WAQUA is a water movement and water quality simulation system, able to perform two- and three-dimensional computations. It is used for hydrodynamic and water quality simulation of well mixed estuaries, coastal seas and rivers.



WAQUA is a water movement and water quality simulation system, able to perform two-dimensional computations. It is used for hydrodynamic and water quality simulation of well mixed estuaries, coastal areas and rivers. The WAQUA software is based on SIMONA, a flexible concept for the development of modelling software (finite difference method). The 2-dimensional hydrodynamical model WAQUA computes water levels, currents and particle transport in open water.

WAQUA considers a study area that can be characterised by curviform shaped, quadrangular grid of computation points. Grid sizes vary from small (1 m) to large (16 km). The corresponding grid cells are attributed with linked information such as bathymetry and bed roughness.

Svašek Hydraulics has developed several WAQUA models for the Dutch coast, estuaries and rivers by order of Rijkswaterstaat. Besides developing, Svašek Hydraulics has a large expertise on using WAQUA models in a decision-making process.

With the use of specific in-house developed presentation techniques the WAQUA results can be presented in a visually clear manner.

In SIMONA a part called TRIWAQ is able to perform three-dimensional computations.
