Validation of a Rough Surface Model Based on Fractional Brownian Geometry with SIRC and ERASME Radar Data over Orgeval

Remote Sensing of Environment, 2000
During the 1994 SIRC/XSAR mission, part of the scientific activities were devoted to hydrology applications. To complement the shuttle radar data, the helicopter scatterometer ERASME was used on the Orgeval site. As a result, incidence angles ranging from 25° to 57° are available in the C band.

Backscattering behavior and simulation comparison over bare soils using SIR-C/X-SAR and ERASME 1994 data over Orgeval

Remote Sensing of Environment, 1997
During April 1994, the three-frequency radar system flew on the Space Shuttle Endeavour, known as SIR-C/X-SAR mission (Shuttle Imaging Radar C/X-Synthetic Aperture Radar). Over the Orgeval watershed (France), the ground condition stayed very wet throughout the 5-day SAR mission.

Chemical weathering and CO₂ consumption rate in a multilayered‐aquifer dominated watershed under intensive farming: The Orgeval Critical Zone Observatory, France

Hydrological Processes, 2018
AbstractThe impact of intensive farming on chemical weathering in the Critical Zone is still an open question. Extensively instrumented and monitored over the last 50 years, the Orgeval Critical Zone Observatory (CZO) in France is an observation site impacted by intensive farming since the 1960s.

Integrating Data into the Hydrogeophysical Model: A Case Study of 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 ...

Water and energy fluxes at the surface- subsurface interface of the ORACLE/BVRE Orgeval Observatory

2017
Accurately quantifying surface-subsurface water and energy fluxes is challenging because a myriad of morphological and physical factors subject to spatial and temporal variability, and nested interfaces, lead to patterns in residence time over multiple spatial scales.

The Orgeval experimental research basin: a tool to analyse hydrological behaviours and impact of changes

2003
Sur ce poster, nous montrons qu'il est nécessaire d'avoir des signaux hydrologiques issus de bassin purs (agricultural et forestier) pour représenter le signal hydrologique de bassin versant mixte et que changer d'échelle change les relations : pour une bonne modélisation du signal hydrologique mixte d'ordre 3 à l'aide de bassins purs et /ou mixtes d ...

Summary of research done in watershed of Orgeval, Grand Morin affluent, about streaming-erosion topic

2002
Cette étude a été réalisée pour le Syndicat intercommunal du Grand Morin, dans le cadre d'une étude visant à lutter contre les ruissellements urbains et ruraux et à limiter la contribution des bassins versants et des rus à la montée des eaux. On y présente les caractéristiques générales du bassin, les caractéristiques pluviométriques et hydrologiques ...

(trad auto)Publication and transfer of pesticides: example of the Orgeval catchment area

1978
L'étude concerne l'éution et le transfert des pesticides durant un cycle cultural et un cycle hydrologique sur le bassin versant de l'Orgeval, bassin expérimental situé en région de grandes cultures (Brie), dans un secteur où l'utilisation des pesticides est abondante.
