From memory I believe the "Ruimte voor de rivieren" project was designed for peak discharges of around 15k m3/s, but could very well be wrong there. Normal discharge is much much lower. Just wanted to see if the extreme scenario is remotely feasible (which I would say it is, though it's pretty far out). But if there is enough buffer capacity then of course you only have to dimension the pumps for longer term average high discharge, and not peak discharge. Edit: Just found this: https://edepot.wur.nl/84989 https://edepot.wur.nl/84989 1/1250 year Rhine discharge at Lobith is found to be and as higher discharges will cause major flooding upstream instead of reaching Lobith directly this should be about the max to expect. Such a peak discharge would be part of a high water period with discharges up to 15 consecutive days of >10.000m3/s, so you would need a pretty big buffer.
