Map 02.07 Depth to the Groundwater 1995 (Edition 1998)

Explanations and Imprint of the Map
  1. The depths to groundwater were calculated by a computer aided procedure from the difference between surface heights and the height of the groundwater level above sea-level.
  2. The terrain elevations were taken from the Terrain Elevations Model in the Environmental Information System (UIS). The interpolation of the statistical base (85 000 points)and the calculation into a common grid was made with the program SICAD-SCOP (GIS software)
  3. The calculations of groundwater levels are based on data taken from approximately 1,500 groundwater measuring sites. The data was collected in May 1995. They were interpolated and calculated into a common grid.
  4. The depth to groundwater for areas with a confined groundwater is defined as the distance between the lower edge of the covering mantle (or the upper edge of the groundwater aquifer) and the surface. Measurements taken from the geological drillings are used to establish values for the depth of confined groundwater areas. From the Barnim flat upland approximately 100 drillings were considered. From the Teltow flat upland nearly 40 drillings were considered. Through this process of measuring and sampling, one has a model of the upper surface of the groundwater (hydro-contour lines - lines of the same groundwater level). Interpolation of data was made with the program SICAD-SCOP (GIS software)
  5. A Difference Model was calculated using the Model of the Upper Surface of Groundwater and the Terrain Elevations Model (model of the altitude of ground about sea-level).
  6. Specially on the flat uplands can appear sandy interstratifications in the boulder marl layer, with near-surface perched groundwater which can hardly be localized, and cannot be portrayed. Portrayed is the main groundwater level (sandy layers of Saale ice-age).
  7. Because of the state of the data, the Terrain Elevations Model will show some inaccuracies. This relates on the one hand to areas in the outlying districts (forests and agricultural areas) with not enough points of elevation and on the other hand to areas that were not yet developed at the time when the measurements were taken. Because of anthropogenic landfills, some of the map showing depressions with a low depth to groundwater no longer exist.
  8. Because of the chosen scale and the used methodology the map should portay an overview, she cannot substitute investigations with smaller scales.
