Abstract |
Four studies were conducted. The first was to determine average annual and seasonal water yields, flow duration, and high daily flows for 137 watersheds and to relate these, insofar as possible, to the seven major physiographic regions in the Northeast. In the second study, the relationships of average annual and seasonal discharges, flow-duration discharges, and high daily flow discharges to selected climatic, geographic, topographic, and land-use variables were investigated. This analysis was extended in the third study to better define the relationships between the water yield parameters and the climatic and physical watershed variables within each of the physiographic regions. The fourth study was concerned primarily with the determination of the representativeness of the small experimental watersheds in relation to the physiographic region in which they are located.
