Confluence
Where two rivers meet and the basin grows a name.
The moment a basin gets a name
A confluence is a handshake between two drainage histories. Everything downstream carries both. We model the merge — flow, sediment, temperature — because it changes everything below it.
What we measure
flow the two inflows, the one outflow mixing temperature and turbidity across the seam sediment what the tributary carries in naming which fork keeps the name, and why
Why it matters
Flood forecasts, fish passage, and water rights all hinge on the merge. Get the confluence right and the rest of the basin follows.
