Modelling Of Unsaturated Flow With Nitrogen And
Phosphate Transport
Author(s)

Abstract
The irrigation or the artificial recharge of aquifers with treated waste water may
pollute the aquifer with chemical compounds or organic matter. During the
infiltration throughout the unsaturated zone several processes can occur. The
pollutants can react with each other, with the solid phase, or with the gas phase
of the unsaturated zone. To model such problems, the finite element method is
applied to the equations of flow and convection-dispersion transport of several
species in the unsaturated soil. To improve the performance of the model, a study
has been conducted to find out the numerical schemes, for time discretization
and non linear system resolution, that gives the best results. The mo
