Abstract The Surface Water and Ocean Topography (SWOT) satellite mission planned for launch in 2020 will map river elevations inundated area globally rivers >100 m wide. In advance of this launch, we here evaluated the possibility estimating discharge ungauged using synthetic, daily “remote sensing” measurements derived from hydraulic models corrupted with minimal observational errors. Five algorithms were evaluated, as well median five, 19 spanning a range geomorphic conditions. Reliance...
Fifty years after the hyporheic zone was first defined (Orghidan, 1959), there are still gaps in knowledge regarding role of biodiversity processes. First, some methodological questions remained unanswered interactions between and physical processes, both for study habitat characteristics at different scales. Furthermore, many remain to be addressed help inform our understanding invertebrate community dynamics, especially trophic niches organisms, functional groups present within sediment,...
Abstract Bioclogging in rivers can detrimentally impact aquifer recharge. This is particularly so dry regions, where losing are common, and disconnection between surface water groundwater (leading to the development of an unsaturated zone) occur. Reduction riverbed permeability due biomass growth a time‐variable parameter that often neglected, yet reduction from bioclogging introduce order magnitude changes seepage fluxes over short (i.e., monthly) timescales. To address combined effects on...
Abstract Rivers in climatic zones characterized by dry and wet seasons often experience periodic transitions between losing gaining conditions across the river‐aquifer continuum. Infiltration shifts can stimulate hyporheic microbial biomass growth cycling of riverine carbon nitrogen leading to major exports biogenic CO 2 N rivers. In this study, we develop test a numerical model that simulates biological‐physical feedback zone. We used explore different initial terms dissolved organic...
Abstract The footprint of catchment properties on water flow is reflected into hydrological signals, such as stream discharge. Here we demonstrate that it possible to constrain from the spectral analysis signals but only when an appropriate transfer function (TF) used for interpretation. We show theoretical TF, newly derived, one robustly describe a large diversity experimental TFs could be encountered in nature, because entails role diffuse overflow and through vadose zone, which have never...
Abstract. Coupled hydrological-hydrogeological models, emphasising the importance of stream–aquifer interface, are more and used in hydrological sciences for pluri-disciplinary studies aiming at investigating environmental issues. Based on an extensive literature review, interfaces described five different scales: local [10 cm–~10 m], intermediate [~10 m–~1 km], watershed km2–~1000 km2], regional 000 km2–~1 M km2] continental scales [>10 km2]. This led us to develop concept nested...
This study aims at analyzing the water budget of unconfined Beauce aquifer (8000 km 2 ) over a 35 year period, by modeling hydrological functioning and quantifying exchanged fluxes inside system. A distributed process‐based model (DPBM) is implemented to surface, unsaturated zone subsystems. Based on an extensive literature review multiparameter optimization inverse problem, pragmatic hybrid fitting method that couples manual automatic calibration developed. Three data subsets are used for...
Abstract Assessment of the quality freshwater bodies is essential to determine impact human activities on water resources. The status estimated by comparing indicators with standard thresholds. Indicators are usually statistical criteria that calculated discrete measurements variables. If time step measured series not sufficient fully capture variable’s variability, deduced indicator may reflect system’s functioning. goal present work assess, through a hydro-biogeochemical modeling approach,...
Abstract. Seven Landsat thermal infrared (TIR) images taken over the period 2000–2010 were used to establish longitudinal temperature profiles of middle Loire River where it flows above Beauce aquifer. The groundwater discharge along river course was quantified for each identified catchment area using a heat budget based on variations estimated from TIR images. results showed that 75 % differences, between in situ observations and image-based estimations, remained within ±1 °C interval. main...
Abstract Fluvial networks play an important role in regional and global carbon (C) budgets. The Seine River, from the Paris urban area to entrance of its estuary (220 km), is studied here as example a large human‐impacted river system subject temperate climatic conditions. We assess organic C (OC) budgets upstream downstream one world's largest wastewater treatment plants for different hydrological conditions using hydrobiogeochemical model. fine representation sediment accumulation on bed...
