Modelling the effect of water depth on rock cutting processes with the use of discrete element method

Efficient rock cutting is still a challenge in the dredging industry. A new method that takes into account the effect of water depth could refine rock cutting processes.

Process-based Modelling of Mega-Scale Equilibrium Conditions in the Dutch Wadden Sea

As a result of the closure of the Zuider Sea 75 years ago, as well as subsequent interventions and natural disturbances, the Wadden Sea is no longer in an equilibrium or stable condition, but modelling indicates that in the long-term a new dynamic equilibrium state should return.

Modelling the Sedimentation Process in a Trailing Suction Hopper Dredger

For production, sand quality and environmental reasons predicting the amount of the so-called overflow losses when using a trailing suction hopper dredger is very important.
