If you have a river, a dam, or a question about what moved through it.
The most useful next step for Thalweg is a second river — so if you hold sonar data, a monitoring site, or an obligation to produce a count, that is a conversation worth having.
Particularly interested in
- Rivers with a monitoring obligation and no continuous method.
- Existing split-beam or imaging-sonar archives nobody has had time to read.
- Restoration projects that need a measured before and after.
- Agency, tribal and consultancy programmes running fish-passage work.
