Abstract The Cévennes–Vivarais Mediterranean Hydrometeorological Observatory (OHM-CV) is a research initiative aimed at improving the understanding and modeling of intense rain events that frequently result in devastating flash floods southern France. A primary objective to bring together skills meteorologists hydrologists, modelers instrumentalists, researchers practitioners, cope with these rather unpredictable events. In line previously published flash-flood monographs, present paper aims...
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 This study examines the simulation of three torrential rain events observed on 13–14 October 1995 (the Cévennes case), 12–13 November 1999 Aude case) and 8–9 September 2002 Gard over southeastern part France using Meso‐NH non‐hydrostatic mesoscale numerical model. These cases were associated with extreme Heavy Precipitation Events (HPEs) significant precipitation amounts exceeding 500 mm in less than 24 hours. Several sets experiments performed 10 km 2.5 horizontal resolutions. In I...
Abstract This paper investigates the circumstances of 1,075 fatalities from flash flooding recorded 1996 to 2014 across United States. study provides insights into situations fatality events as determined by victims’ profile and activity spatiotemporal context flooding. A reclassification individual circumstance (i.e., location and/or activity) is performed explore statistically timing, duration, flood event age gender victims. In agreement with other studies, more than 60% reported were...
Abstract. The anticipated increase in solar energy production West Africa requires high-quality irradiance estimates, which are affected by meteorological conditions and particular the presence of desert dust aerosols. This study examines impact incorporating into surface temperature estimations. research focuses on a case event March 2021, is characteristic dry season Africa. Significant aerosol emissions at Bodélé Depression associated with Harmattan flow that transports plume westwards....
Abstract This paper describes and illustrates a methodology to conduct postflood investigations based on interdisciplinary collaboration between social physical scientists. The method, designed explore the link crisis behavioral response hydrometeorological dynamics, aims at understanding spatial temporal capacities constraints human behaviors in fast-evolving conditions. It builds methods coming from both geosciences transportations studies complement existing field investigation used by...
Abstract. This paper presents a coupled observation and modelling strategy aiming at improving the understanding of processes triggering flash floods. is illustrated for Mediterranean area using two French catchments (Gard Ardèche) larger than 2000 km2. The approach based on monitoring nested spatial scales: (1) hillslope scale, where influencing runoff generation its concentration can be tackled; (2) small to medium catchment scale (1–100 km2), impact network structure variability rainfall,...
Abstract This article focuses on conceptual and methodological developments allowing the integration of physical social dynamics leading to model forecasts circumstance‐specific human losses during a flash flood. To reach this objective, random forest classifier is applied assess likelihood fatality occurrence for given circumstance as function representative indicators. Here, vehicle‐related chosen literature indicates that most fatalities from flooding fall in category. A database flood...
Abstract The development of renewable electricity in Africa could be massive coming decades, as a response to the rapid rising demand while complying with Paris Agreements. This study shows that high-resolution climate experiments CORDEX-AFRICA, annual mean solar potential is expected decrease on average by 4% over most continent end century, reaching up 6% Horn Africa, direct result radiation and increase air surface temperature. These projections are associated large uncertainties,...
Abstract Many solar photovoltaic (PV) energy projects are currently being planned and/or developed in West Africa to sustainably bridge the increasing gap between electricity demand and supply. However, climate change will likely affect power generation atmospheric factors that control it. For first time, state-of-the-art CMIP models (CMIP6) used investigate potential future evolution of its main drivers Africa. A multi-model analyses carried out revealed a decrease PV throughout 21st...
The estimation of catchment-scale soil properties, such as water storage capacity and hydraulic conductivity, is primary interest for the implementation distributed hydrological models at regional scale. This generally performed on basis information provided by databases. However, databases are often established agronomic uses do not document deep-weathered rock horizons (i.e. pedologic type C deeper), which can play a major role in transfer storages. Here, we define Drainable Storage...
Flash floods are listed among the deadliest and costliest weather-driven hazard worldwide. Yet, only a few systems to predict flash run operationally in Europe. Recently, European Precipitation Index based on Climatology (EPIC) was developed then set up for daily flood early warning an area covering most of continent. EPIC is purely rainfall-driven indicator prediction statistical threshold exceedence upstream precipitation provide 5 days advance. Its main assumption that directly solely...
Abstract This study aims to understand and document the occurrence variability of cloud cover types in West Africa (WA). Investigations are carried out with a 10‐year hourly record two data products: CERES passive satellite observations ERA5 reanalysis. The seasonal evolutions high (HCC), middle (MCC), low (LCC) total (TCC) examined. Both products agree on spatial cover, although presents lower values fraction than which is partly attributed inability sensor detect optically thin clouds...
Abstract. In Mediterranean Europe, flash flooding is one of the most devastating hazards in terms human life loss and infrastructures. Over last two decades, floods brought losses a billion Euros damage France alone. One problems that warning times are very short, leaving typically only few hours for civil protection services to act. This study investigates if operationally available shortrange numerical weather forecasts together with rainfall-runoff model can be used as early indication...
Abstract Innovative coupling between the soil–vegetation–atmosphere transfer (SVAT) model Interactions Soil, Biosphere, and Atmosphere (ISBA) hydrological TOPMODEL has been specifically designed for flash-flood forecasting in Mediterranean area. The coupled described this study combines advantages of two types model: accurate representation water energy soil atmosphere within SVAT column an explicit lateral over catchment unit. Another advantage is that number parameters to be calibrated...
