Aare River

In autumn 2006, a maximum PFBS concentration of 2,900 ng/L was measured in the upper Rhine within a period of about two weeks [58]. This high level was a consequence of a contamination in the Aare River in Switzerland before the... [Pg.81]

Fig. 2 There are two major hydrological modifications due to hydropower operation on River Aare levelling of seasonal flow (upper panel) and hydro-peaking (lower panel). Upper panel Seasonal flow (at Brienzwiler) before hydropower operation (1905-1928) and with a storage capacity of 200 Mio m (1980-2003). Note the shift from summer to winter. Lower panel Daily hydro-peaking fluctuations due to electricity production. Note low flow on weekends.

Fig. 4 (a, b) Particle transport in 1904/5 ([18]) before construction of the reservoirs in the Upper Rhone catchment, compared to recent (www.hydrodaten.admin.ch) particle transport. The unique, century-old dataset confirms the massive increase during winter (a) and massive reduction during summer (b). (c) Comparison of particle transport in two catchments with similar properties (see text), but distinctly different levels of damming. In the River Lutschine (no dams), the transport is concentrated to July/August and negligible in winter, whereas in the River Aare (200 Mio storage) the transport is reduced and significantly levelled over the season with a shift from summer to winter.

Measurements in an aquifer at the River Aare in Switzerland by Schwarzenbach et al. (1983) show a time lag of about 4 months between the concentration in the river and in a well situated about 13 m from the river. The corresponding amplitude ratio is about 0.8. In the same aquifer, the annual temperature variation shows a shift of 1 month from the river to the observation well. This demonstrates the more conservative (or less sorbing ) nature of water temperature versus PCE. [Pg.1176]
