RESULTS OF TRITIUM ACTIVITY MODELLING IN A BUNTER SANDSTONE AQUIFER

摘要

Water and tritium movement in unsaturated and saturated zones is complicated, especially in areas with inhomogeneous conditions of geology, morphologyand anthropogenic utilization. A lot of transport and storage processes in the atmosphere, pedosphere and geosphere have to be taken into consideration.The modelling of water and tritium balance in the unsaturated soil zone, especially when the aeration zone is thick and inhomogeneous, should consider infiltration, percolation, discharge and groundwater recharge. This poster shows a method of modelling tritium distribution in an unsaturated zone, tritium input into ground-water and tritium transport in groundwater by means of a coupled system aeration/ groundwater model (see Fig. 1), developed at Freiberg University of Mining and Technology.
