What Is an Integrated Road Flood Monitoring Sensor?

A road flood monitoring sensor is designed to detect water accumulation on urban infrastructure.

Unlike conventional hydrological water level monitoring, which usually measures rivers, lakes or reservoirs, road flood monitoring focuses on:

Surface water accumulation
Road ponding depth
Sudden urban flooding
Drainage system overflow

The sensor is installed directly into the ground surface.
