摘要

Tracer investigation and numerical modelling of the movement of water and solids in the unsaturated and saturated zone of an aquifer enables to quantitatively predict the impact of different measures on the whole system. However, setting up a model and determining model parameters still calls for substantial research efforts. The results of tracing experiments in the unsaturated zone of a quaternary gravel fill were used to prove the measuring and sampling devices on their ability to detect transient transport phenomena of water and solutes, to illustrate the differences between hydraulic reaction of water content on infiltration events and the velocity of solute movement in the unsaturated zone, to estimate hydraulic parameters of soil horizons as a basis for the calibration of solute transport models in the unsaturated zone, to quantify different flow components using advection-dispersion transport modelling and to correct measured flow data of field lysimeters.
