Resumo
The present work had as objective to develop a computational routine for the
determination of the sedimentation velocity in the drain and to verify its application through a model
of transport of sediments and to compare the results obtained with experimental data. It was used in
the routine the iterative process of Newton-Rapshon for the solution of the equations applied in the
determination of the sedimentation velocity in the drain, and on the solution of the transport of
sediments equation was applied the technique of the finite differences. Those routines were used in the
implementation of the model MTSES (Model for solute transport in the soil and in the drain). The
sedimentation velocities obtained by the developed routine were overestimated, with a medium
relative error of 0.63%, which allowed the use of the developed routine in MTSES. The MTSES model
overestimated the total of sediments transported by the drain, for all the applied precipitation
intensities in this study with variations from 15.6 to 58.3%.
