The key role of surface tension in the transport and quantification of plastic pollution in rivers

Current riverine plastic monitoring best practices mainly consider surface observations, thus neglecting the underlying distribution of plastics in the water column. Bias on plastic budgets estimations hinders advances on modelling and prediction of plastics fate. Here, we experimentally disclose the structure of plastics transport in surface...

Introduction to a depth-integrated model for suspended transport (Galappatti, 1983)

It is the aim of this note to give a simple introduction to the method as used by Galappatti (1983) to derive a depth-integrated model for suspended transport. Contrary to other depth-integrated models (see e.g. Latteux and Teisson, 1985) this model is directly based on the 2D convection-diffusion equation (see e.g. de Vries, 1981) including the...

A depth integrated model for suspended transport

A new depth averaged model for suspended sediment transport in open channels has been developed based on an asymptotic solution to the two dimensional convection-diffusion equation in the vertical plane. The solution for the depth averaged concentration is derived from the bed boundary condition and the computation of transport rate and...
