Space-Time-Modelling of Ascending Salty Sewage Water in the Werra-Potash District (Middle Germany)

Since 1925 salty sewage water of the potash-industry (Werra-region, Middle Germany) has been deposited in the geological setup. A quasi-closed system was assumed. It was found out that a part of the salt water ascend to the surface again. Time series-analysis allow a precise analysis of the outcoming salt water. To separate trend and periodical shares the time series were filtered numerically. The Fourier-transformation allows an investigation of the periodic shares. After the evaluation of the data it seems possible that two bodies of water united into one single body of waste water. The spreading of salty water in the underground was modelled by the concept of cellular machines.
