flood gauge
River level monitor
A flood gauge is a marker showing water levels during floods, typically a vertical post or wall marking calibrated in feet or meters.
Gauges may be installed at bridges, riverbanks, or coastal areas to monitor rising water and trigger evacuation warnings.
Historical flood gauges record high-water marks from past events: The 1927 flood gauge showed water twelve feet above normal.
