HYDROLOGY OF A DRAINAGE BASIN ON THE ALASKAN COASTAL PLAIN.
A 4-summer hydrologic record from a 1.6-sq km drainage basin at Barrow, Alaska is analyzed. The watershed, a drained lake basin, is underlain by continuous permafrost within 0.3 m of the tundra surface and is covered by ice-wedge polygons and numerous small shallow ponds. Considerable variations fro...

A 4-summer hydrologic record from a 1.6-sq km drainage basin at Barrow, Alaska is analyzed. The watershed, a drained lake basin, is underlain by continuous permafrost within 0.3 m of the tundra surface and is covered by ice-wedge polygons and numerous small shallow ponds. Considerable variations from the 20-yr means of summer climate (thaw period 88 days, precipitation 67 mm) are represented in the data; 1963 - cold, extremely wet; 1964 - cold, extremely dry; 1965 - cool, dry; 1966 - cool, wet. Runoff varied greatly from storm to storm, occurring primarily through and over the tundra mat and through an intricate system of polygonal troughs and ponds. As a result of the subdued coastal topography, varying areas (0.3 sq km to 1.6 sq km) contribute to runoff from different storms. Analyses of hydrographs revealed: (1) lag times generally from 3 to 10 hr; (2) recession constants of about 50 hr, but occasionally as much as 160 hr; and (3) runoff from individual storms between 1 and 70%. About 5% of the thaw season precipitation normally runs off.
