The Keteldelta concept envisions a nature-based delta system with dynamic islands that evolve over time through natural sedimentation and erosion processes. This MSc research will explore the morphological development of the proposed islands and surrounding channels, assessing how sediment transport and deposition shape the system over time.

Using existing hydrodynamic simulations (WAQUA) as a basis, the student will investigate how different sediment types (sand, clay) and supply strategies influence island formation, stability, and long-term evolution. The study will estimate the required sediment volumes, identify potential sediment sources, and explore the interactions between morphology, hydrodynamics, and ecology.
Depending on data availability and scope, the research may combine numerical modeling (e.g., Delft3D-MOR or XBeach), analytical approaches, and conceptual modelling. The outcome will provide insights into the feasibility and design principles for developing self-sustaining, morphologically resilient delta islands.
