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

Figure 9

Model results temperature. (a) Temperature distribution at -500 m.a.s.l. for model scenario 1. (b) Temperature distribution for M1 at -3500 m.a.s.l. (c) Temperature difference between M2 and M1 at -500 m.a.s.l.; zoom-in shows temperature differences at the Lake Tegel site. (d) Temperature differences between M3 and M2 at -500 m.a.s.l.; zoom-ins: (left) River Spree and Havel site and (right) Mühlenfließ. (e) Distribution of temperature differences between the different model scenarios depicting the relative influence of rivers, lakes, and rivers + lakes combined (minimum difference of ±0.1°C). (f) Distribution of significant temperature differences over depth between the different model scenarios (chosen threshold is ±0.1°C). Coordinates are in Gauß-Krüger DHDN Zone 4.
