autores: Pantet, A.; Robert, Serge; Jarny, S.; Kervella, Stephane.
Coastal erosion results from a combination of various factors, both natural and humaninduced, which have different time and space patterns. In addition, uncertainties still remain about the interactions of the forcing agents, as well as on the significance of non-local causes of erosion. We focused about the surface sediments in the Marennes Oleron bay, after a general description of the site that has many various activities. The superficial sediments show a mechanical behavior, mainly depends on the fine fraction for a composition that contains up to 60% of sandy material. Fine sediments fraction has a typical yield stress depending naturally of concentration or water content. This yield could be modified slightly or significantly by adding silt or sand....
