GIS-based Subsurface Model
The GIS-based Subsurface Model was established by construction of geological surfaces using 90 intersected 2,5D cross-section data. The subsurface model is divided into five geotechnical units (clay, clayey sand, silt, sand, gravel). It covers an area of 106 km² and has a maximum depth of 22 m, a minimum depth of 0.1 m and a medium depth of 4 m below the surface
