Collection of High-Water Mark Data at Selected Roadway Crossings To Document October 2016 Flooding in the Pee Dee and Waccamaw River Basins of South Carolina

Hurricane Matthew generated large amounts of rainfall in South and North Carolina during September/October 2016. The South Atlantic Water Science Center, in cooperation with the South Carolina Department of Transportation, recorded High-Water Marks along selected road crossings, within the Pee Dee and Waccamaw River Basins of South Carolina.

Coral Disease

We investigated coral disease processes and causes by characterizing microbial communities in diseased and healthy representatives of selected coral species both temporally and spatially by employing microarray technology. We tested the diagnostic potential of coral fluorescence for identifying disease-induced physiological stress.

DroughtWatch: Surface Water Conditions in Tennessee

The U.S. Geological Survey (USGS) has a network of surface-water real-time monitoring stations in Tennessee. The network provides real-time water-stage data along with computed streamflow at many of these locations, and rainfall recorded at some stations. These sites continuously record data on 15-minute intervals and transmit the data via satellite to be incorporated into the USGS National...

Simulating wave runup on an intermediate–reflective beach using a wave-resolving and a wave-averaged version of XBeach

The prediction of wave runup, as well as its components, time-averaged setup and the time-varying swash, is a key element of coastal storm hazard assessments, as wave runup controls the transitions between morphodynamic response types such as dune erosion and overwash, and the potential for flooding by wave overtopping.
