- Abstract
- SLIM, the Second-generation Louvain-la-Neuve Ice-ocean Model, based on the discontinuous Galerkin finite element method to solve one-, two- or three-dimensional continuity, momentum and reactive transport equations on unstructured meshes. The main focus of SLIM is to simulate geophysical and environmental flows in multiscale domains, especially land-sea continuum. Because of its flexibility, this simulation tool has been applied to a wide range of complex geophysical and environmental flows. It is worth using SLIM to study on new river-sea continua such as Mahakam, Mekong and Yangtze to model hydrodynamics and suspended sediment transport. SLIM is used in Mahakam to model and diagnose transport processes in the Mahakam delta using a 3D model based on advanced diagnostic methods inspired by CART (www.climate.be/cart) and pertain to both water and sediment. A coupled 1D – 2D model will be applied in the Mekong River Basin, where 1D model is used for computing hydrodynamics in the upper part, from the boundary of China and Laos to Kratie, Cambodia; 2D model is developed for the domain of interest, Tonle Sap lake, the Mekong delta and estuary, that requires accurate representation of the topography, complex coastlines and channels. The hydrodynamic environment and sediment transport in the Yangtze River Estuary and its adjacent sea area will be simulated based on SLIM 2D model, mainly focusing on the seasonal variations of the estuarine turbidity maximum in the YRE and analyzing the reasons of these variations.
