DRASTIC parameter "A - Aquifer media" for Pilot area Tønder (Denmark)
This is the third parameter for the DRASTIC groundwater vulnerability assessment (Aller et al. 1987) applied at the HOVER WP7 pilot area Tønder (Denmark).
This geotiff is derived from the conceptual geological model of the area. The 3D geological model (Jørgensen et al., 2015) was not used for this simplified version of the A-parameter. We assess the aqifer of the Glaciotectonic complex, which is classified ad "Glacial till". The entire area takes the value 5. See HOVER D7-2 for more details and references.
