LGRB-BW Potentially reduced protective function due to karting hazard

In areas with risk of karstisation, the protective function of groundwater cover may be significantly lower due to karst structures than determined by the Hölting method used. The present data set does not distinguish which rocks (sulfate and/or carbonate rocks) may have possible karst phenomena. In areas without a geological 3D model, roughly areas where karstisation is possible are additionally endured.在存在喀斯特作用（karstisation）风险的区域，受喀斯特构造的影响，地下水覆盖层（groundwater cover）的防护功能可能显著低于采用赫尔廷法（Hölting method）测算的结果。本数据集未区分哪些岩石（硫酸盐岩和/或碳酸盐岩）可能存在喀斯特现象。在缺乏地质三维模型（geological 3D model）的区域，即大致存在喀斯特作用可能性的区域，此类区域会被额外纳入本数据集。
