This thesis presents the development a generic morphological model for both structured and unstructured grid and the extension to a biogeomorphological model.

For the morphological model, numerical algorithms are adjusted to adapt unstructured grid and are validated against analytical solutions and flume experiments. For the bio-geomorphological extension, relevant ecological processes are coupled with morphodynamic processes at various scales and are validated against the field data in Lake Veluwe. Capability of the model has been explored for applications of two salt marsh restoration cases in United States and the large scale morphodynamics of shoreface connected radial sand ridges located in South-east China Sea.

Validations and applications show that this modelling platform is capable to be a multidiscipline research tool for morphologists and ecologists / biologists.
