Sažetak
Groundwater age is an important water property used as an indicator of ground water quality. Known problem of insufficient data and measurement in underground has been mitigated by using direct simulation of groundwater age. This paper has been motivated by the work of Daniel J. Goode, defining rather different approach. Numerical model has been developed using Lagrangian approach and random walk particle tracking method, where groundwater age is calculated as summed up traveling time of certain particles. Methods basic input is flow calculation ; hence an upgrade has been done to existing software solution in order to get groundwater age simulation. Synthetic examples have been simulated for homogeneous, layered and for low and medium heterogeneous aquifer systems. A stochastic analysis of heterogeneous aquifer has been done using a Monte Carlo simulation method. The results are given as groundwater age fields. An application of such approach lays in possible estimation of an expected groundwater age at certain location of water intake. Therefore, the calculated probability assumptions may be used as a decision support tool in cases of groundwater pollution, estimation of the level of aquifer’s auto purification, or in events where applying certain level of water treatment prior to usage is needed.
