Groundwater Levels 2002
For the calculation of the groundwater isolines of the main aquifer, the irregularly distributed groundwater measurement data (base points) were transformed into an equidistant grid with the aid of a program for the calculation and graphic representation of surfaces (Surfers 7.0, by Golden Software). This was accomplished by interpolation according to the Kriging method. The 400-meter grid size produced a network of 14,241 nodes. The groundwater isolines were represented on the basis of this grid, after smoothing.
