National Park

Updated on 06/09/2018
Définition
Sens commun
Remarkable area of the territory that has been classified as "National Park & nbsp;" because of its exceptional natural wealth, from the point of view of landscape quality and natural, historical or cultural heritage.

Regional natural park

Updated on 06/09/2018
Définition
Sens commun
A vast area where the community stakeholders look for a development respectful of the natural balances, and sometimes a solution for maintaining declining traditional activities. A regional natural park (RNP) is usually managed by a public inter-municipal cooperation organisation, an open mixed syndicate whose board of directors is composed of elected representatives of the member communities (municipalities, departments, regions) and sometimes socio-economic partners. PNRs are classified for a 12-year renewable period.

Green and Blue Habitat network

Updated on 06/09/2018
Définition
Sens technique
Network consisting of terrestrial ecological ("green" habitat) and aquatic ("blue" habitat) continuities, especially identified in regional ecological coherence schemes (RECS). The green and blue habitats (GBH) contribute to the enabling conservation status of natural habitats and species and to the good ecological status of water bodies, as well as to maintain the services that biodiversity provides (water quality, pollination, flood prevention, improvement of the living environment, etc.). It extends to the transversal limit of the sea. The GBH is a tool of sustainable development and regional planning, with the master plans for water development and management (SDAGE). It is also a tool for preserving biodiversity, combined with all the other existing tools: protected areas, national parks, nature reserves, biotope protection decrees, Natura 2000, regional natural parks, national action plans for endangered species, etc.) under the 2011-2020 National Biodiversity Strategy.

Biotope protection order

Updated on 18/03/2020
Définition
Sens technique

Order established by the department prefect to implement measures to conserve biotopes such as ponds, marshes, swamps, heathland, dunes, groves, hedgerows, lawns and any natural formation not exploited by humans since these biotopes are necessary for reproduction, feeding, rest, survival of protected species. The biotope protection order is particularly adapted to deal with emergency situations of destruction or significant modification of an area.

Water abstraction

Updated on 25/02/2019
Définition
Sens commun

Extraction of fresh water from a groundwater source or surface, permanently or temporarily, and conveyed to the place of use.

Flood warning

Updated on 08/04/2020
Définition
Sens commun

Warning issued in advance by the departmental flood forecasting services. In the event of heavy rainfall or hydrological alert, a flood warning is sent to the Prefect, who then alerts the mayors of the catchment areas concerned.

Source
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.

Dam release

Updated on 06/09/2018
Définition
Sens technique
Operation to lower water level and increase outflow rates to discharge some of the sediment retained by a dam. A dam release consists in opening the gates, thus limiting the silting of the dam reservoir and the risk of flooding. This operation, although common in the management of harnessed rivers, can have adverse effects on the downstream environment (decrease of oxygen levels in water, obstruction of fish gills by suspended solids, etc.).

Groundwater/river exchange

Updated on 06/09/2018
Définition

Silting

Updated on 06/09/2018
Définition
Sens technique
Deposit of fine sediments made of rock particles and silt or clay. Siltation is a form of sedimentation with mud. Streams carry a few million cubic meters of sediment each year. Their deposit causes the silting of these rivers, canals, and bodies of water. This quite natural phenomenon is accentuated by a flat topography, low flows, erosion processes, as well as industrial and urban discharges.
