For the simulation of water movement and pollutant transport in the hydromorphic soil profile two numerical models SWATREZ and UNDYS were used. These models are based on water movement in porous materials and hydrodynamic dispersion equations. The results obtained by numerical simulation were verified by field research data from the �Hajdów� experimental station situated near Lublin (Poland). The �Hajdów� experiment combines the municipal waste treatment process with industrial plant production. Empirical verification obeyed the groundwater table level, nitrogen ion concentration in the soil water at various depths and in water outlets from the drainage system. The simulation results presented show the important role of plant roots in the use of nitrogen at �Hajdów� type stations. It indicates that the best design and management of such objects must take into account not only ground filter, but also plant growth theory. The SWATREZ model gives a quite good approximation of empirical data. It can be used for the water management process in �Hajdów� type stations. Simulation based on the UNDYS model shows that the continuation of numerical research is very necessary. |
