Behaviour of Tritium and Tritiogenic Helium in Freshwater Lens Groundwater Systems: Insights from Langeoog Island, Germany

Figure 10

Contour plots of the simulated ³H concentration activities (shaded colours) and Cl concentrations (white lines) at the end of the simulation period (31 December 2013). The five white lines represent Cl concentrations equal to 2.5%, 16%, 50%, 84%, and 97.5% of the seawater chloride concentration (17 g/L). Results are shown for simulations (a) A4, (b) A5, (c) A6, (e) A7, (f) A8, and (g) A9. The location of the clay layer is indicated by the hatched white rectangle. The open red rectangle in (d)–(f) encloses the cells with groundwater abstraction, and the dashed white line indicates the projected location of observation well 17.
