Digital simulation consists of using specialized software to understand and analyze the behavior of groundwater. The various operating software, like Feflow and Modflow, use the principle of conservation of mass. Feflow is particularly effective because it uses the principle of finite elements and is therefore more flexible when the topography is highly variable on a site.
A numerical model can be compared to a sketch but displayed on a computer. The validity of the model, commonly known as the timing allows to know the effectiveness of the model compared to reality. It’s primarily comes to compare some results observed in the field with those simulated.
Once the model built, it is possible to perform an infinite number of simulations, such as the estimate of the alimentation and protection areas of a catchment well or transport of a contaminant in the future. A numerical model is an important tool, even necessary for municipalities that feed into groundwater. This allows to respond quickly and precisely to several questions of the managers.
Hydro-Ressources uses software on the cutting edge of technology, as the latest version of Feflow (7) using an unstructured mesh. We use the Leapfrog software to build the faults geometry and lithological units.
