Wasser und Umwelt - Reference date measurements


Reference date measurements are needed to capture groundwater contour maps, temperature distributions or the distribution of pollutants in the groundwater.



The groundwater gradient and flow directions can be determined from the groundwater contour lines. The amount of subterranean groundwater can then be estimated from the groundwater gradient and flow direction. Particularly when monitoring groundwater contamination, it must be determined where a pollutant originates and what its fate is. Knowledge of the groundwater surface is also important for the delineation of catchment areas, for the establishment of drinking water protection areas, for the assessment of water exchange with surface waters, and for the assessment of size and extent of (deeper) aquifers and permeability.
