Hampton Roads Benchmark Monitoring Network

The southern Chesapeake Bay region is experiencing land subsidence along with rising sea levels, both of which can contribute to coastal flooding. The rates at which these two processes are occurring are not exactly known. Mapping of land elevation change requires ground-truth survey data at multiple locations that are accurate and precise. With the exception of a few CORS sites that have...

Hydroacoustic Applications: Technological Advancements in the Streamgaging Network

In the mid-1990s, a new technology emerged in the field of inland streamflow monitoring. The South Atlantic Water Science Center is making great use of the acoustic Doppler current profiler (ADCP). It was originally developed for oceanographic work, but was adapted for inland streamflow measurements. This instrument is transforming the U.S. Geological Survey (USGS) streamgaging program.
