Total sediment transport was estimated as the summation of the transport rate of 12 sediment size fractions which were computed by an algorithm composed of three different transport relations An effective diameter for critical flow strength is used in the algorithm to account for the effect ofthe sediient mixture on the initiation of motion of each size fraction. Tests with laboratory and field...

After describing the main characteristics of grain-size curves, we recall previous results about Principal Components Analysis of absolutely continuous measures, in connection with grain-size curves analysis. This method simultaneously takes into account a chosen reference probability (r.p.) μ (associated with a Radon-Nikodym derivation operator), and the imposed sampling mesh Tp. The point is ...

We analysed the long-term variations in grain-size distribution in sediments from Gåsfjärden, a fjordlike inlet in the southwestern Baltic Sea, and explored potential drivers of the recorded changes in the sediment grain-size data. Over the last 5.4 thousand years (ky) in the study region, the relative sea level decreased 17 m, which was caused by isostatic land uplift. As a consequence, Gåsfjä...

[1] In this, the first of a pair of papers which address the simulation and automated measurement of well-sorted natural granular material, a method is presented for simulation of two-phase (solid, void) assemblages of discrete non-cohesive particles. The purpose is to have a flexible, yet computationally and theoretically simple, suite of tools with well constrained and well known statistical ...
