The Ebro River Basin Authority (CHE) is seeking to strengthen the sensor network of the Automatic Hydrological Information System (SAIH) in response to episodes of very heavy rainfall. These events can leave large amounts of water in a very short time and cause rapid rises and unusually high flows, especially in ravines and smaller watercourses.
GREATER MONITORING DURING TORRENTIAL RAIN
The difficulty of accurately predicting these events makes real-time monitoring particularly important. Telemetry stations make it possible to track how rainfall and watercourses evolve and transmit that information to the hydrological control system, improving the ability to promptly detect potentially adverse situations.
Currently, the Ebro's Integrated Automatic Hydrological Information System has more than 1,500 stations and control points, generating around 15,000 measurement, monitoring and control signals. The information reaches the SAIH Data Processing Center every 15 minutes and includes data such as river and reservoir levels, water temperature and recorded rainfall.
18 MONTHS TO COMPLETE THE INSTALLATION
The work began last August and is expected to take 18 months. Once all the equipment has been installed, the CHE will have a denser sensor network to monitor the development of heavy rainfall events and more accurately detect their possible effects on watercourses in the Ebro basin.
