Abstract
We propose here a project to study the complex phenomenon of groundwater
pollution with nitrogen compounds. It is an attempt to answer the following basic
questions: having found the quantity of rain or irrigation, and the quantity of
fertilizer, how much will these damage the layer of drinkable water? Which is
the best solution to minimize the damage? Our proposal is based on our earlier
work, which treated the fluid flow through the first layer of unsaturated soil. Our
main goal is to extend the model to include what happens in soil lower levels and
how the influence of groundwater hydrodynamics can be taken into account. The
nitrogen compound transformations take a key role in our study, which is
multidisciplinary (fluid mechanics, chemistry, agriculture studies engineering).
The soil pollution study implies the computation of the pollutant concentration
through the soil profile. The mathematical models achieve the integration of
equations describing the water movement and the pollutant concentrations. We
have calibrated the hydraulic model using experimental data.
Keywords: groundwater, pollution, unsaturated soil, nitrogen, nitrate, pollutant
concentration, pressure head, mathematical model, coupled model.
1 Introduction
Groundwater systems are in continuous dynamic interaction at local,
intermediate, and regional scales with the surface water systems through the
