Core Ideas OZCAR is a network of sites studying the critical zone. covers various disciplines. will help disciplines to work together for better representation and modeling The French zone initiative, called (Observatoires de la Zone Critique–Application et Recherche or Critical Observatories–Application Research) National Research Infrastructure (RI). OZCAR‐RI instrumented sites, bringing 21 pre‐existing research observatories monitoring different compartments situated between “the rock...
Abstract Different approaches used in hydrological modelling are compared terms of the way each one takes rainfall data into account. We examine errors associated with accounting for variability, whether (distributed vs lumped models) or computing catchment rainfall, as well impact approach on representativeness parameters it uses. The database consists 1859 events, distributed 500 basins, located southeast France areas ranging from 6.2 to 2851 km2. study uses reference hydrographs computed...
Key Points A general framework for comparing frequency analysis methods Focus is on the predictive performance of Reliability uncertainty estimates assessed using a distribution
Abstract. Floods are a major natural hazard in the Mediterranean region, causing deaths and extensive damages. Recent studies have shown that intense rainfall events becoming more extreme this region but, paradoxically, without leading to an increase severity of floods. Consequently, it is important understand how flood changing explain absence trends magnitude despite increased extremes. A database 98 stations southern France with average record 50 years daily river discharge data between...
This article presents a comparison between real-time discharges calculated by flash-flood warning system and post-event flood peak estimates. The studied event occurred on 15 16 June 2010 at the Argens catchment located in south of France. Real-time warnings were provided AIGA (Adaptation d'Information Géographique pour l'Alerte en Crue) system, which is based simple distributed hydrological model run 1-km2 resolution using radar rainfall information. timing (updated every min) was compared...
A method was designed to study frequency distributions of hydrologic variables (rainfall and discharge) which combined a stochastic model for hourly rainfall with general conceptual transforming into discharge. The generates many different flood events over given simulation period evaluate risks. Simulated Hydrographs Probability Estimation (SHYPRE) based on the use observations describe phenomena statistically reproduce them. Frequency hydrological are built empirically from simulated...
The Mediterranean proliferation of Caulerpa taxifolia provides an opportunity to examine the extent which introduced species can modify biodiversity. During 1992, benthic invertebrates were sampled in Roquebrune-Cap Martin area, at depths 6 and 10 m, from a station reference station. Species richness is slightly lower m within while number specimens much reduced both depths. Similarity indices compare well between stations. , distributed tropical seas, was recorded for first time 1984, as...
Abstract. Flood frequency analysis (FFA) aims at estimating quantiles with large return periods for an extreme discharge variable. Many FFA implementations are used in operational practice France. These range from the estimation of a pre-specified distribution to continuous simulation approaches using rainfall simulator coupled rainfall–runoff model. This diversity raises questions regarding limits each implementation and calls nation-wide comparison their predictive performances. paper...
Abstract. This contribution presents a regionalization approach to estimate spatially distributed hydrologic parameters based on: (i) the SMASH (Spatially Modelling and ASsimilation for Hydrology) hydrological modeling assimilation platform (Jay-Allemand, 2020; Jay-Allemand et al., 2020) underlying French national flash flood forecasting system Vigicrues Flash (Javelle 2019); (ii) variational algorithm from (Jay-Allemand 2020), adapted high dimensional inverse problems; (iii) spatial...
Abstract The SHYPRE method is a flood risk estimation approach applicable on any point of territory. It based the coupling an hourly rainfall stochastic generator with rainfall—runoff model. As first step, carried out over whole France, regionalization model parameters (obtained from 217 reference recording raingauges) was done basis available daily information. information 2812 raingauge stations used to create maps at scale one-square-kilometre pixel; data 612 additional raingauges were...
RésuméLa méthode SHYREG est une approche développée pour la connaissance régionale de l'aléa pluvial (SHYREG pluie) et hydrologique débit) en tout point du territoire français. Elle basée sur le couplage d'un générateur stochastique pluie horaire modèle hydrologique. Cet article présente les résultats mise œuvre 1605 bassins versants répartis France métropolitaine. Sur fréquences courantes (c.à.d. périodes retour inférieures à 10 ans), restitue correctement quantiles débit crue ajustés loi...
The objective of flood frequency analysis (FFA) is to associate intensity with a probability exceedance. Many methods are currently employed for this, ranging from statistical distribution fitting simulation approaches. In many cases the site interest actually ungauged, and regionalisation scheme has be associated FFA method, leading multiplication number possible available. This paper presents results wide-range comparison families different schemes based on regression, or spatial physical...
The taxonomy and systematics of the Neotropical genus Dendropaemon Perty is revised. current study recognize 41 species organized into 12 subgenera. establishment subgenera reflecting presented phylogenetic analysis. Six are established from previously available group names: Coprophanaeoides Edmonds, 1972; Perty, 1830; Enicotarsus Laporte, 1831; Eurypodea Klages, 1906; Onthoecus Lacordaire, 1856; Paradendropaemon 1972 Tetramereia 1907. additional described as new: Glaphyropaemon n. subg.;...
Abstract. The Réal Collobrier hydrological observatory in south-eastern France, managed by Irstea since 1966, constitutes a benchmark site for regional hydro-climatology. Because of the dense network stream gauges and rain available, this provides unique opportunity to evaluate long-term hydro-meteorological Mediterranean trends. main catchment (70 km2) its sub-catchments are located Massif des Maures close coast. vegetation is composed forest mainly calcified on crystalline soils (maquis...
A probabilistic method of modeling the floodwater level in a dam reservoir is described purpose this paper to add probability dimension hydraulic loading computations. Unlike standard engineering approach, presented here incorporates two innovative aspects. First, uses hydrological (simulated hydrographs for flood estimation method) based on simulation techniques, generating multiple scenarios. Second, it can address variability at time occurrence event. The generates random set levels from...
