Analyse successivement, en prenant comme exemple la région de la plate-forme continentale britannique: le transport sédimentaire littoral et ses techniques d'observations| le transport dans la zone de déferlement, le transport sur la plate-forme
continentale (ou transport offshore), les relations du transport sédimentaire entre ces deux zones.
Consideration of the available equations for prediction of aeolian sand transport led to the development of a model which relies on optimization techniques for the production of improved performance. The model has been applied

Bedload transport measurements in two upland streams are considered as a function of the excess stream power exerted on the bed by the flow. An inverse depth dependence in the efficiency of the transport process was noted but although bedload
calibre increased as a function of discharge its influence on efficiency could not be demonstrated. However it was suspected that the size-sorting relationships of the bed-material in a number of rivers in relation to the transport efficiency might
in solute load transport has been underestimated. However, the low discharge period is important in the transport of dissolved material and this is in marked contrast to its very minor role in the transport of suspended sediment and bed load.

This paper discusses observations of burrowing activity over a one-year monitoring period at a site in coastal central California, presents models for quantifying the resulting sediment transport, and compares the results to both previous
Sublimation is important in the generation of loose sediment for wind transport in periglacial environments. This paper reports the results of a laboratory experiment which examines these thermophysical relations and presents an empirical model
