#Software

The GeoModeller software is used to define the 3D geological architecture (lithologies and faults) of an area, using data of different types and formats (maps, cross-sections, boreholes, geophysical surveys, hydrogeological data, etc.), which can be modified at any time.

XLKarst rapidly implements various methods classically used in karst hydrology for the hydrodynamic characterisation of karst systems.

EFISPEC3D is mainly used to simulate wave propagation in complex geological environments, especially for earthquake applications. The software can also be used more generally to solve problems governed by the equation of motion in three dimensions.

USIM PAC is a process modelling and simulation software for the design, the monitoring, and the optimization of industrial processes.

ECHANT is a calculation software used in the design of sampling protocols and campaigns. It allows to calculate the fundamental sampling error.

BILCO is a software for data reconciliation by mass balance. It allows to obtain an instantaneous image of a process and to quickly provide solutions for material flow management problems.

MISP is an analytical model that calculates the impact on groundwater of a pollution source above the water table.

When confronted with epistemic uncertainty, “conventional” probability theory tools frequently appear too restrictive. Other, more flexible representation tools can then be put forward. The HYRISK package propagates and uses random and epistemic uncertainties together.

Zappel is a tool that plots the catchment area and the position of the isochrones of a borehole under the effect of pumping.

The HYPST-R tool was developed in support of a study aiming to provide information for groundwater resource managers about the uncertainties relating to estimators of the chemical condition of the groundwater bodies they calculate.

The HYPE tool allows the statistical study of chronicles of evolution of groundwater quality. HYPE draws on several years of studies on the applicability of statistical methods to the study of groundwater quality and tests on theoretical and real data. It thus integrates the most powerful and robust statistical methods in this specific field.

Developed by BRGM, the ÉROS software is used for hydrological modelling of rainfall,river flow rate and groundwater table levels of a heterogeneous catchment area divided into sub-basins.
