Hydraulic modelling and research

Since more than 40 years Svašek Hydraulics works on the development of hydrodynamic models. The main set of in-house developed hydrodynamic models is based on the Finite Element Method.
The main items of the total package are the hydrodynamic flow models FINEL2D, FINEL3D (resp. 2- and 3-dimensional) and the harbour resonance model HARES. Within FINEL2D, the MORFIN morphological modules are available to compute sediment transport and seabed development, both for sand and silt. MORFIN is also dynamically linked to the wave model SWAN.

Typical for the finite element method is that the model area is divided into a number of triangles, the so-called elements. The size and shape of these elements may vary within the model area, allowing flexible schematisations. Characteristic features of a specific region, like tidal channels and flats, the geometry of harbour moles and basins and the configuration of the shore line can easily be incorporated in the model. In the area of interest smaller element sizes can be applied. Hence, complicated nesting techniques are not required in this approach.

Being part of the same package the results of the various modules can easily be exchanged, e.g. changes in seabed level computed with MORFIN are directly linked to the hydrodynamic model.

Our models are continuously subject to research and development. If required, we will adjust the model to suit specific questions, instead of having to simplify the problem to fit it to an existing model.

Besides the in-house developed software, Svašek Hydraulics applies software packages developed by other parties, like SWAN, SWASH, WAQUA, XBEACH and SOBEK.
