Assessing Surface Water and Groundwater Interactions Using Long-Term Hydrological and Time-Lapse Seismic Data in the Orgeval Critical Zone Observatory

Quantifying the water and heat fluxes at the interface between surface water (SW) and groundwater (GW) is a key issue for hydrogeologists to consider for safe yield and good water quality. However, such quantification with field measurements is not straightforward because the SW-GW changes depend on the boundary conditions and the spatial description ...

Spatial and temporal variability of structure and hydric properties of topsoil from the Orgeval catchment (Brie, France)

1996
L'organisation spatiale et l'hétérogénéité des caractéristiques texturales, structurales, hydriques des sols et leur évolution temporelle jouent un rôle majeur sur le fonctionnement des bassins versants. Leur description et l'analyse des relations structure-transfert permettraient en partie de prévoir les flux des pollutions et les crues.

Active microwave remote sensing and soil superficial water content. The Agriscatt'88 airborne campaign on the Orgeval watershed

1991
Après avoir présenté les objectifs de la campagne radar aéroportée AGRISCATT'88, organisée par l'Agence Spatiale Européenne, on décrit les expériences réalisées en France, sur le bassin versant représentatif et expérimental de l'Orgeval avec le diffusomètre ERASME.

Use of High Frequency measurements to better determine the concentration-flow relationship (CQ) of the Avenelles watershed (ORGEVAL Critical Zone Observatory)

2018
The Water Framework Directive (DCE 2000/) shows an ambition to regain the good ecological status of water bodies. In France, two types of water quality indicators are currently evaluated: annual concentrations (arithmetic mean, median, upper quantile, flow-weighted averages) that are reported in a quality grid (SEQ -Water) and the annual flows ...

Chemical weathering in a multi-layer aquifer-dominated watershed under intensive agriculture conditions: the Orgeval Critical Zone Observatory, France

2018
Extensively instrumented and monitored over the last 50 years, the Orgeval Critical Zone Observatory in France is an observation site in a landscape impacted by agriculture and more importantly since the 1960's. Rivers from the Orgeval watershed are typical multi-layer aquifer fed rivers in a sedimentary basin context.
