Tide stage, specific conductance, water temperature, and freshwater inflow at selected Hudson River (New York) gages updated every 4-hours to measure the effects of freshwater withdrawals and upstream movement of the salt front.
Photographic survey of the impacts of Hurricane Katrina on the barrier islands, barrier shoreline, and the Mississippi River Delta along the Louisiana coastline. Primary focus is on the ecosystems such as fish, rookeries, and seagrass beds.
The Hydro-Climatic Data Network, or HCDN, consists of streamflow records for 1,659 sites throughout United States and its Territories. Records span the period 1874 through 1988, and represent a total of 73,231 water years of information.
Description and illustrations of hydroacoustic current meters for measuring the discharge in streams and rivers with links to wading discharge measurements, project progress and plans and references.
Technical information on acoustic methods of measuring water currents and applications of hydroacoustic techniques to problems in surface water hydrology.
Description of the hydrogeologic framework of Antelope Valley and Bedell Flat in west-central Nevada north of Reno-Sparks area. Gravimetric and seismic-refraction methods were used in the study. Report available in PDF format or HTML format.
Use of hydroacoustics by the USGS in Indiana to make streamflow measurements using Acoustic Doppler Current Profilers (ADCPs) and other hydroacoustic current meters.
The USGS collects continuous stage, discharge, and other instantaneous time-series data on the nations rivers. This Archive provides streamflow data and historical data, often several years worth.
