FINEL (FINite ELements) is a hydrodynamic flow model which can operate in 1D, 2DH, 2DV and 3D mode. FINEL has morphological modules to compute sediment transport and morphological seabed development, both for sand and silt. FINEL is (online) coupled to SWAN to take the interaction between waves, currents, water levels and varying bed levels into account. FINEL is based on the finite element approach and applies a flexible mesh with triangles. This offers almost unlimited flexibility in grid generation. Special features, like harbour moles, or a complicated coastline can be accurately incorporated in the grid. FINEL is highly parallelised for efficient fast calculations on our in-house computational HPC cluster.
FINEL can deal with ocean, tidal, river, wind driven, wave driven and salinity driven flows as well as cool water discharges and sediment plume dispersion for environmental impact assessment. FINEL has dedicated sand, silt and coupled sand-silt interaction modules to handle morphology. Several state of the art sediment transport formula are available. FINEL can simulate morphological development accurately for periods up to 100 year!
For more than 30 years now FINEL has been applied successfully for coastal, harbour and river engineering projects all over the globe.

Svašek Hydraulics has developed several large scale FINEL models, i.e. European Continental Shelf (ECSM), East Coast North America (AECM) and South East Asia (SEAM). This models can be used for a whole range of engineering purposes. For example of water level and current forecasts for ship routing, off-shore construction activities or extreme sea level analysis.
