Surface to Groundwater Interactions beneath the City of Berlin: Results from 3D Models

Figure 3

Elevation distribution of topography and geological top surface. Thin black lines represent surface water body outlines. (a) Topographical distribution of the model area as derived from a high-resolution digital elevation model (DEM) [37], representing the top of surface water bodies. The light blue line represents the political border of Berlin. (b) Elevation distribution of topmost geological surface (Holocene) for exemplary site Lake Tegel as derived from combining the elevation data from (a) and water depth data (Figure 4); Top Holocene represents the bottom of surface water bodies. Coordinates are in Gauß-Krüger DHDN Zone 4.
