![]() The third method used to measure water stages is called a pressure transducer. “And so using the calculations that the algorithm runs behind the scenes in the radar, it tells you how far it is down to the river level and back.” “It shoots a radar beam down to the top of the river, it reflects off the top of the river and back up to the radar sensor,” Wilson said. ![]() (National Weather Service)Ī radar gauge is an automated gauge attached to the side of a bridge. ![]() When in use, a radar beam is shot to the surface of a river and reflects back up to the radar sensor, which calculates how far it is from the river and back. “So we prefer some of our more high tech methods, but we still use those in locations where either flooding is infrequent or funding for an automated gauge just isn’t available.” Wilson said.Ī radar gauge is pictured in an undated photo contributed by the National Weather Service. Because these are manual measurement tools, the readings are subject to human error. Wire weights and staff gauges are manual measurement tools that are cheap to install and maintain. Someone gathering the water level will open the box and lower the weight down until it hits the top of the water.Ī staff gauge is like a large ruler that measures water surface elevation. Those boxes hold a metal winch with a weight on the bottom of it. If you drive along bridges over rivers, you may notice a wire weight box attached to the bridge. A wire weight is a manual measurement tool that is subject to human error. Wilson said there are a few tools used to measure river stages: a wire weight, a staff gauge, a radar gauge and a pressure transducer.Ī wire weight gauge is pictured in an undated photo contributed by the National Weather Service. Large, flowing rivers can dilute pollution more effectively than small, stagnant bodies of water. According to the Environmental Protection Agency, flow impacts water quality and which organisms can live in a river. That measurement is used to translate stage into flow.
