The external area-to-volume ratio of the ammonite shell has been held to be related to morphology but never evaluated quantitatively. A dimensionless ratio, the Vogel number, was computed for large samples of Devonian to ...

The influence of sediments in the heat budget of water bodies has been reported to be determinant in shallow lakes and wetlands, whereas it is usually neglected in larger water bodies. In this article, we address the ...

In this work, we treat theoretically the hydrodynamic propagation of water waves propagating on an inclined face. We show a linear dimensionless model to predict the motion of the long ocean waves over the selected ...

This article discusses the results of an experimental study of a spill of mineral particles in gravel-bed rivers due to mining accidents. The purpose of this research is to characterize the dynamics of the fine mining ...
