✦ Synopsis

This paper describes a new numerical method used within the SUBIEF software to compute the transport of diluted or suspended tracers in a two-dimensional depth-averaged free surface ¯ow for domains where the ¯ood extent varies with time. The transport equations and the numerical choices for time and space discretization in ®nite elements are described prior to developing two alternative formulations for dealing with partially dry elements. Finally, we depict two typical applications of the software: the simulation of sedimentation in the intake of a power plant qualitatively validated by comparing numerical results obtained from SUBIEF with those from a physical model, and a simulation of heavy metal adsorption/desorption on to sediment particles in a ¯uvial ¯ow which are subsequently deposited and resuspended.

## Abstract The transport coefficients of macromolecular solutes are normally extrapolated to “infinite dilution” to remove the effects of concentration‐dependence terms, for which no satisfactory general treatment has been available. It is shown that a simple general treatment for the concentratio
