HYDROLOGY OF THE GLENN CREEK WATERSHED, TANANA RIVER BASIN, CENTRAL ALASKA

THE RESULTS OF A FOUR-SUMMER (1964-1967) HYDROLOGIC STUDY OF THE WATERSHED OF GLENN CREEK, ABOUT 8 MILES NORTH OF FAIRBANKS, ALASKA, IN THE YUKON-TANANA UPLANDS PHYSIOGRAPHIC PROVINCE, ARE PRESENTED. THIS WORK WAS INITIATED TO PROVIDE INITIAL BASE LINE HYDROLOGIC DATA FOR A SMALL SUBARCTIC WATERSHED, THE FIRST DETAILED STUDY IN THE DISCONTINUOUS PERMAFROST ZONE OF THE NORTH AMERICAN TAIGA. STANDARD HYDROLOGIC AND METEOROLOGIC INSTRUMENTATION WAS USED, AND STREAMFLOW CHARACTERISTICS WERE ANALYZED BY STANDARD HYDROGRAPH-ANALYSIS TECHNIQUES. THE STREAM IS SECOND-ORDER, AND DRAINS AN AREA OF 0.70 SQUARE MILE. BASIN ELEVATIONS ARE FROM 842 FT TO 1,618 FT. IN REGARD TO TOPOGRAPHY, GEOLOGY, SOILS, PERMAFROST, VEGETATION, AND CLIMATE, THE WATERSHED SEEMS TO BE REPRESENTATIVE OF LOW-ORDER, LOW-ELEVATION DRAINAGE BASINS IN THE PROVINCE. ANALYSIS OF RAINFALL-RUNOFF DATA INDICATES THAT ABOUT HALF THE 12.3-IN. NORMAL ANNUAL PRECIPITATION IS RUNOFF. ANALYSIS OF HYDROGRAPHS AND KNOWLEDGE OF THE PHYSICAL CHARACTERISTICS OF THE BASIN INDICATE THAT STORM RUNOFF OCCURS INITIALLY AS SURFACE RUNOFF FROM BARE SOIL AREAS ADJACENT TO THE STREAM, WHILE RECESSIONS ARE DOMINATED BY A COMBINATION OF TUNNEL FLOW BENEATH MOSS-COVERED PARTS OF THE BASINS AND TYPICAL GROUNDWATER FLOW THROUGH THE MOSS AND SOILS. PEAK DISCHARGES FOR INDIVIDUAL STORMS COULD BE WELL ESTIMATED BY AN EQUATION INCLUDING ANTECEDENT DISCHARGE, TOTAL PRECIPITATION AND STORM DURATION, AND AVERAGE RECESSION CONSTANT. /AUTHOR/
