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.
