Why do you think they are called "floods"? Have you seen how high we build levees to contain a flooding river? I have seen rivers high up to the brim of the levee. Very eyebrow-raising. After that, the whole countryside is at jeopardy.
In my home county, the Nooksack River would seasonally flood the flatlands of its drainage, particularly the Lummi indian settlements in Marietta. Due to their status as wards of the government, they would decamp elsewhere, the flood would ruin their households, and they would receive replacement goods from the government upon subsidence of the floods. Farther upstream, in Lynden, the Dutch farmers settled on a highland and built dikes along the river to keep their fields from being flooded.
The flood canals I have seen in California and Texas are at least in the depth range you are talking about, but width also counts, as the two relate to total flow capacity.
