In large-scale aquatic ecological studies, direct habitat descriptors (e.g. water temperature, hydraulics in river reaches) are often approximated by coarse-grain surrogates air discharge respectively) since they easier to measure or model. However, as biological variability can be very strong at the scale, surrogate variables may have a limited ability capture all of this variability, which lead lesser understanding processes patterns interest. study, we aimed compare capacity vs....
Abstract Approaches available for estimating the ecological impacts of climate change on aquatic communities in river networks range from detailed mechanistic models applicable locally to correlative approaches globally. Among them, hydraulic habitat (HABMs) link streams with biological that reflect how organisms select microhabitat hydraulics. Coarser but more general species distribution (SDMs) predict changes geographic distributions; they generally involve coarse predictors such as air...
Abstract. The ability to understand and predict coarse sediment transport in torrent catchments is a key element for the protection prevention against associated hazards. In this study, we collected data describing supply at 99 torrential Northern French Alps. sample covers wide range of geomorphic activity: from torrents experiencing debris flows every few years fully forested exporting small bedload volumes decade. These have long records past events basins. mean annual, 10-year return...

Abstract Reach‐scale at‐a‐station hydraulic geometry (AHG) relationships are power laws that describe variations of reach‐averaged water depth, wetted width, and current velocity in stream reaches when discharge varies. Modeling AHG exponents is important, because the hydraulics with networks influence physical habitats aquatic species, biodiversity, temperature, nutrient fluxes, sediment transport. Theoretical approaches indicated should depend on topographic descriptors cross sections...

The ability to understand and predict sediment transport in torrent catchments is a key element for the protection prevention against associated hazards. In this study, we collected data describing supply at 100 torrential Northern French Alps. These have long records of past events due debris deposition basin management enabling estimation frequency. mean annual, 10-year return period reference volume (i.e. 100-year level or largest observed volume) were derived studied torrents. We...
<p>In mountain areas, the quantification of sediment yield is essential in diagnosis a torrential watershed. The objective this study to present prediction method based on multivariate statistical models calibrated from an original data set covering nearly 130 basins Northern French Alps. Data and occurrence events were collected these catchments thanks registries retention (average monitoring period 20 years) historical archives catchment basin managers. On catchments, several...
