Compenser la destruction de zones humides. Retours d’expérience sur les méthodes et réflexions inspirées par le projet d’aéroport de Notre-Dame-des-Landes (France) [PDF]

open access: yesNatures Sciences Sociétés, 2015
Début 2013, les auteurs de cet article ont été conjointement sollicités par l’État pour donner un avis sur la méthode de compensation des atteintes aux zones humides proposées pour le projet d’aéroport du Grand Ouest à Notre-Dame-des ...

Improving hydroacoustic methods for monitoring suspended‐sand flux and grain size in sediment‐laden rivers

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 1, January 2025.
Single‐ and dual‐frequency hydroacoustic methods were validated in an Alpine river with a bimodal silt–sand suspension using a large and precise dataset. Adapted methods provided good suspended‐sand concentration estimates but limited additional grain‐size information compared with that from the physical samples.

Probabilistic flood forecasting on the Rhone River: evaluation with ensemble and analogue-based precipitation forecasts

open access: yesE3S Web of Conferences, 2016
Hydrological ensemble forecasting performances are analysed over 5 basins up to 2000 km2 in the French Upper Rhone region. Streamflow forecasts are issued at an hourly time step from lumped ARX rainfall-runoff models forced by different precipitation ...

The impact of physical processes on algal growth [PDF]

open access: yes, 1992
Mixing and transport processes in surface waters strongly influence the structure of aquatic ecosystems. The impact of mixing on algal growth is species-dependent, affecting the competition among species and acting as a selective factor for the ...

Learning Regionalization Using Accurate Spatial Cost Gradients Within a Differentiable High‐Resolution Hydrological Model: Application to the French Mediterranean Region

open access: yesWater Resources Research, Volume 60, Issue 11, November 2024.
Abstract Estimating spatially distributed hydrological parameters in ungauged catchments poses a challenging regionalization problem and requires imposing spatial constraints given the sparsity of discharge data. A possible approach is to search for a transfer function that quantitatively relates physical descriptors to conceptual model parameters ...

Buckling Analysis of Embedded Nanosize FG Beams Based on a Refined Hyperbolic Shear Deformation Theory [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2018
In this study, the mechanical buckling response of refined hyperbolic shear deformable (FG) functionally graded nanobeams embedded in an elastic foundation is investigated based on the refined hyperbolic shear deformation theory.

Conjunctive use of floodwater harvesting for managed aquifer recharge and irrigation on a date farm in Morocco

open access: yesIrrigation and Drainage, Volume 73, Issue 4, Page 1424-1436, October 2024.
Abstract In arid regions, harvesting floodwater can mitigate irrigation‐induced groundwater depletion by providing additional surface water and recharging aquifers. We designed an experimental protocol to quantify these fluxes on a date farm located along the Wadi Satt, whose flow originates from the Anti‐Atlas Mountains in south‐eastern Morocco ...
