摘要: The impact of glaciation cycles on groundwater flow was studied within the framework nuclear waste storage in underground geological formations. eastern section Paris Basin (a layered aquifer with impervious/pervious alternations) France considered for last 120 ka. Cold periods corresponded arid climates. issue talik development below water bodies addressed. These unfrozen zones can maintain open pathways recharge. Transient thermal evolution simulated a small-scale generic unit landscape including “river” and “plain”. Coupled thermo-hydraulic modeling simplified conductive heat transfer were broad range scenarios. results showed that when considering current limited river dimensions purely transfer, taliks are expected to close few centuries. However, coupled advection flows from plain (probably pertinent recharge zones) strongly delays closure (millennium scale). regional is vary complete stop reduced recharge, corresponding zones. Consequences future approaches discussed.
