Méthodologie pour une simulation des transformations granulométriques de sables de la zone d'avant-côte ArchiMer
Barusseau, Jp; Diouf, Mb; De La Bardonnie, M; El Ghandour, N.
The grain-size of mature coastal sands changes rapidly in response to the variation of the energy regime which provokes either erosion or deposition of fractions of the textural assemblage. Whatever the dynamic conditions, questions of paramount importance such as the size of grain populations transported simultaneously, the most common size of the grains in movement and the grain-size range of the sediment fraction involved ape still poorly understood. The present paper deals with an attempt to describe this fraction without any consideration of the processes responsible for the observed changes. A major problem results from the fact that the distribution of the mobilized fraction cannot be known and described by direct comparison between the initial and...
