Groundwater: Thickness of unsaturated soil zone

Groundwater: Thickness of unsaturated soil zone The geometric data have been developed in the framework of the project “Aquiferral water level of the main aquifer Brandenburg” in 2013. The thickness of the unsaturated soil zone is defined as a perpendicular distance between the terrain surface and the groundwater pressure area. For regionalisation, approximately 14,100 holes and a Kriging interpolation process were used. The dissolution took place in the grid of 10x10 m. Calculated areas of < 25.000 m² have entered the enveloping area. Lakes with an area < 25.000 m² have not been taken into account and have also been dissolved into the surrounding area. Open pits (as of 2011) were cut out. As a result of the processing, over 37,700 individual surfaces in 13 classes of thickness could be documented. Of these, 31 % of the land surface has an unsaturated soil zone of < 2 m and 50 % of < 5 m thickness.地下水：非饱和土层厚度 本几何数据于2013年依托“勃兰登堡主含水层水位（Aquiferral water level of the main aquifer Brandenburg）”项目框架研制完成。 非饱和土层厚度定义为地表与地下水承压面之间的垂直距离。为开展区域化处理，本次数据集采用了约14100个钻孔数据及克里金（Kriging）插值方法，插值计算基于10米×10米的网格尺度完成。面积小于25000平方米的计算区域将被纳入包围范围；面积小于25000平方米的湖泊未纳入统计范畴，且被并入周边区域。截至2011年的露天矿坑已被剔除出数据集。 经上述处理，共可记录13个厚度等级下的超37700个独立地表单元。其中，31%的陆地区域非饱和土层厚度小于2米，50%的区域非饱和土层厚度小于5米。
