Andorra River Flow Tender

Being able to control and monitor the growth of river flows in major rain episodes allows to anticipate and preventively deploy the necessary means to minimize the impact of the phenomenon. To this end in 2017 the installation of a surveillance network was promoted with the distribution of a total of 9 stations strategically distributed throughout the country.The system is automatic autonomous through solar panels and self-powered battery and is usually installed on one side of the bridge. The sensor calculates the height of the river and this element is translated by means of hydraulic modeling in increase of the flow of the river. We establish parameters and pre-alert levels and when these are exceeded we receive notifications from Civil Protection and Fire said the director of Civil Protection Cristian Pons in the regular maintenance visit that has been made to the station installed in Llorts.In the event of river floods and significant episodes of rain a pre-alert is activated which in turn initiates an action plan and the operational resources planned to check the situation and activate the protocols that are in place are moved to the ground. necessary in the event of any impact on the territory. The episodes where more alerts are recorded are usually in the spring with thawing and in summer with heavy rains. Since 2017 the system has already pressed several times to activate this protocol.In addition the system also allows historical control of river flows and the use of this data to monitor the countrys water. The recorded data is sent continuously and automatically to the government server and can be viewed at any time said Armand Jesus manager of the company Bioma concessionaire of the installation and maintenance of the control network.
