| Geological disasters on the superficial seafloor were revealed in geological investigation on the Yellow River subaqueous delta. Combined with dynamic triaxial tests and wave flume experiments, occurring conditions and forming patterns of liquefaction as well as motion of the liquefied soil were explained in this paper. Based on the viewpoint that the geological disasters were formed due to silty soil liquefaction under storm waves, re-stratification issue of the superficial stratum was analyzed. Movement of the liquefied soil agreed with the wave, leading to differentiation of the soil particles. Research issues in respect of geological, environment and engineering of storm-induced liquefaction were also discussed. |

| Early (post)larval fish constitute a significant part of the temporary hyperbenthos, i.e. of the fauna living in the lower reaches of the water column close to the substratum. Information on the densities and spatial and temporal variations of these stages, as well as on their lengths at the moment of occurrence, can be an important contribution to the knowledge of their dispersion, migrations and to the identification of possible bottlenecks in their recruitment. Therefore the hyperbenthos of the Voordelta, a shallow coastal zone in front of the Dutch Delta, as well as that of the subtidal channels and the intertidal brackish marsh creeks of the Westerschelde Estuary, was sampled monthly during one year by means of a sledge and a stow net. A total of 37... |

| L’interface terre-mer, prise au sens large, est un espace fragile, convoité et soumis à de multiples pressions sans qu'il n’y ait de vision d'ensemble des populations et des activités qui s'y développent, ni de maîtrise globale des multiples décisions concernant ce milieu. Or la montée du niveau de l'océan apparaît comme une des pressions majeures de ce siècle. Son ampleur et ses effets à long terme sont difficiles à identifier, et donc, à anticiper. Toutefois, si les causes sont encore incomplètement analysées et comprises, les premiers effets sont déjà observables sous diverses formes et sur de nombreux sites. Les impacts de cette élévation sont encore faibles aujourd'hui, mais les projections portent à penser que l’élévation du niveau de la mer va... |
