Volume of water in a stream passing a given point at a given moment in time, expressed as a measure of volume per unit of time, i.e. cubic feet per second, million gallons per day, or gallons per minute.
Site to locate most recent or archive reports for end-of-the-month hydrologic conditions with descriptions, data, charts, and maps giving an overview of water conditions during the month for the state of New York.
Links to model documentation, search engine, and help for (FEQ) Full Equations (a computer model for one-dimensional unsteady flow in open channels and through control structures), and the Full Equations Utilities package (FEQUTL).
Portal for Missouri River Infolinks, a clearinghouse to multiple links giving Missouri information, photo gallery, river weather forecast, projects and features, maps, meetings, history, and science research.

Explains 16 distinct types of scientific information that are needed to understand climate change, including the specific parameters measured, why they are needed, who measures them, and the type and amount of information that are not yet available.
Stream discharge and nitrate concentration increased downstream of the burned area during snowmelt, but these were probably within the treatment capacity of most drinking-water plants, and limited changes were observed in downstream ecosystems.
