“…The range of suspended sediment concentration in the Eshtemoa basin covers similar orders of magnitude of other semi-arid and arid-zone drainage basins (Alexandrov et al, 2003). Distinct seasonal differences are identified and related to the prevalence of cellular, convectively enhanced storms in autumn and spring and frontal storms in winter (Alexandrov et al, 2009). In northwest Algeria Megnounif et al (2007) investigated the variability and seasonality of suspended sediment transport in the Wadi Sabdou collecting water samples during 19 flood events (1988)(1989)(1990)(1991)(1992)(1993).…”

“…Powell et al 1996). Also, it is the large volume of floods which accounts for most of the suspended sediment yield (Alexandrov et al 2009). However, it is the high discharges associated with high peak discharges, which give rise to exceptionally large fluxes of bed load (Laronne and Reid 1993).…”

Results of a comprehensive synoptic-hydrological analysis of major flood events in the Negev are presented. A low threshold for major flood data was set to be the 10-year recurrence interval of peak discharge and/or flood volume magnitude. Altogether, 75 major flood events, or 133 hydrometrically monitored floods, were extracted. These events were categorized according to synoptic oriented classes by verification of the paired databases of: (a) floods in the study area, and (b) synoptic systems over the Eastern Mediterranean. For the study area, two of the most frequent flood-generating synoptic systems are the autumn Red Sea Trough (RST), 31%, and winter cyclones, 49%. The entire RST series consists of 24 major flood events (55 floods). The synoptic definition was corroborated by analysing the specific form of flood hydrographs and the ratio of flood volume to peak discharge. Regional analysis shows increased contribution of RST events southwards from 30% to 90% with a respective decrease in the number of cyclone events. By comparing two 22-year sub-periods (1964-1985 and 1986-2007), a positive trend in the frequency and magnitudes of RST flood events is discerned. There is also an increased tendency for the occurrence of cyclone floods.Key words floods; synoptic system; Red Sea Trough (RST); climate change; Negev; Arava; Dead Sea; Mediterranean Crues dans le Néguev, Israël (1964-2007) dues à des dépressions sur la Mer RougeRésumé Nous présentons les résultats d'une analyse exhaustive synoptique/hydrologique des crues majeures dans le Néguev (1964Néguev ( -2007. Le seuil inférieur pour les crues majeures a été défini comme le débit de pointe ou le volume de la crue de récurrence 10 ans. Au total, 75 crues majeures, ou 133 crues observées hydrométriquement, ont été extraites. Ces événements ont été classifiés selon des classes synoptiques par vérification des bases de données appariées : (a) des crues dans la zone d'étude, et (b) des systèmes synoptiques sur la Méditerranée orientale. Pour la zone d'étude, deux des systèmes synoptiques générant le plus fréquemment des crues sont les dépressions sur la Mer Rouge (DMR) en automne, 31%, et les cyclones d'hiver, 49%. La série DMR complète est constituée de 24 crues majeures (55 crues). La définition synoptique a été corroborée par l'analyse de la forme spécifique des hydrogrammes de crues et le rapport entre volume et débit de pointe des crues. L'analyse régionale montre une contribution des événements DMR augmentant de 30% à 90% vers le Sud avec une diminution correspondante du nombre d'événements cycloniques. En comparant deux sous-périodes de 22 ans (1964-1985 et 1986-2007), on discerne une tendance positive dans la fréquence et la magnitude des crues DMR. Il ya aussi une tendance croissante à l'apparition de crues d'origine cyclonique.
