Distributional shape triangles with some applications in sedimentology,bolic shape triangle. There are close analogies between the hyperbolic distributions, the generalized logistic distributions and the beta distributions, which make it possible also to define a logistic or a beta shape triangle..Using a population concept of sediment samples it is shown that both the

Assessment of aerodynamic roughness via airborne radar observations,topography on various natural surfaces and to understand the underlying physical causes for the relationship. This relationship will form the basis for developing a predictive equation to derive aerodynamic roughness (z.) from radar backscatter characteristics. Preliminary studies support the existe

The threshold friction velocities and soil flux rates of selected soils in south-west New South Wal(bare uncultivated and bare cultivated) in western New South Wales. The erodibility has been characterised by the soil flux function .(..), where.is the streamwise soil flux (measured with a modified Bagnold soil trap) and .. the friction velocity (obtained by fitting the logarithmic wind profile la

Wind degradation on the sandy soils of the Sahel of Mali and Niger and its part in desertification,ussed in this paper: in Niger west and east of the river Niger bend from N’Guigmi to Niamey and in Mali leeward of the Niger’s inland delta. The aim is 1) to describe the morphometric data of the sand accumulation, 2) to understand the actual aeolian removal of particles, 3) to analyse the effects o

Coastal erosion and aeolian sand transport on the Aquitaine coast, France,nes: parabolic dunes, barchans, round dunes and the foredune. All the dunes were constructed by westerly winds, blowing off the sea. Dating of these dunes is based on paleosols of the Great Dune of Pilat, the highest dune in Europe. The base of this dune is dated at about 3500 years B.P., but most o

Controls on aeolian sand sheet formation exemplified by the Lower Triassic of Helgoland,eds of aeolian sand sheet origin. The aeolian deposits formed during lake low-stands, and sand sheet formation was caused by a restricted sand supply perhaps in combination with frequent wind changes and high-speed wind events. With time aeolian sedimentation was progressively influenced by brief fl
