Moving water in a storm/flooding situation should tell you to start that 200,000.00 RV up and drive away from the river and the low ground. Glad everyone is safe.

Hope everyone was insured👍

I think the water can be mitigated as a flow, by turning the fast straight current into a serpentine slowed set of stages: a little work will turn the river left and right several times, making a more determined river-bed that wont wander and erode the sides, but will meander the bore of the channel into slower deeper more-meaningful water's edge: it's called riparian-remediation, I strongly recommend channeling the funds into making it happen.

Motor homes. In my days they were "trailers".
