Le secteur cévenol apparaît comme une zone prioritaire pour appréhender les ressources en eau. La présente convention complète les travaux précédents d'évaluation régulière des basses eaux pendant la période estivale, dans le cadre des programmes scientifiques Hydropop 1 & 2, portés successivement par l'UM ESPACE (Philippe Martin) et par l'IMT...

To estimate series of water flows, it is required to collect a set of reliable stream measures, as accurate as possible, and to generalize them using continuous water height measurement from immersed sensors. Many methods are used to do so such as gauging by salt for conductivity, velocimeter based on Dopler radar ultrasound to draw the river...

Dans le contexte cévenol qui induit un climat sec et chaud durant la période estivale et des pluviométries élevées et localisées durant l'automne, dues notamment à la combinaison entre la rencontre des masses d'air froides atlantiques et des masses d'air chaudes méditerranéennes combinées au soulèvement orographique induit par le massif des...

Convention et avenant en date du 4 juin 2018 entre le EPTB Gardons et Avignon université (UMR ESPACE) sur l'installation et le suivi de stations d'étiage dans les Gardons de 2018 à 2020.

The increase in the severity of hydrological droughts in the Mediterranean basin in relation to climate change leads to the need to better understand the origin of the water resource to improve its management. The defined study area, the Cevennes upper watershed of the Gardons, presents quite significant variations in terms of low water flows....

Concentration-discharge relationships have been extensively utilized to infer the routing of water and pathways of (bio)geochemical reactions in the Critical Zone. To date, relatively little complementary development of stable isotope ratio - discharge relationships has been made, despite the fact that these tracers are commonly used to...

In the Cévennes, in summer, water resources are rare. The gap between these resources and population needs generates local difficulties. Climate change (possible aridification…) and the evolution of lifestyles (increase in consumption, water for leisure activities…) may increase the problems in the future. Except for inter-basin transfers, the...

Mobilizing citizens for supporting research is a very widespread action in the field of natural sciences and particularly for obtaining data on the location and counting of plant and/or animal species. This practice is much less common for water resource observation.As part of this study, an online Webmapping platform wasdeveloped...

Le projet FloodScale est une contribution au programme international HyMeX (Hydrological Cycle in the Mediterranean Experiment). Il a pour objectif d'améliorer la compréhension et la simulation des processus hydrologiques conduisant à des crues éclair, qui sont l'un des risques naturels les plus destructeurs, notamment en région...
