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

Figure 8

Predicted fluid flow fields at the example site Spree-Havel: (a) fluid pathways for model scenario 2; (b) fluid pathways for model scenario 3. Geographic location reference of panels (a) and (b) in Figure 7(a). North is up. Pathways were derived from the modeled nodal volumetric flux through the StreamTracer filter of ParaView [71] for the final solution time step (quasi-steady state). The color-coding represents the Darcy flux in the vertically positive (uprising in orange) or negative (infiltrating in blue) direction. Termination points of the lines correlate with either sites of recharge (light blue) or discharge (bright orange).
