The Iowa Flood Center is dramatically expanding the scope of its river and stream sensor network across the state this fall.
The Flood Center, which has installed 200 river and stream gauges since 2010, will add an additional 50 sensors in collaboration with the Iowa Department of Natural Resources. These gauges monitor water levels in real time and send the data back to the Iowa Flood Information System (IFIS), which can be viewed by the public. Citizens, landowners and governments can then use this web-based tool to look for flood warnings, monitor water levels upstream from their location, and see exactly how far flood waters will reach in a given situation.
The sensors, which are usually installed on bridges, measure the distance to the water by sending an electronic pulse every 15 minutes. The availability of such precise measurements has already had a significant impact on local businesses, especially those located in floodplains. The sensors, which cost around $3,500 each, can save businesses thousands more by preventing losses in production and labor during flood season.
Iowa Flood Center staff and students will install the new sensors over the coming weeks. Watch the video below to learn more about how these sensors are installed across the state.
