MODELLING 2DH COASTAL MORPHODYNAMICS INCLUDING THE SEDIMENT SUPPLY FROM RIVERS AND NATURAL STREAMS

The term “Watershed-Coast System” refers to the entities consisting of watersheds and the areas adjacent to their outlets, where the sediment supply from rivers and natural streams plays a key role in the evolution of coastal morphology (Samaras and Koutitas, 2014a). This work investigates the capabilities of a 2DH approach in modelling coastal morphodynamics under the strong influence of the sediment supply from rivers and natural streams. Applications are performed for a coastal area in North Greece using an integrated coastal engineering model developed by the authors. Results provide useful insights regarding the use of 2DH models in this work’s context and are deemed to contribute significantly to the study of Watershed-Coast Systems for management and engineering purposes (Samaras, 2023).
