Figure 3 : (Top) Examples of different behavior of the air-bubble screen regarding the air and water discharges: (a) Qw=0.1 m3/s and Qa=2.25 10-3 m3/s, (b) Qw=0.15 m3/s and Qa=2.25 10-3 m3/s, (c) Qw=0.2 m3/s and Qa = 3 10-3 m3/s, (d) Qw=0.18 m3/s and Qa=1.7 10-3 m3/s. (Bottom) Schemes of the two different types of flow. Dominant effect of the bubble screen (Sketch 1), Dominant effect of the base flow (Sketch 2).
