| Abstract |
First, results from Telemac3D hydrodynamic simulations for the case of a seaward coastal defense line spanning along the entire Belgian coast, are presented. To this end, two three-dimensional unstructured Telemac models are utilized, namely the Zeebrugge (ZB) model, and the Scaldis model, for comparison of the numerical results. In addition, the perspectives of a new finite element mesh generator, named GMSH, are investigated through a successful testing in the construction of a qualitative grid for one of the investigated scenarios. Next, the sea level rise effect on the hydrodynamic flow at the Belgian coast and especially on the Zeebrugge port accessibility is investigated again by means of the Zeebrugge Telemac3D model. Three different scenarios of future sea level rise are considered, i.e. a moderate sea level rise of 60 cm by the year 2100, a warm scenario with sea level rise of 90 cm and a worst case scenario of sea level rise scenario of 200 cm. The main conclusion is that the impact of sea level rise on the port accessibility is limited. Only in the worst case scenario a significant impact on the LNG carriers access (with respect to the maximum allowed cross currents 1.5 kn) is observed. |
