Sources of seasonal water-supply forecast skill in the western US
Michael Dettinger
2007, Conference Paper, AGU Fall Meeting: 10-14 December 2007, 40 years in San Francisco, Calif.
Many water supplies in the western US depend on water that is stored in snowpacks and reservoirs during the cool, wet seasons for release and use in the following warm seasons. Managers of these water supplies must decide each winter how much water will be available in subsequent seasons so...
Regionalized equations for bankfull-discharge and channel characteristics of streams in New York State — Hydrologic Region 3 east of the Hudson River
Christiane I. Mulvihill, Barry P. Baldigo
2007, Scientific Investigations Report 2007-5227
Equations that relate drainage area to bankfull discharge and channel characteristics (such as width, depth, and cross-sectional area) at gaged sites are needed to define bankfull discharge and channel characteristics at ungaged sites and can be used for stream-restoration and protection projects, stream-channel classification, and channel assessments. These equations are...
