Understanding Floods | Long-term Streamflow Data Collection (AD)
The USGS is developing methods to improve data collection during floods to gain new insight into the rise and fall of flood waters. In the past, the only data left behind after a flood was how high the water got, or the peak of the flood. This video presents the methodology that hydrologists are using to set up a Continuous Slope-area Reach in remote areas that are inaccessible during floods, providing data on water level every 5-minutes during a flood event. With this new process, USGS hydrologists can more accurately report and measure future flood flows and their effects.
