HYDROLOGIC STUDIES OF THE GLENN CREEK DRAINAGE BASIN NEAR FAIRBANKS, ALASKA.

The following observations and tentative conclusions are based on the first summer's study of Glenn Creek and its drainage basin: (1) relationships comprising at-a-station hydraulic geometry are similar to those for larger streams in other areas; (2) the lag time between rainfall and peak storm...

Description
Summary:The following observations and tentative conclusions are based on the first summer's study of Glenn Creek and its drainage basin: (1) relationships comprising at-a-station hydraulic geometry are similar to those for larger streams in other areas; (2) the lag time between rainfall and peak storm discharge is much longer for Glenn Creek than for similar-sized streams in mid-latitude regions; (3) hydrograph recessions are drawn out in time relative to those for similar-sized streams in mid-latitude regions; (4) base flow was low in early and mid-summer, rose to a peak in late summer, and very gradually diminished thereafter, accounting for most of the flow in September and October; (5) direct runoff must occur largely as interflow; (6) about 24% of the rain which fell appeared as runoff; (7) the fraction of rainfall appearing as direct runoff varied from 3% to 30%, and showed no seasonal trends; () the suspended and dissolved sediment concentrations of Glenn Creek are within the ranges reported for larger streams in the area; (9) suspended sediment yield was roughly five times as large as dissolved sediment yield for June-October. A number of years of study will be required to confirm these preliminary conclusions and to determine the representativeness of the observations. (Author)
