BRGM contributes to the dialogue between science and society. To this end, it organises meetings in the regions, to provide opportunities for outreach and discussion. In Martinique, a meeting was held on 27 November 2018 in Saint Joseph.

As a public institution for research and expert studies, BRGM contributes to the dialogue between science and society in its different fields. 

Establishing a dialogue with civil society representatives in the French regions 

BRGM's regional representatives organise meetings with representatives of civil society groups to discuss regional environmental questions relating to BRGM's areas of expertise and on which papers and articles have been published. 

These meetings provide opportunities for open and constructive discussions. They stimulate exchanges of knowledge - or of knowledge "gaps” - questions from all parties and the expression of their expectations, while observing the ethical principles that guarantee transparency and trust and preserve the independent judgement of all concerned. 

Summary of the meeting held at Saint-Joseph on 27 November 2018 

Topic on the agenda 

Distinction between a perennial river and an intermittent river as defined in case law with the case study of the Rosière river at Saint Joseph.

The aims were: 

  • to describe the difficulty in interpreting the definition of a watercourse in the case law sense, especially in particularly heterogeneous contexts. 
  • to present the results of the study to define geomorphological indicators to characterise a watercourse (RP-67524-EN, 2018) 
  • to discuss a specific case known to the association and for which BRGM has carried out a field survey: namely, the status of the Rosière river in the municipality of Saint Joseph.
