Abstract A snow model forced by temperature and precipitation is used to simulate the spatial distribution of water equivalent (SWE) over a 600 000 km2 portion province Quebec, Canada. We propose improve simulations assimilating SWE data from sporadic manual surveys with particle filter. temporally spatially correlated perturbation meteorological forcing generate set particles. The magnitude perturbations fixed objectively. First, filter direct insertion were both applied on 88 sites for...

High-resolution climate change simulations over the Lesser Antilles are performed using ALADIN-Climate regional model nested within global ARPEGE (Météo-France). Three sets of conducted at 10 km grid spacing for reference (1971–2000) and future (2071–2100) under two CMIP5 scenarios (RCP4.5 RCP8.5). With dynamical downscaling, islands considered as land by model, whereas, driving there is only sea domain. Temperature precipitation analysed on separately. For temperature, warming greater than...

Extreme events are rarely observed, so their analysis is generally based on observations of more frequent values. The relevance the flood frequency (FFA) method depends its capability to estimate extreme values with reasonable accuracy using extrapolation. An FFA stochastic simulation event assessed reliability and stability. For such an assessment, different training/testing decompositions performed for a set data from than 1000 gauging stations. We showed that enables relevant 'predictive'...

La méthode SHYREG est une de prédétermination l'aléa hydrométéorologique extrême, basée sur la simulation des processus. Elle met en œuvre un générateur stochastique pluies horaires couplé à modélisation hydrologique suffisamment simplifiée pour être régionalisée. a été calée l'ensemble données hydrométéorologiques disponibles au niveau national (2800 pluviomètres Météo-France et 1290 stations hydro­métriques). ensuite régionalisée fournir base quantiles débits crues.L'évaluation résultats...

Synovitis of the navicular bursa is common in performance horses. The objective this study was to describe an ultrasound-guided technique inject a distended and evaluate its feasibility for use by clinician not trained technique. Twenty distal limbs horses various breeds sizes were used. To produce synovial distension, each limb injected with contrast medium using lateral approach radiography performed confirm that distending bursa. digit positioned interphalangeal joint hyperextension. A...

Abstract The latest version of the atmospheric general circulation model ARPEGE‐Climat was used to perform 5‐member ensemble simulations for both present and RCP8.5 scenario climates (mid‐21st century). rotated/stretched configuration enables a local horizontal resolution less than 15 km over tropical North Atlantic basin. Moreover, tracking algorithm extract cyclones (TCs) simulated by model. Through an Eulerian approach, this paper focuses on relationships between TCs rainfall three French...

Markov chain Monte Carlo (MCMC) methods together with hidden models are extensively used in the Bayesian inference for many scientific fields like environment and ecology. Through simulated examples we show that speed of convergence these can be very low. In order to improve properties, propose a method make parallel chains interact. We apply this biomass evolution model fisheries. Les méthodes de par chaînes couplées à des modèles cachés sont utilisées dans nombreux domaines,...

Abstract. Since the last decade, copulas have become more and widespread in construction of hydrological models. Unlike multivariate statistics which are traditionally used, this tool enables scientists to model different dependence structures without drawbacks. The authors propose apply improve performance an existing model. hourly rainfall stochastic SHYPRE is based on simulation descriptive variables. It generates long series estimation distribution quantiles for climates. paper focuses...

SHYREG method is a regionalized for rainfall and flood frequency analysis (FFA). It based on processes simulation. couples an hourly generator with rainfall-runoff model, simplified enough to be regionalized. The has been calibrated using all hydro meteorological data available at the national level. In France, that represents about 2800 raingauges of French Weather Service network 1800 stations hydrometric National Bank network. Then, provide flow quantiles database. An evaluation was...

La survie d'Escherichia coli, Straphylococcus aureus, Streptococcus faecalis a ete etudiee dans le peloide de Barbotan en fonction du temps et pH. Dans les conditions d'acidite habituellement rencontrees ce (soit pH 4 5,3) Escherichia coli disparait entre 8 15 jours ; Staphylococcus aureus 20 jours. Plus est acide, plus disparition rapide.
