资源简介：
Streamflow at 9 watersheds within the Hubbard Brook Experimental
Forest has been measured continuously from as early as 1955. Streams
are gaged with V-notch weirs at the outlet of each watershed. Through
2012, streamflow was recorded by means of a float attached
mechanically to a pen on a spring-wound strip-chart recorder. For each
day, 2 to 130 points on the chart trace were digitized, depending on
the rate of change of flow. Gage heights are converted to streamflow
rate by calibration and conversion factors. There is a discharge value
for every digitized point.
Beginning January 1, 2013, instantaneous streamflow data are measured
by electronic sensors, and data are provisional as the transition from
chart to digital data collection is still under evaluation. Data may
be updated before they are finalized. Please contact the dataset
creator prior to data use/publication.
These data were gathered as part of the Hubbard Brook Ecosystem Study
(HBES). The HBES is a collaborative effort at the Hubbard Brook
Experimental Forest, which is operated and maintained by the USDA
Forest Service, Northern Research Station.
