Abstract
    The general research strategy for the development of an innovative numerical sediment transport model applicable as engineering tool for coastal and estuarine morphodynamics is presented . It consists of two major steps: (1) the creation of a high-resolution hybrid model based on two-phase flow theory, where the model can easily be reduced to a computationally less expensive mixture theory model in the dilute part of the domain; (2) a scale analysis and the development of a strategy to upscale the high-resolution strategy to a coarse scale model applicable to large-scale 3D engineering problems.
