» Kuparuk River 1988 summer temperature and discharge calculated from stage height.
Discharge was calculated from stage height. The calibration of the discharge regression equation was rechecked during the summer at two different stage heights, 82 and 112cm. Actual flow measurements were taken at the “top, middle and bottom” depth increments every 1 meter along a cross sectional transect of the river, just downstream of the gas pipeline crossing. Calibration measurements were taken using a Marsh-McBirney, Model 201 portable water current meter. When the stage was under 105cm the rating curve equation y = ((x - 70)^1.44 * 0.016/2) + 0.1, with x as the stage height, was used. When the stage was over 105cm the rating curve equation y = ((x - 70)^1.44 * 0.016) + 0.1, with x as the stage height, was used. Raw data from the calibration measurement and the actual chart recordings are available.
Some temperature data is available for this year. Temperature readings were taken with a 12” blunt stem reotemp dial-head thermometer at a location between the two culverts upstream of the road.
