Wind degradation on the sandy soils of the Sahel of Mali and Niger and its part in desertification,s is increasing in the same direction. The grain size 400 µm is a threshold: the upper limit of actual, average aeolian deflation..This area, which previously had a positive sediment balance, during the last drought combined with agricultural overuse became an area of sand and dust removal with a negative sediment balance.

Distributional shape triangles with some applications in sedimentology, hyperbolic shape triangle and the beta shape triangle provide useful information on variations of grain size distributions, in cross-shore transects. This information can be related to the process-oriented erosion/deposition model developed previously in connection with the hyperbolic shape triangle.

The aeolian deposits define sedimentary cycles of various thickness, and it is suggested that the cyclicity records Early Triassic orbital climatic forcing.

Since the beach sediments consisted of well-sorted and very well-sorted fine sands, partly reworked from the dunes during the storm surge, deflation was not grain-size selective during the period of post-surge dune recovery.

On the temporal-spatial variation of sediment size distributions, proposed and investigated. The model is closely related to the logarithmic hyperbolic distribution and preserves the hyperbolic shape of log-size distributions. In order to facilitate specification of the model in applications the concept of a ‘local erosion time’ is introduced. The local erosion t
