"The aim of the project is to develop, validate and demonstrate a numerical tool for the modelling and simulation of dredging applications. It is aimed to solve the numerical issues associated with large deformations and fluid pressures that occur in the interaction between soils and fluids. This effort will result in a joint computer code that combines earlier pioneering work of the participants (Cambridge and Deltares) in the field of soil-fluid interaction.During the project new methodologies will be developed, the advanced code will be intensively validated using benchmark problems and will demonstrated for dredging applications. The main focus will be on the modelling of soil-fluid interaction problems related to the following three dredging applications: 1) dropping of geocontainers with interaction between pore water and open water, 2) liquefaction and marine slope slides including the dredging of soils and 3) erosion and scour around offshore and near-shore structures.A major impact of the new software and of the joint effort of the participants through a collaboration in the proposed project is expected as expressed by the dredging industry supporting the proposed project (i.e. Van Oord Dredging and Marine Contractors, Royal Boskalis Westminster, Dredging International and Jan de Nul)."
