Coupling the hydrodynamic models and/or wave models with a sediment transport model allows for simulating the transport of sediments and bottom evolution. At sheltered sites and during slack water, the sediment settles back to the bed. The sediment is brought into suspension and transported by the water forced by currents and waves. The turbidity and morphology of the Belgian coast and Scheldt estuary is strongly influenced by fresh water discharges, seasonal effects, storms, climate change, but also by human interventions like channel deepening and maintenance, infrastructural works and coastal defence. One of the major concerns of waterway-, estuarine- and coastal managers is the changing bathymetry and turbidity introduced by natural or anthropogenic changes in fine sediment and sand transport. Sediment transport and morphological models SWAN, Mike21BW and SWASH are mainly used for wave transformation, DualSPHysics for wave-structure interaction (see also CFD section below) and XBeach for coastal morphological studies. Flanders Hydraulics Research mainly uses SWAN, Mike21BW, SWASH, DualSPHysics and XBeach. Numerical modelling of waves is a way to study the behaviour of coastal defences. We utilise them, for example, in scenario analyses of changing climatic conditions or changing water demand. We rely on water balance models (such as MIKE Basin) for studies on water availability and water allocation. The 2D version performs computations more quickly and provides operational predictions. The 3D version is mainly used for salinity and sediment (sand and silt) transport calculations. The model is maintained by Flanders Hydraulics Research in 3D and 2D versions. By creating and maintaining the NEVLA schematisation in this software, the model can easily be used in an international (Flemish-Dutch) context. SIMONA stands for РІР‚ВSImulatie MOdellen voor de NAtte waterstaatРІР‚в„ў and the instruments which the Dutch government (Rijkswaterstaat) uses for its water management tasks. All these rivers are included in the model up to their tidal boundary. It encompasses the Belgian coastal zone, the Western Scheldt, the Sea Scheldt and the Durme, Rupel, Nete, Dijle and Zenne tributaries. The NEVLA model, short for РІР‚ВNEderlands-VLAamsРІР‚в„ў, is a hydrodynamic model developed in the SIMONA software. This allows us to make forecasts at least 4 times per day for the next 48 hours for all navigable waterways in Flanders. This database continuously stores information on rainfall, discharges, water levels and sediment quantities based on field measurements.

In addition to water movement, these software packages also contain morphology modules.Р”Р‡or the operational forecast models, Flanders Hydraulics Research connects its hydrological and hydrodynamic models to the WISKI database via web services. Typical study topics are scenario analyses to support water management, planning and policy development. We use hydrodynamic models in both studies, advice and research as well as for our operational forecast models.

We work on new developments for several of these software packages by writing new code for specific applications or modules, or by extensively testing new functionalities. These software packages also include modules to simulate sediment transport.Р”Вepending on the functionalities required for the job and the partners, we apply programmes such as TELEMAC, Delft3D and MIKE21. Flanders Hydraulics Research uses these models for the coastal zone, the river deltas and for specific issues such as saltwater intrusion in ports. In terms of 2D and 3D hydrodynamic models, a range of applications is possible.

We use models such as MIKE11 which we maintain and update to reflect the actual situation as closely as possible. Hydrodynamic modelsР”Р‡landers Hydraulics Research mainly uses 1D hydrodynamic models to calculate water levels and discharges in rivers and their floodplains as a function of time. WetSpa) and highly detailed, physics-based and fully distributed models (e.g. For research assignments, we make comparisons between conceptual models (NAM, PDM, etc.), mixed conceptual physics-based models (e.g. Most hydrological models, especially operational models, from Flanders Hydraulics Research are conceptual reservoir models. We use these to define the boundary conditions to be used in hydraulic models and water balance models. Sediment transport and morphological modelsР”Р‡landers Hydraulics Research uses hydrological models to calculate the runoff from a river basin to the waterway. We are familiar with numerous software packages for a wide variety of applications. We continuously maintain and extend the portfolio. Flanders Hydraulics Research has the proper in-house expertise to select the most appropriate tool from the existing portfolio of models for every application. We use a variety of commercial software, open source solutions and proprietary programmes and tools for our numerical modelling.
