Measuring the Lumber River floodwaters
James Stonecypher measures flood waters from the Lumber River that breached a dam in Lumberton, North Carolina after the passage of Hurricane Florence, Sept. 17, 2018.
As Florence rains, rivers keep rising, submerging some USGS instrument
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.
Working to keep vital flood information flowing in the Carolinas
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.
USGS Scientists Get Ready for Hurricanes
A USGS hydrologic scientist installs a storm-tide sensor near the North Carolina coast as Hurricane Florence approaches.
USGS Storm-Tide Sensor for Hurricane Florence
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 methods used to make traditional discharge measurements with mechanical meters.
The ADCP measures water currents with sound,
