The winter recharge was effective in the first few months of 2016. By 1 April, 76% of the underground reservoirs were at a satisfactory level. Most of the Paris Basin, the South-West and Eastern France had levels that were normal or above normal, due to heavy rainfall. In March, for example, there was a rainfall surplus of more than 20% over the whole country. Some sectors nevertheless still had a recharge deficit, such as parts of South-East France and to the north-east of the Paris Basin.
Aiming for active groundwater management
One of the challenges of active groundwater management is to compensate for chronic deficits in certain aquifers. This can be done, for example, using artificial techniques to recharge reservoirs. Faced with a potential drop in recharge due to climate change, BRGM is providing scientific support for this active management, which aims to better reconcile water supply and demand.
