Stream Sensor Slideshow
Until recently, the high cost of building infrastructure, equipment, and maintenance meant that gauges to measure river and stream levels in Iowa were relatively rare. One of the Iowa Flood Center’s priorities has been to develop an affordable monitoring system to provide up-to-the minute data on Iowa’s streams and rivers. IFC students helped develop an electronic sensor to measure stream levels and transmit data back to the center. The sensor is placed on bridges and uses sonar to measure the distance from the water’s surface to the sensor. The information is transmitted via cell phone to a central database, and provides a time-sensitive picture of current stream levels.
