Overview
- The city will run a 1:5 “baby wave” model starting in the week of November 17 to test measures for a surfable flow.
- Engineers plan to reintroduce coarse gravel to the riverbed to recreate pre-cleaning sediment conditions under Prof. Robert Meier‑Staude’s lead.
- A coordination meeting brought together the Baureferat, climate and water authorities, university specialists, and the local surf community to set the next steps.
- Any structural work in the channel, including gravel deposition, requires a formal water-rights permit before implementation.
- Earlier adjustments to upstream and downstream parameters failed, and an unauthorized ramp briefly produced a wave that officials labeled dangerous and prohibited.
