Flash flood warning system

Hydraulic and hydrological risk

Flash flood warning

Description

Powerful and sudden events such as flash floods can cause floods in a few hours and are becoming more and more frequent. For this reason there are quick and reliable systems capable of monitoring high intensity precipitation and the rising river levels generated by it at the same time. The objective is to timely alert the competent authorities and the population when critical thresholds are exceeded in order to enact the pre-established Civil Defense plans. These systems can also be configured to manage local alarms, e.g. traffic lights to automatically stop traffic, light panels or sirens.
