Summary
A model for the simulation of leaching of non-adsorbed anions is described. The model can also be used to study the degree of salinization by evaporation.
The accent is laid on usefulness under practical conditions. In view of this it has been assumed that transport of ions is only caused by mass flow and hydrodynamic dispersion.
Data about soil and profile, initial water and salt conditions and ground-water level must be known. Given a precipitation and evaporation distribution the model can compute the leaching or accumulation of nitrate or chloride during a long period ofe.g. 125 days.
The results of a number of computations are compared with theoretical expectations and actual measurements. There is a passably good agreement.
