Hydraulic conductivity in rock
Description
The data set ‘Hydraulic conductivity in rock’ includes calculated hydraulic conductivity (K) in the rock closest to rock drilled wells from the Brunnsarkivet and an interpolation of these values. In addition to uncertainty in the input data, a number of assumptions are included in the calculations, which entails some uncertainty in the final result. Uncertainty in calculated hydraulic conductivity can be significant for an individual well. This means that the uncertainty in interpolated hydraulic conductivity in areas with few wells is high. The product is primarily aimed at specialists in hydrogeology. It can be used as a basis for hydrogeological investigations where groundwater in rock is an important factor to take into account, such as individual water supply, tunnels, quarries and mines. Due to the uncertainties and limitations in the documentation and the purpose and requirements of the investigation, additional investigations may be required. But even in these cases, the dataset can be valuable in initial investigations. The interpolation includes a nationwide calculation and the result is presented in the unit m/s (meters per second) in a grid with cell size of 100x100 m. Estimated hydraulic conductivity in rock includes the subset of rock drilled wells in the Brunnsarkivet that SGU considers it reasonable to use for this purpose.
