Abstract A field study was made of the energy balances and the hydrologic balances of a 50-year old, 20 meter Douglas-fir stand and an adjacent clearcut during 1970 and 1971. The site, near Eatonville, Washington, was of low quality for Douglas-fir having developed on a glacial outwash terrace: the soils were well-drained. The objectives were to (1) obtain information about the effects of clear-cutting on the hydrologic and energy balances of the forest and (2) determine the actual and potential evapotranspiration rates during selected periods for the two areas. Actual evapotranspiration was determined with Bowen ratio approach of the energy balance and soil moisture extraction. (Author)
