Figure 2From: Mapping the low enthalpy geothermal potential of shallow Quaternary aquifers in FinlandMethod for calculating the estimated groundwater flux. An aquifer (area X) is partly under urban or industrial use (shaded grey, area Y). The groundwater flux from area Y differs from the entire aquifer's (X) flux. The estimated flux of area Y is calculated by multiplying the proportional land use by the aquifer's recharge.Back to article page
