National Streamflow Information Program home page describing the operation and maintenance of 7000 streamgages, overview of the program, system for collection of streamflow data, maintaining of historic streamflow data, and available reports.
Estimates of annual peak-streamflow frequency are needed for flood-plain management, assessment of flood risk, and design of structures, such as roads, bridges, culverts, dams, and levees.
A method of improving our estimates of statistics used to describe flood frequency, taking into account information obtained from the stream whose flood frequency is being investigated.
To better understand the exchange of groundwater and surface water, we coupled groundwater monitoring at the stream bank with nearby gages in the stream. Describes the procedure and results from several areas.
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.
