Dem’Eaux 2021 Webinar: improving understanding of the Roussillon coastal aquifer

The aim of the Dem’Eaux Roussillon project is to gain a better understanding of the volumes of water that can be sustainably abstracted from the Roussillon coastal aquifer. A webinar was organised on 11 and 12 March 2021 to present the initial results of this project.

Presentations

(L. Seguin, N. Neverre, M. Montginoul, P. Garin, J.D. Rinaudo)

• Demand for agricultural and drinking water: what is known and what is missing?
• Can we optimise water use in relation to resources through a hydro-economic modelling exercise?
• Integration of scientific and technical knowledge in territorial water management planning processes

Presentations

(F. Bouchette, F. Meslard, F. Bourrin, Y. Balouin, M. Assembaum)

• Propagation of marine weather signals in the coastal aquifer: taking better account of marine factors in hydrodynamic groundwater modelling
• Interaction between the transport of solids and coastal morphology in the Têt river mouth area under variable/extreme climatic conditions
• Development of new measurement and observation systems on the Roussillon coastline

Presentations

(S. Lanini, C. Duvail, Y. Caballero)

• Geometry of terrestrial and marine Quaternary and Pliocene formations and geological modelling
• Relationships between canals, water tables and rivers on the upper Têt and implications for the recharge of the Pliocene-Quaternary aquifer
• Hydrodynamic terrestrial-marine modelling of the Roussillon Pliocene-Quaternary aquifer

Presentations

(J.-B. Raynaud, Y. Caballero)

• Presentation of the Follow Roussillon platform and its features
• Debate on prospects for use in the area
• Schedule of future action and closure of the webinar
