Abstract:Stream temperature and discharge each summer, water temperature and stream discharge are determined for the Kuparuk River. In many years, temperature and stream height were recorded manually each day. In recent years, data loggers have measured stream temperature and stream height at regular intervals. The Kuparuk River data is maintained by Dough Kane on the Water and Environmental Research Center at UAF (http://www.uaf.edu/water/projects/NorthSlope/upper_kuparuk/uk_river/uk_river.html) Stream height is converted into stream discharge based on a rating curve calculated from manual discharge measurements throughout the season. The principal investigator in charge of the temperature and discharge measurements is Dr. Breck Bowden.

Methods:Stage height measurements were taken daily 1 km upstream of the Kuparuk River crossing at the Dalton Highway. Measurements were taken at the water line and recorded using a measuring stick placed vertically on the upstream side between the two culverts. The readings were in centimeters up from the bottom of the river.

A new rating curve was developed from the 1990-1991 data, using six discharge measurements from 1990 and four discharge measurements from 1991. Discharge measurements taken in 1990 were found to be significantly different than those taken in 1991. Since it was uncertain that the 1990 numbers would provide sufficient information concerning the discrepancy between 1990 and 1991, the two years were plotted together using all ten measurements. The new rating curve used was y = -43.949081 + 1.569077x + (-0.018929)x^2+(0.000078294)x^3, with x as the stage height.

The percent error between measured discharges and those predicting using the new rating curve was between 22% at lower stage heights (80-100 cm) and 1% at higher stage heights (150 cm). The predicted values were found to be lower than the measured values.

Discharge measurements were taken using a Gurley meter. Calibration measurements were taken at 60% of depth at 0.5 meter increments along a cross sectional transect of the river, downstream of the culverts at the pipeline crossing. Raw data from calibration measurements are available.

Water temperature readings were taken hourly by a Campbell data logger positioned at the Kuparuk River Headwater Fork (68 33' 12"N;149 19' 30"W).
