The catchment is the observation and experimental site of the Observatoire Hydro-Geochimique de l'Environnement appointed by the Centre National de la Recherche Scientifique. It also belongs to the research facilities that form the French Network of Critical Zone Observatories (OZCAR), which supports a network of critical zone observatories. The catchment is small (0.8 km(2)) with steep slopes (20-30%) on granitic bedrock that mainly allow for forestry (spruce and beech stands) as the main land cover. Meteorological, hydrological, and geochemical data have been monitored since 1986. The first studies conducted were dedicated to the elucidation of acid rain effects on forest ecosystems and particularly on forest decline. Multidisciplinary research studies conducted on the Strengbach catchment enable exploration of the following issues: (i) hydrological functioning at the scale of a small catchment and questions regarding the evolution and preservation of the water resources in mountainous environments (stock, recharge, infiltration, and water pathways), (ii) exchange processes observed at the soil-plant-atmosphere continuum and in particular weathering processes and the evolution of soil mineral fertility (Ca, Mg, K, P), (iii) processes responsible for the export of water and for associated fluxes (dissolved chemicals, suspended materials, bed loads) and their dynamic at the outlet, and (iv) responses of the ecosystems to environmental disturbances (acid rain, forest management, and climate change) and their current and future modeling. specialized FRANCE VOSGES 062 021 068 17 1 art. 180090 [17 p.] 2018 1539-1663 https://www.documentation.ird.fr/hor/PAR00018778 10.2136/vzj2018.04.0090 1539-1663 [F B010074845] https://www.documentation.ird.fr/hor/PAR00018778 https://www.documentation.ird.fr/intranet/publi/2019/01/010074845.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-02-04 2023-07-11 PAR00018778 fre
