Joining the French Geological Survey (BRGM) means becoming part of France's leading public institution for Earth Science applications bringing together 1,000 wholeheartedly committed experts across 29 bases in Mainland and Overseas France.

BRGM focuses on enhancing geological knowledge and understanding of surface and sub-surface-related phenomena, with a view to meeting the challenges of environmental changes through innovative projects with societal implications.

In hydrogeology, an underground physical barrier (UPB) refers to a low-permeability screen constructed across the flow of groundwater with the aim of modifying underground flows and piezometry and, where applicable, mitigating saline intrusion.

This term covers a wide variety of types of structures, desired effects, hydrogeological configurations, and implementation difficulties.
UPB are also constructed in other contexts with other objectives, such as construction, contaminated sites and soils, mining, etc.

For decades, UPB, sometimes called “underground dams,” have been widely used in countries facing sharp seasonal contrasts in precipitation that lead to long periods of drought (Japan, China, Brazil, etc.).

These structures are mainly used to store water that would otherwise have simply passed through the territory or to protect groundwater resources from saline intrusion in coastal areas.

A country such as Turkey has built more than a hundred modern UPB over the past decade, and scientific and technical publications on the subject are growing rapidly worldwide.

The water stored in this way is used for agricultural purposes and to supply drinking water.

BRGM is currently conducting transdisciplinary scientific research project aimed at studying UPB from various topics (hydrogeological, technological, environmental, regulatory, economic, and societal) in order to define their scope and potential applications in France, particularly in the context of climate change and pressure on water resources. A collaboration with a civil works contractor is planned.


You will be primarily responsible for:
- State of the art, bibliography ;
- Analysis of the application fields for each process;
- Discussions with civil works contractors ;
- Design methods for the various processes and corresponding geological, geotechnical, and hydrogeological investigation requirements; Identification of functional, technical, performance, economic criteria, goals and indicators for classifying/comparing UPB methods.

Development of a comparison multicriteria method.

For the solutions emerging from this analysis, development of preliminary design at one to three documented real sites:
- definition, monitoring, and interpretation of the geotechnical reconnaissance program;
- selection of technical scenarios;
- preliminary design of the technical solution(s);
- evaluation of costs/phasing/execution rates.

Drafting and submission of at least one publication in peer-reviewed scientific journals.
