The spatial organization and scaling properties of a number of physical variables in river basins are analyzed within the framework of the multifractal formalism using data from digital elevation maps. The analysis of nine very different basins
in the United States shows that the multifractal spectra for each of the variables are very similar across basins, revealing a common structure of organization. This structure is compared to networks generated with Scheidegger's stochastic model of river basins
The technique is described and employed in structuring the relationships between the morphometric and topologic attributes of a sample of 36 monolithologic third-order drainage basins in the Udi-Awgu cuesta, south-eastern Nigeria, and the factors
controlling their development. The canonical solution identifies three significant patterns of association between basin planimetric properties and their causative and deterministic factors. The texture of dissection is strongly associated with soil
and vegetation characteristics while the stream network size and the stream bifurcation ratio are closely related to the stage of basin development and basin relief respectively.
The change from limnic to terrestrial sedimentation is regarded as a marker of the N/Q boundary in the Carpathian basin. It is roughly synchronous with the Matuyama-Gauss paleomagnetic reversal (million years). The boundary is easy to trace
in mountains, but more difficult to define in basins where oscillations of water level took place. DLO).
The Yaracuy basin is a tectonic depression within an echelon stepover in the Bocono-Moron-El Pilar fault system. This basin is interpreted as a pull-apart basin formed by right-lateral offset along this fault system. The right-lateral offset
necessary for the formation of the basin and its present dimensions is 50 to 60 km| this figure is consistent with estimates of a total late Tertiary-Quaternary right-lateral offset of 100 to 125 km along the Bocono-Moron-El Pilar fault system, which is part
Les bassins du sud-ouest Pacifique et de Somoa sont assez mal connus. Cet article présente les résultats préliminaires d'une étude consacrée à la bathymétrie, aux caractères sédimentaires, à la structure, aux nodules de manganèse, à l'hydrologie et
à la biologie de ces deux bassins. Une carte schématique montre le profil du bassin. (P. Maquigneau).
