“…The lower Hudson Basin contributed 19% of water discharge at the study site computed as the difference in mean daily values from the study site and Federal Dam. Similarly, 19% was also computed based on the yields derived from Wappinger Creek, Wallkill, and Mohawk Rivers; these values are slightly lower than the 28% determined from data in Randall (1996) over the period 1951 to 1980.…”

“…Most of the following steps can readily be automated in a GIS, and the sequence of these steps is illustrated in a flowchart in appendix 1 ( fig. 1-1 • Amount of water available for runoff.-Calculate 1951-80 mean annual runoff for the watershed of interest from the mean annual runoff contours presented by Randall (1996). This can be done visually by superimposing the watershed outline on the contour map, or can be automated in a GIS.…”

“…The datasets for the present study included mean watershed altitude as calculated by the GIS from USGS 30-meter digital elevation models. The datasets also included 1951-80 mean annual precipitation and mean annual runoff, as interpolated by the GIS from contour maps by Randall (1996) that were drawn by using a protocol that forced the precipitation contours to parallel the runoff contours and ensured that each set of contours was constrained both by precipitation at precipitation stations and runoff from gaged watersheds.…”

AbstractA variety of watershed properties available in 2015 from geographic information systems were tested in regression equations to estimate two commonly used statistical indices of the low flow of streams, namely the lowest flows averaged over 7 consecutive days that have a 1 in 10 and a 1 in 2 chance of not being exceeded in any given year (7-day, 10-year and 7-day, 2-year low flows). The equations were based on streamflow measurements in 51 watersheds in the Lower Hudson River Basin of New York during the years 1958-1978, when the number of streamflow measurement sites on unregulated streams was substantially greater than in subsequent years. These low-flow indices are chiefly a function of the area of surficial sand and gravel in the watershed; more precisely, 7-day, 10-year and 7-day, 2-year low flows both increase in proportion to the area of sand and gravel deposited by glacial meltwater, whereas 7-day, 2-year low flows also increase in proportion to the area of postglacial alluvium. Both low-flow statistics are also functions of mean annual runoff (a measure of net water input to the watershed from precipitation) and area of swamps and poorly drained soils in or adjacent to surficial sand and gravel (where groundwater recharge is unlikely and riparian water loss to evapotranspiration is substantial). Small but significant refinements in estimation accuracy resulted from the inclusion of two indices of stream geometry, channel slope and length, in the regression equations. Most of the regression analysis was undertaken with the ordinary least squares method, but four equations were replicated by using weighted least squares to provide a more realistic appraisal of the precision of low-flow estimates. The most accurate estimation equations tested in this study explain nearly 84 and 87 percent of the variation in 7-day, 10-year and 7-day, 2-year low flows, respectively, with standard errors of 0.032 and 0.050 cubic feet per second per square mile. The equations use natural values of streamflow and watershed properties; logarithmic transformations yielded less accurate equations inconsistent with some conceptualized relationships.

“…The lowest elevations are about 750 ft above NAVD 88 along the Chemung River at Waverly, New York. Precipitation in the Chemung River Basin study area varies minimally across the area from 32 to 36 inches per year (in/yr) (Randall, 1996). Urban centers in the Chemung River Basin study area include Waverly, Elmira, Corning, Bath, Cohocton, and Hornell.…”
