Sediment traps with open check dams are widely used structures in flood hazard mitigation. This paper reviews the literature dedicated to their design. First, general context which sediment built and functions presented. The second part proposes hydraulic design criteria for classical types details on opening shapes dam crest spillway. third deposition dynamics: its initiation, controls through trap basin shapes, effect of hydrographs, control self-cleaning. methods determine deposit slope...
Abstract For more than 150 years, humans have tried to limit the geomorphic activity of mountain streams, and related damage, using torrent control works. Check dams are likely most emblematic civil engineering structures used in soil conservation programs. Modern societies inherited thousands these built upland gullies streams. To help define their effectiveness decisions concerning maintenance or new project designs, a clear understanding potential effects check on river systems, i.e....
Sediment traps with open check dams are widely used structures in flood hazard mitigation. This paper and its companion review the literature on their design. The examines hydraulic deposition processes associated sediment transport. However, field feedback has shown that dam behaviors during floods dramatically influenced by presence or absence of driftwood. To better assess large woody debris hazards influences, this first reports methods available to estimate driftwood production terms...
In humans, the clinical and molecular characterization of sporadic syndromes is often hindered by small number patients difficulty in developing animal models for severe dominant conditions. Here we show that availability large data sets whole-genome sequences, high-density SNP chip genotypes extensive recording phenotype offers an unprecedented opportunity to quickly dissect genetic architecture conditions livestock. We report on identification seven de novo mutations CHD7, COL1A1, COL2A1,...
Abstract Bedload and river morphology interact in a strong feedback manner. conditions the development of along different space time scales; however, by concentrating flow preferential paths, given controls bedload for discharge. As is non‐linear response shear stress, local likely to have impact on prediction when stress averaged over section, as usually done. This was investigated comparing measured bed morphologies (step‐pool, plane bed, riffle‐pool, braiding, sand beds), with narrow...
River widening, defined as a lateral expansion of the channel, is critical process that maintains fluvial ecosystems and part regular functioning rivers. However, in areas with high population density, channel widening can cause damage during floods. Therefore, for effective flood risk management it essential to identify river reaches where abrupt may occur. Despite numerous efforts predict most studies have been limited single rivers events, which not be representative other conditions....
TNF-α is a potent proinflammatory cytokine that regulates immune and inflammatory responses programmed cell death. stimulation causes nuclear translocation of several NF-κB dimers, including RelA/p50 RelB/p50. However, contrary to RelA, RelB entering the nucleus in response cannot bind DNA mouse embryonic fibroblasts, strongly suggesting DNA-binding activity modulated by additional mechanisms. Here, we demonstrate promotes association RelA with TNF-α-induced RelA/RelB heterodimers do not κB...
ABSTRACT In poorly mobile static armour, sorting is usually considered the result of hiding/exposure effects. We called this effect ‘static sorting’ in opposition to very efficient grain‐to‐grain mechanisms produced by a mixture, ‘kinetic sorting’. hypothesized that kinetic can be an important contributor morphodynamics mountain streams and attempted demonstrate with new flume experiments. Two long runs were natural sorted sediments, transport stages coarse fraction (defined ratio between...
Abstract In bedload transport modelling, it is usually presumed that transported material fed by the bed itself. This may not be true in some mountain streams where can very coarse and immobile for majority of common floods, whereas a finer material, supplied bed‐external sources, efficiently during with marginal morphological activities. mode was introduced an earlier paper as ‘travelling bedload’. It could considered extension washload concept suspension, applied to high‐energy, heavily...
Abstract Large boulders can jam in constrictions, both canyons and man‐made structures (e.g., slit‐dams). Boulder jamming occurs stochastically, partially governs the outflow rate of debris flow material. Explicit hydro‐mechanical models boulder‐laden flows are too computationally demanding to study this stochasticity. This presents a new framework implemented into numerical program. program encapsulates basic hydraulic equations criteria predicting boulder blockage at narrow sections, along...
Economic narratives are largely put forward as an argument for the promotion of Nature Based Solutions (NBS). However, integrated economic evidence, taking into account direct and opportunity costs, avoided damages multiplicity co-benefits generated by NBS still needed to support this convince decision makers invest in these solutions. To address gap, we develop a methodological framework assessment water related risks present its application three European case studies. We find that cost...
Abstract. Open check dams are strategic structures to control sediment and large-wood transport during extreme flood events in steep streams piedmont rivers. Large wood (LW) tends accumulate at such structures, obstruct their openings increase energy head losses, thus increasing flow levels. The extent variability which the stage–discharge relationship of a dam is modified by LW presence has so far not been clear. In addition, sufficiently high flows may trigger sudden release trapped with...
Radio-enhancement is a promising anti-cancer approach based on local radiation dose increase due to the presence of metallic nanoparticles (NPs) within cancer cells. Depending their composition, size and cellular properties, NPs can follow multiple pathways entry routes. We observed that gold, platinum TiO2 are internalized at higher levels in mesenchymal cells compared epithelial breast models. A global survey gene expression between exposed 4 different NP types revealed an involvement...
Extreme rainfall events in mountain catchments can induce substantial geomorphic changes, reshaping channels, hillslopes, and surrounding environments. These changes often widen active recruiting large wood from adjacent forests into sediment-laden flows, thereby increasing hazards such as altered flow patterns, sediment retention, logjam formation. Such dynamics exacerbate flood risks, particularly near infrastructure like bridge piers, dams weirs. Understanding the extent of forest areas...
Abstract As interest mounts in nature‐based solutions (NBS) for flood mitigation as complementary options to civil‐engineering measures, possible flood‐protection strategies have become more diverse and hence complicated assess. We offer a straightforward educational protocol targeted effectiveness analysis decision making involving stakeholder participation. It is based on the concept of flood‐excess volume (FEV), exceeding threshold generating damage, explores what fraction FEV reduced, at...
Abstract Steep streams with massive sediment supply are among the most complex systems to study, even in laboratory. Their shallow sediment‐laden flows create self‐adjusting bed geometries that evolve rapidly. Often, morphological changes and flow processes cannot be dissociated. Because these very unstable equipped measurement sensors, image analysis techniques, such as photogrammetry (e.g., structure‐from‐motion, SfM) large‐scale particle velocimetry (LSPIV), interesting options for...
Abstract. This paper presents a methodology to analyse debris flows focusing at the surge scale rather than full of debris-flow event, as well its application French site. Providing bulk features like volume, peak discharge, front height, velocity and Froude numbers allows for numerical experimental investigations be designed with narrower physical ranges thus deeper scientific questions explored. We suggest method access such that can applied wide variety monitoring stations. Requirements...
