Hydrology- isohypsen 1st aquifer package 1990-1996
Description
The file contains the isohypse 1st aquifer package (average). The data are derived from the average highest groundwater level (GHG), the mean spring groundwater level (GVG) and the average lowest groundwater level (GLG) situation 2003. The data have been corrected for mockwater levels and clay bulkheads. An isohypse or elevation line is a line on a map that connects points with equal altitude above sea level. An aquifer is a bottom layer that penetrates water and is bounded at the top and bottom by an impermeable layer or by a free water level.
