Aude explores karst formations to increase Orbieu river flow

Studies are underway to explore using Orbieu's karsts to bolster the river's flow amid persistent drought. The Aude region's water management authority began research in 2023 on these underground water formations, hoping to increase the river's volume. The Orbieu has faced severe water restrictions for years due to significant deficits. Previous studies confirmed the Orbieu's water imbalance. New research aims to quantify water exchange between the river and karst systems, potentially using high-water losses to recharge springs and support summer flow.
