Where would the water go: Coastal Landscape Evolution and Prediction

My current research focuses on the end of terrestrial systems and the beginning of aquatic ones. This addresses the question of “where the oceanic forces extend to and how would that change through time?”. The unique hydro-eco-geomorphic interactions promote a both reactive and self-evolving landscape. A fully coupled 3D hydrodynamic model was developed and adapted to a complex coastal landscape including vegetation. Equilibrium Land/Water coverage was investigated under a variety of possible environmental factors. Furthermore, mechanisms of Land/Water partition are revealed among the intertwined hydro-eco-geomorphic feedbacks.
