Use restriction

Updated on 06/09/2018
Définition
Sens réglementaire
Exceeded limits lead to restrictions of use and water withdrawal, to cope with a shortage of water resources during low water periods. Restriction measures are defined locally by the prefects. Generally, measures to limit withdrawals are progressive (depending on the thresholds defined for vigilance, alert, quick reaction alert or crisis) and adapted to different uses (domestic, agricultural, industrial).

Charges/fees for water abstraction/withdrawal

Updated on 06/09/2018
Définition
Sens commun
Amount of money due for water withdrawals, regardless of the user (municipality, industry, farmer) according to specific thresholds. This fee usually has two components: one based on the amount of water withdrawn, the other on the amount of water consumed (i.e. taken and not returned to the natural environment).

Charges/fees for water storage during low-water periods

Updated on 06/09/2018
Définition
Sens technique
Amount of money paid by people who store all or part of the volume flowing into a river during low water periods (provided that the capacity of the facility is greater than one million cubic meters). The amount of this fee depends on a rate and a basis, the latter being the volume of water stored during the low water period. The period and the rate are defined by the river basin authorities, according to the hydrological regime of the river.

Water resource

Updated on 02/03/2021
Définition
Sens technique

Source potentielle d'approvisionnement en eau permettant de satisfaire des besoins en eau liés à certaines activités humaines, par l’intermédiaire d’actions de prélèvements réalisés à partir d’ouvrages de prélèvement. Certaines ressources en eau peuvent être, dans une certaine mesure, considérées comme étant de nature artificielle, dès lors que leur répartition territoriale émane d’une intervention humaine (exemple : plan d’eau artificiel, bras d’eau artificiel,…). Le suivi des pressions exercées par les prélèvements d’eau est réalisé à la fois au niveau des ressources naturelles, mais aussi artificielles.

En tenant compte des concepts ayant été définis dans le cadre de la mise en place du Système d’Information sur l’Eau (SIE), une ressource en eau peut correspondre à l’un des concepts suivants :

  • un cours d’eau (cours d’eau naturel ou aménagé, un bras naturel ou aménagé, un canal,…), ·
  • un plan d’eau y compris citerne, réservoir ou bassin de stockage, ...
  • une entité hydrogéologique,
  • une mer / un océan

Warning level (or threshold) flow

Updated on 13/07/2018
Définition
Sens technique

"Threshold" value of the flow that triggers the first restrictions for some activities. These measures are taken at the initiative of the prefectural authority in connection with a crisis cell and in accordance with a crisis plan. Below this threshold, one of the functions (or activities) is compromised. To partially restore this function, it is necessary to limit temporarily another: withdrawal or discharge (first restriction measures)…

according to OFB
Sens technique

Warning issued in advance by a special state service (flood forecasting service). In the event of a rainfall or hydrological alert (triggering when thresholds are exceeded), the flood forecasting service offers the Prefect the alert of the mayors of the watersheds concerned. As a severe overflow flood, the flood warning service broadcasts, for prefects and mayors, hydrological situation bulletins and information on the evolution of water levels . In 1994, 54 flood warning services monitored 16,000 km of waterways in France using automated measurement networks.
