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. 

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 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.

The USGS Coastal Change Hazards Storm Team has forecast coast-wide levels of beach erosion, inundation and overwash due to Hurricane Florence's expected path and landgfall.

The Coastal Change Hazards Storm Team has forecast changing water levels at specific locations over time.

GeoGirls take core samples at a pond near the Hummocks Trail to study groundwater transport.

The GeoGirls examined tephra (ash and pumice) deposits from Mount St. Helens’ eruptive past and learned how to create a stratigraphic column.
