The rain returned to France on Sunday 14 August and Monday 15 August. H2o additional than welcome after months of drought at the end of a really dry winter. In several regions of the nation, the aquifers are at extremely small levels. This is the case of Provence, the French Riviera or Poitou. Sunday, all departments in mainland France had been on drought notify, together with 22 on “superior warn” and 68 on “crisis”, the best warn level. In July, less than a centimeter of drinking water fell in mainland France, so thunderstorms followed by precipitation ended up especially envisioned.

“We have flows from some of our springs which in this period are halved in comparison to flows that are not extremely significant in July-August“, observes Laurent Lucaud, elected communist and vice president of Better Poitiers in charge of drinking water and sanitation. On Sunday and Monday it rained much less than 15 millimeters in all respects, “just a small thunderstorm“, feedback the elected formal. The level of tablecloths in Poitou is low, even regionally pretty low.Ought to, he proceeds, that there is a reasonably great and abundant rainfall, for several weeks, even many months, in buy to fill the water deficit“. Due to the fact the deficit is counted in”hundreds of hundreds or even hundreds of thousands of cubic meters“all through the Poitevin territory.
Especially considering that it is not the summer months rains that recharge the aquifers but fairly the autumn and winter season rains. “The rains address the issue of soils and crops. The ground is in first place versus the rain, it is he who works by using it 1st. This will allow for a resumption of plant lifestyleand, he clarifies Vazken Andreassian, hydrologist. But on the other hand, the aquifers have to wait around: they are made use of very last“.
“The aquifers are instead reconstituted during the winter season, when the soils are now virtually saturated. If the latest rains make it achievable to clear up the trouble of rivers on the surface area, the aquifers continue to have to wait”.

Yet another issue, the hydrologist points out: the extraordinary drought of the soil. The subsequent rain episodes guarantee to be short but violent. Gold, youthe mainland does not take in the ample water of storms. “Really major rains do not profit the soil or aquifers, simply because there is a runoff phenomenon, which can create flooding.“, inform Vazken Andreassian
Eyes hence focused on autumn and the starting of wintertime with important rainfall envisioned to ensure the source of drinking water. The breaking place is not much away all around Poitiers, assures Laurent Lucaud: “Our reserves are dwindling each and every working day. If the absence of drinking water is additional to this present disaster, the deficit will maximize. We are by now on the reservation of the reservation“. According to vice president of Bigger Poitiers, of “interruptions in the provide of consuming drinking water in a period of time from November to December, this is unheard of“.
The situation is superior in other regions of France. In the north, in the Paris basin or in the Pyrenees, the aquifers have a standard stage, all-around the average.
