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,

USGS Scientists Mark a High-Water Mark in Louisiana

Daniel McCay and Chris Henry, USGS hydrologic technicians, use a level to draw a line on a high-water mark August 26. In most circumstances, when a high-water mark is flagged it would then be surveyed with GPS equipment to obtain its exact coordinates and elevation. However, because of the possibility of more storms hitting Louisiana the teams were initially only

Looking for High-Water Marks

Daniel McCay and Chris Henry, U.S. Geological Survey hydrologic technicians, search a neighborhood south of Denham Springs, Louisiana, for high-water marks August 26. The term high-water mark refers to the debris flood waters will leave on walls, buildings and trees. This thin line of residue is an indicator of how high the waters reached, yet the fragile nature of

Recording a High-Water Mark

Jonathan Gillip, USGS hydrologist, documents a high-water mark he flagged near a damage retirement community in Denham Springs, Louisiana, August 26. So far, USGS teams have flagged and surveyed more than 400 high-watermarks across southern Louisiana.
