How it was checked
- Reference
- The validated 50 m rerun, compared with Deltares’ D-Flow FM elsewhere; Q = 10,165 m³/s
- Caveat
- 50 m cells don’t resolve the groynes, and the bathymetry predates the Spiegelwaal side channel.

The Waal at Nijmegen
Abstract
7,000 particles carried by the steady flow of the river Waal at high discharge, over aerial imagery. The main channel runs fastest past Nijmegen; slower sheets of water cross the flooded floodplains inside the meanders. One second of video is ten minutes of river time.
