110. Flux et crues singulières d'un petit cours d'eau andin ou les effets pervers de l'urbanisation

Abstract

Sur un petit bassin de haute montagne (4000 m), situé dans les Andes à proximité de La Paz, la canalisation des "rios" en vue de gagner des terrains urbanisables, n'a guère modifié, en termes de bilan annuel, les régimes hydrologiques mais a eu des conséquences inattendues sur leur comportement en crue. Au delà d'un certain débit, bien inférieur au débit maximum décennal, apparaissent des vagues, parfois plus hautes que le canal, qui déferlent à près de 10 m/s, endommageant sur leur passage ponts et parois de l'ouvrage, et provoquant d'importants débordements en zone urbaine. Plus en amont, dans le lit naturel, l'écoulement demeure stable. Plusieurs hypothèses sont avancées pour expliquer ce phénomène. (Résumé d'auteur)

125. Identifying the probabilistic structure of drained areas as a function of hypsometry in river networks.

Abstract

Classical morphological descriptors of river networks have been developed in 2D planar system. The third z-dimension (elevation), however, is necessary to model landscape evolution, particularly in a mountainous region when taking into account transport processes such as in glaciology and erosion. This paper aims at analyzing 3D morphometric properties of channel networks on the basis of probabilistic relationships relating the drained area and the elevation. The methodology is an extension of the fundamental planar power-law description proposed by Rodriguez-Iturbe et al. () representing the probability that the drained area A is higher than a threshold area a, P[A > a] ~ a− β, where β is constant and represents an invariant property of natural river networks. A new scaling factor taking into account hypsometry is introduced in the previous power-law relationship, as [ABSTRACT FROM AUTHOR]

148. Optimization of the geopotential heights information used in a rainfall-based weather patterns classification over Austria.

Abstract

Classifications of atmospheric circulation patterns are useful tools to improve the description of the climate of a given region and the analysis of meteorological situations. In particular, weather pattern (WP) classifications could be used to improve the description of spatial heavy rainfall. Here, a bottom-up approach, previously used to build WP classification in France, is applied for the definition of a WP classification useful for the description of Austrian heavy rainfall. The optimal spatial extent and the optimal position of the geopotential fields to be taken into account for a WP classification is studied. The proposed WP classification is shown to be coherent with the general knowledge on synoptic situations responsible for heavy rainfall over Austria. Moreover, the classification has good performances in terms of heavy rainfall spatial description compared to 152 COST 733 classifications defined in the same region. In particular, we show that the choice of spatial extent of the geopotential fields, their position and their characteristics is relevant for capturing physical information on synoptic situations responsible for heavy rainfall and that it can improve WP classification performances.
