Custom seismic alerts
Are you an infrastructure or civil engineering works manager or a transmission network operator; are you wondering about seismic risk prevention on your site or nearby in the event of an earthquake? BRGM offers you its earthquake alert transmission and personalised management service to meet your needs for the prevention, safety and continuity of activities at your facilities and structures.
The MétéEAU Nappes website is an innovative platform that supports decision-making for groundwater management. It enables users to monitor groundwater levels in real time and to establish forecasts of future levels.
MétéEAU Nappes, a tool for the real-time monitoring and forecasting of groundwater levels
Are you a public authority or organisation involved in managing water resources? Would you like to know the current state of the water table levels in your region and be able to establish reliable forecasts? BRGM's MétéEAU Nappes tool enables you to consult the status of your water resources and facilities in real time and thus to put in place an effective water-resource management and protection plan.

HYRISK: software for handling random and epistemic uncertainties
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: plotting the isochrones and catchment area of a water well
Zappel is a tool that plots the catchment area and the position of the isochrones of a borehole under the effect of pumping.
HYPST-R: simulation of uncertainties to assess the chemical condition of groundwater bodies
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.
HYPE: a tool for characterising and evaluating trends in the temporal evolution of groundwater quality
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.
ÉROS: a semi-global hydrological modelling application for a catchment area divided into sub-basins
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.
DEPJAU: River gauge analysis and flow rate calculation
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.
Conexmin: calculation of the influence of alluvial aquifer pumping on the flow-rate of a watercourse
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.
