GTK50dig Geothermal drainage card 1:50,000

Project-related map, coupled to the ongoing development of the HyK 50. The map was prepared by a geothermal reassessment of hydrogeological bodies of the HyK50 basic map and the groundwater fluid level information level of the map of the protection function of groundwater cover from the special hydrogeological mapping 1:50000. The geothermal calculation is carried out by assigning the rock parameter thermal conductivity to the individual hydrogeological bodies and subsequent calculation of the specific withdrawal rate (in watts per metre) according to empirical formulas. The map serves as an estimate and is applicable to geothermal probe projects of less than 30 kW heating capacity and does not replace concrete planning for a geothermal project. The result is tuft-dependent grids for 1800 annual hours of operation (if only heating) and 2400 (heating + hot water heating) annual operating hours of a heat pump. The grid cells (50 m x 50 m) contain the averaged withdrawal power values in W/m (Watt per meter) in the field (VALUE) for each depth interval (40 m, 70 m, 100 m, 130 m). Grids for 1800 and 2400 hours per year as mosaics for the specified leaf cuts (finished sheets): g1800h_40m (for 40 m depth) g1800h_70m (for 70 m depth) g1800h_100m (for 100 m depth) g1800h_130m (for 130 m depth) g2400h_40m (for 40 m depth) g2400h_70m (for 70 m depth) g2400h_100m (for 100 m depth) g2400h_130m (for 130 m depth) For these grids for 1800 and 2400 hours and the associated drilling depths 40 m, there are 70 m, 100 m, 130 m legends (*.lyr) files that output the average withdrawal power in watts per metre in grouped color gradations.
