Le Dossier Départemental des Risques Majeurs (DDRM) est un ouvrage de sensibilisation aux risques majeurs, illustré par des cartes d'aléas schématiques. Il a pour but de recenser, de décrire, et de porter à la connaissance du public l'ensemble des risques majeurs recensés dans le département et les communes concernées, ainsi que les mesures de sauvegarde prévues pour en limiter les effets.

L'objet de la présente étude est de réaliser une cartographie des aléas et des enjeux avec une précision suffisante pour déterminer le risque incendie de forêt sur 186 communes et servir de base, le cas échéant, aux Plans de Prévention du Risque Incendie de Forêts réglementaires.

"Towards an integrated prediction of Land & Sea Responses to global change in the Mediterranean Basin" The LaSeR-Med project aims at investigating the effects of climate change and of mediterranean population growth on some major indicators of the Mediterranean Sea (primary production, carbon export, zooplankton biomass available for small pelagic fishes, pH, dissolved oxygen) using and integrated model encompassing a socio-economic model, a continental model of agro-ecosystems, and a physical ocean-atmosphere model coupled to a biogeochemical model of the ocean. Last, a model for the widespread species of jellyfish Pelagia Noctiluca (Berline et al., 2013) uses biogeochemical outputs as food forcing for the jellyfish. In this project, our first aim was to investigate the large-scale and long-term impacts of variations in river inputs on the biogeochemistry of the Mediterranean Sea over the last decades (see Pages et al., 2020a). This interdisciplinary project provided the framework for joint discussions on each of the sub-models that constitute the integrated model, namely the socio-economic model (Ami et al., in prep., Mardesic et al., in prep.) created ex nihilo by researchers from AMSE, INRA and GREQAM, the continental agro-ecosystem model LPJmL (Bondeau et al., 2007) worked on at IMBE so as to include the nitrogen and phosphorous cycles in the frame of the present project, and the ocean biogeochemical model Eco3M-Med developed at MIO (Baklouti et al., 2006; Alekseenko et al. 2014, Guyennon et al., 2015; Pagès et al., 2020a), forced by ocean physics, either using the ocean model NEMO-Med12 forced by atmosphere at IPSL (simulation NM12-FREE run with the NEMO-MED12 model and used for our hindcast simulation, see below) or a coupled ocean-atmosphere model at CNRM (physical forcing provided by CNRM-RCSM4, see below). Details on simulation NM12-free: The historical simulation used in this work is referred to as the NM12-FREE (no reanalysis no data assimilation) which started in October 1979 and ended in June 2013 (Hamon et al., 2016). It has been run with the general circulation model NEMO in its regional configuration NEMO-MED12 based on a horizontal resolution of 1/12 de degree (6.5 to 8 km cells) and a 75-level vertical resolution (of 1 m width at the surface to 135 m at the seabed). For this simulation, runoff and river inputs in the NM12 domain came from the inter-annual data of Ludwig et al. (2009) and the atmospheric forcing was based on the dynamical downscaling of the ERA-INTERIM reanalysis, i.e. ALDERA which has a 12 km spatial resolution and a 3 h temporal resolution. More details on the NM12-FREE simulation are given in Hamon et al. (2016).

Cette couche recense les Zones d’Activités Economiques (ZAE) présentes sur le département de la Charente. Initialement crée par Charente Développement, il s'agit d'un surfacique qui permet d'identifier précisément le contour de ces zones en se calant sur les données du Cadastre.

ABSTRACT : Time series of the monthly means of potential temperature, salinity and potential density recorded on the HydroChanges consecutive moorings in the Gulf of Lion (41° 59.0' N 04° 55' E) few meters above the bottom (~2320m), between 2006 and 2011. N.B.: data from 2003 to 2006 exist but moorings are yet to be recovered. Observing strategy Mooring with 1 Seacat SBE37 and usually one currentmeter. Seacat SBE37 fitted with pump and pressure sensor for accurate computation of the salinity, and mostly sent to recalibration at SeaBird after their deployment.
