Fig. 3. Peak discharges (m³/s) and their return time of the river Rhine in the Netherlands at gauging station Lobith. Werklijn 15,000 and 16,000 stand for the design discharges 15,000 and 16,000 m³/s respectively that occur 1/1250 yr under different extrapolations. The upper and second highest lines represent design discharges under two different climate change scenarios (Botzen and van den Bergh 2006).
