Methods & Modeling

National Streamflow Statistics (NSS)


The NSS Program is a computer program that replaces the National Flood Frequency Program (NFF) to provide simple methods of estimating flood-peak discharges and low flow frequency/duration discharges.

Streamstats


StreamStats is a Web-based Geographic Information System (GIS) that provides users with access to an assortment of analytical tools that are useful for water-resources planning and management, and for engineering design applications, such as the design of bridges.

SWSTAT - Surface-Water Statistic


SWSTAT contains a number of options for statistically analyzing time-series data.

Streamgage Statistics Retrieval Tool


The “streamgage statistics” retrieval tool provides a table of basic summary statistics for the selected streamgage, as computed from daily values, for the period of record.

Other Surface Water Software


Assorted hydrologic, hydraulic, and statistical analysis software applications.
