Ten new automatic water level gauges, delivered under the FAIRway Danube project, are now fully operational. They measure the water level and temperature on ten locations along the Bulgarian section – from Gomotarci village upstream to Malak Preslavets downstream. Two of them are mounted on the Vidin-Kalafat and Ruse-Giurgiu bridges. One of the gauges is floating – it’s fixed on a buoy, while the sensor is attached to the anchor. Such configuration is used for the first time on the Bulgarian stretch of the Danube. All gauges are electrically autonomous as they are power supplied by solar panels. The data, collected by the gauges, automatically transmits to a special data-base server and is used for the water level forecast, as well.
