CATHERINE, developed by the BRGM, analyses simultaneous variations in the levels of a river and an adjacent aquifer.

Conexmin is a tool which calculates the ratio of the volume abstracted from a river to the volume taken from the pumping well, based on the characteristics of the alluvial aquifer, the distance from the well to the river and the pumping time.

DEPJAU (for Dépouillement des jaugeages meaning "gauge measurements analysis") uses river gauge data to calculate the flow rate deduced from flow velocity measurements made in different profiles on a transect.

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.

ESPERE is designed for rapid simultaneous calculations using up to ten different methods for estimating aquifer recharge or effective rainfall.

GARDENIA is an application developed by the BRGM for lumped hydrological modelling of a catchment basin via the rainfall/river flow/groundwater level budget.

The GDM Suite has been developed by the BRGM to manage, display and model geological data, in various fields: geology, town and country planning, water resources, pollutions, natural hazards, mineral resources, geotechnique, geothermal energy...

GesFor is a BRGM software package for drilling professionals and is supplied free of charge.

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.

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.

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.

MARTHE has been developed by the BRGM for 3D modelling of flows and mass and energy transfers in hydro-systems. Modelling includes aquifers, rivers and vadose zones.
