Measuring a high water mark as flooding recedes
USGS hydrographer Kyle Marchman measures a high water mark on the rear wall of a Kangaroo gas station on Highway 24 north of Fayetteville, NC on Sept. 18, 2018, after flooding caused by Hurricane Florence.
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,
