Mitigating suspended-sediment environmental pressure in subsea engineering through colliding turbidity currents

Turbidity currents have extensively been explored in quiescent environments. However, during several underwater activities (e.g., dredging and deep sea mining), generated turbidity currents could travel in opposite directions and interact with each other, which could largely influence their hydrodynamics and sediment transport capacity....

Erosion of sand at high flow velocities: An experimental study

The safety level of a dike is expressed in terms of risk. Risk is defined as the product of the probability of inundation of a polder (after failure of a dike) and the expected damage (casualties, economic damage and damage to the infrastructure) caused by inundation. The rate of inundation determines the amount of casualties and depends heavily...

Predicting the breaching production of a slope during a wet mining process

An underwater slope can collapse by liquefaction, wedge failure or breaching. Breaching is the most unknown process and has a low predictability. Dredge mining is strongly influenced by the breaching process. If breaching can be accurately predicted, the efficiency of the dredging production can be maximised.It is the objective to know what...
