Abstract. Climate and land use changes, as well human water flow alteration, are causing worldwide shifts in river dynamics. During the last decades, low flows, intermittence, drying have increased many regions of world, including Europe. This trend is projected to continue amplify future, resulting more frequent intense hydrological droughts. However, due a lack data studies on temporary rivers past, little known about processes governing development intermittence drying, their timing...
Abstract. Vegetative filter strips are often used for protecting surface waters from pollution transferred by runoff in agricultural watersheds. In Europe, they prescribed along the stream banks, where a seasonal shallow water table (WT) could decrease buffer zone efficiency. spite of this potentially important effect, there no systematic experimental or theoretical studies on effect soil boundary condition VFS companion paper (Muñoz-Carpena et al., 2018), we developed physically based...
The migration and fate of pesticides in natural environments is highly complex. At the hillslope scale, quantification contaminant fluxes concentrations requires a physically based model. This class model has recently been extended to include coupling between surface subsurface domains for both water flow solute transport regimes. Due their novelty, relative importance interactions main parameters not yet fully investigated. In this study, global Sobol sensitivity analysis performed on...
Abstract. Vegetation buffers like vegetative filter strips (VFSs) are often used to protect water bodies from surface runoff pollution disturbed areas. Their typical placement in floodplains results the presence of a seasonal shallow table (WT) that can decrease soil infiltration and increase pollutant transport during rainfall-runoff event. Simple robust components hydrological models needed analyze impacts WT landscape. To simulate VFS under realistic rainfall conditions with WT, we...
Abstract The knowledge of historical French weather has recently been improved through the development Spatially COherent Probabilistic Extended (SCOPE) climate reconstructions. This high‐resolution ensemble daily reconstruction dataset precipitation and temperature covers period 1871–2012 is derived a statistical downscaling Twentieth Century Reanalysis. Historical surface observations – even though rather scarce sparse do exist from at least beginning considered, this information does not...
Abstract. Surface observations are usually too few and far between to properly assess multidecadal variations at the local scale characterize historical extreme events same time. A data assimilation scheme has been recently presented assimilate daily of temperature precipitation into downscaled reconstructions from a global extended reanalysis through an Ensemble Kalman fitting approach derive high-resolution fields. Recent studies also showed that assimilating high temporal resolution does...
Selected runs with a physics-based model of surface water–groundwater interactions are used to examine in detail some numerical challenges and surprising behaviors that result from discretization, nested solution schemes, coupling, boundary condition, other factors. Regardless the spatial scale domain (field, hillslope, catchment, …), processes simulated by this class integrated models can exhibit widely varying dynamics within across different subsystems comprising land surface, unsaturated...
River networks are among Earth’s most threatened hot-spots of biodiversity and provide key ecosystem services (e.g., supply drinking water food, climate regulation) essential to sustaining human well-being. Climate change increased use causing more rivers streams dry, with devastating impacts on services. Currently, than a half the global river consist drying channels, these expanding dramatically. However, (DRNs) have received little attention from scientists policy makers, public is...
Abstract. The recent development of FYRE (French hYdroclimate REanalysis) Climate, a high-resolution ensemble daily reanalysis precipitation and temperature covering the 1871–2012 period whole France, offers opportunity to derive streamflow series over country from 1871 onwards. Climate dataset has been used as input for hydrological modelling large sample 661 near-natural French catchments using GR6J (Génie Rural à 6 Paramètres Journaliers) lumped conceptual model. This approach led...
ABSTRACT Numerical models are essential for comprehending intricate physical phenomena in different domains. To handle their complexity, sensitivity analysis, particularly screening is crucial identifying influential input parameters. Kernel‐based methods, such as the Hilbert‐Schmidt Independence Criterion (HSIC), valuable analyzing dependencies between inputs and outputs. Implementing HSIC requires data from original model, which leads to need of efficient sampling strategies limit number...
