WUNC 91.5 FM recently aired a story about GaugeCam – NC State Device Monitors Floods, Droughts:
“North Carolina has seen its fair share of both flooding and drought over the past several years. One of the problems has been getting accurate information, especially in rural areas. Francios Birgand is a biological engineering researcher at N.C. State. He led the development of the GaugeCam. He says he and his team wanted to explore the possibility of using wireless imaging technologies to help track water flows in streams and rivers.” Hear an excerpt of the interview with Dr. Birgand at WUNC’s web site.
The Abstract, North Carolina State University’s online newsletter, has an article that provides an overview of GaugeCam - Water Flow: A Picture’s Worth More Than A Thousand Words:
“From mitigating flood damage to managing water resources during a drought, tracking water flow is important. But tough budget times make maintaining data collection systems more difficult than ever. Researchers may have found a way to ease the problem, using a remote imaging system called GaugeCam.” Read the entire article at The Abstract’s web site.
Automated systems that measure water level usually rely on flow, pressure or ultrasound sensors. This approach, however, often return invalid results, as debris or sediment easily gets caught up in the sensors.
This motivated Dr. François Birgand of North Carolina State University to design an entirely new type of water level measurement system, based on The Imaging Source cameras. It is highly affordable and can record the water level of streams, rivers and even the ocean.
