E-TEST Einstein Telescope EMR Site: cross-border hydrogeological model

The hydrogeological model developed within the framework of the E-TEST project must make it possible to answer 3 principal objectives:
1) to globalize the information available regionally on the hydrogeological functioning of the study area and to obtain a better understanding of the hydrogeological functioning of the aquifers
2) to quantify the volume of water that it will be necessary to drain in the galleries of the telescope and then pump it out of the site. These estimates will directly result in the dimensioning of the drains and pumps to ensure these operations without disturbing the functioning of the device. In order to provide a satisfactory answer to this question, it is necessary to take into account local scale phenomena such as faults in the vicinity of the site and the telescope elements.
3) to quantify the potential influence of these drainages on the aquifers of the area located at the border between the Fourons region, Wallonia and the south of the Dutch Limburg Province.
