Despite the air-quality monitoring networks run by approved organizations, large numbers of areas in France suffer from a lack of information about air pollution levels. Pollutant modeling enables such information gaps to be filled, albeit with certain limits. The approach used in this article to model average ozone concentrations in the city...

– Malgré les réseaux de mesures gérés par les associations agréées à la surveillance de la qualité de l'air (AASQA) en France, de nombreux espaces souffrent d'un manque d'information sur les niveaux de pollution atmosphérique atteints. Le recours à la modélisation des polluants permet de combler, avec certaines limites, ces lacunes. La démarche...

The Roya is a 60 km-long semi-alluvial riverbed, with alpine/mountain influence upstream and Mediterranean influence downstream. It is characterized by steep and narrow gorges (mean slope: 3.2%) on long reaches, and a local wandering pattern when the narrow valley floodplain allows it (mean active width: 40 m). Sediment load on the catchment...

The synoptic configurations of the particles pollution in Nice. During the first half of the year 2011 50 campaigns of itinerant measures of particles were led by bicycle in the city of Nice on the same route at the beginning of the morning. The averages calculated during every measure and for every size of particles (TSP, PM10, PM2.5 and PM1)...

Le projet CASSANDRE a pour but d'anticiper l'évolution de la végétation dans les Alpes-Maritimes afin d'identifier les zones naturelles à protéger d'ici 2100. La première étape consiste à régionaliser les sorties du modèle climatique ARPEGE-Climat du CNRM afin de renseigner localement l'évolution attendue des températures minimales et maximales...

Downscaling at fine spatial resolution of the current and future temperatures using statistical modeling of ALADIN-Climat outputs in the Alpes-Maritimes (France) The objective of this work consists in regionalizing the outputs of the model ALADIN-Climat of the CNRM to locally evaluate the minimal and maximal temperatures trends at the middle...

The combustion of vegetation during forest fires can lead to the condensation of hydrophobic compounds on mineral matter near the soil surface. The resulting water repellent layer then inhibits water infiltration by altering soil hydraulic conductivity and the water content–soil matric suction relationship. This situation resembles that of a...

Forest fire frequency in Mediterranean countries is expected to increase with land cover and climate changes as temperatures rise and rainfall patterns are altered. Although the cause of many Mediterra-nean fires remains poorly defined, most fires are of anthropogenic origin and are located in the wildland urban interface (WUI), so fire...

Le bassin versant de la Roya présente une partie amont située dans les Alpes-Maritimes, et un exutoire à Vintimille (Italie). Le caractère torrentiel du fleuve et l'occurrence d'intenses crues éclair, typiques du régime méditerranéen, en font un système fluvial particulièrement actif et complexe du point de vue hydromorphologique. L'étude...

The exceptional rainfall on Oct. 2nd, 2020 on the Maritime Alps and on the Liguria regions have considerably modified the bed morphology of several rivers in the area. Far beyond the rather localized damages observed on the Tinée or on the Fora di Taggia rivers, the Roya and the Vésubie rivers endured exceptional active width widening (see...

Fieldtrip of the Hydrosystems' Commission of the CNFG (French National Committee of Geography), July 2023. Fieldtrip organized by Margot Chapuis (Université Côte d'Azur, UMR 7300 ESPACE) thanks to the help of the Hydrosystems' Commission supervisors: Anaëlle Vayssière and Ludovic Drapier.

On the 3rd of October 2015, an outstanding hydrometeorological event hit the Mediterranean coast in the Alpes-Maritimes region in south-eastern France. Despite this rainstorm event was very short in time (approximatively 2 hours of intense rainfall), it caused a large rainfall accumulation reaching up to 180 mm. Intense flash floods were...
