Flooding is a natural phenomenon, widespread and common throughout the world, which can have a far-reaching effect on people and the environment. It is a rapid and excessive accumulation of water in a normally dry region caused by important and persistent atmospheric precipitations. The phenomenon is accentuated by some local characteristics such as the conditions and composition of the surface of the land, their slope and the topography of the place.
The ProgettoRIO , conceived by Flavio Falcinelli and financed by the companies RadioAstroLab and Fasar Elettronica , monitors waterways (ditches, canals, streams and rivers) reporting potential environmental risks due to floods that cause floods.
An interesting case study concerns the annual experimentation launched in October 2020 on the Misa river, a typical torrential watercourse that flows into the Adriatic Sea through the city of Senigallia (AN), in central Italy. The river, characterized by a very variable regime with frequent flood events, caused floods, some of which were particularly disastrous such as that which occurred in May 2014.
Monitoring involves sample measurements performed by the bridge on the provincial road of Bettolelle, a town about 7 km away in line d air from the center of the city of Senigallia. The site chosen for the surveys is optimal for an immediate and safe positioning of the instrumentation, offering ample visibility of the river basin in a location quite distant from the city of Senigallia in order to report, with sufficient advance, possible flood events with risk of flooding. The instrumentation used is portable, battery powered, each time positioned for the measurement and subsequently removed. The final objective of the experimentation is the installation of an automatic fixed station that continuously records the evolution of river parameters to provide a representation with high temporal resolution, very precise, of the observed scenario. By measuring some parameters of the river area and the local tropospheric perturbations on a daily basis, the data are processed to generate graphs that represent how the percentage of flooding of the basin, the dynamics of the waters, the frequency and the rainfall intensity. This information displays the conditions of the river in real time, signaling potential dangerous situations for the population and the environment.
The aim is to demonstrate to the institutions the effectiveness of a river surveillance system that uses innovative and low-cost instrumentation, designed and built by local companies, to provide a public utility service and civil protection.
The evolution of the project involves the installation of a fixed network of sensors strategically positioned in the territory and the development of an IT system suitable for managing the information coming from the various devices, obtaining the right tool to keep the observed river under control.
