Sediment gravity flows exhibit a large range of flow behaviours, making their dynamics hard to predict and the resulting deposits challenge interpret. Cohesive sediment containing clay are particularly complex, as behaviour is controlled by balance turbulent cohesive forces. A first set laboratory lock-exchange experiments investigated effect adding 25% very fine sand volume high-density with s...

In this study, a stand-alone sediment and contaminant model, SEDDEER (Sediment Deposition and Erosion), is presented. The model simulates one water box and underlying (multiple) sediment bed layers, and was developed for incorporation into water quality models. The processes incorporated in the model are: settling and deposition, resuspension, equilibrium adsorption/desorption, sediment-water i...

The Gyeokpori Formation in the Buan volcanic area primarily contains siliciclastic rocks interbedded with volcanoclastics. These sediments are characterized by a variety of soft-sediment deformation structures (SSDS). SSDS embedded poorly sorted conglomerates; slump folds also present formation. mechanisms and triggers causing not yet clear. In study, trigger was investigated using facies analy...
