A WaterWatch web map shows streamgages in North and South Carolina that approached or exceeded major flood stage EST on September 19, 2018, as the former Hurricane Florence, now downgraded to a tropical depression, deluged the states with rain.
David Stillwell, USGS hydrologic technician, performs a discharge measurement to help document and forecast flooding caused by Hurricane Florence at Long Creek in Rhyne, North Carolina on Sept. 16.
A USGS storm-tide sensor, deployed in advance of Hurricane Florence's landfall. The sensors are housed in vented steel pipes a few inches wide and about a foot long. They are being installed on bridges, piers, and other structures that have a good chance of surviving the storm.
The information the sensors collect will help define the depth and duration of a storm...

Acoustic Doppler Current Profiler (ADCP) to measure streamflow
The use of acoustic Doppler current profilers (ADCPs) from a moving boat is now a commonly used method for measuring streamflow. The technology and methods for making ADCP-based discharge measurements are different from the technology and...
