Public ISBD Titre de série : US geological Survey Water Supply Paper, 2073 Titre : Hydrologic changes after logging in two small oregon coastal watersheds Type de document : texte imprimé Auteurs : Harris, D. D. Mention d'édition : US. Government Printing Office Editeur : US. Government Printing Office Année de publication : 1977 ISBN/ISSN/EAN : CI-10781 Note générale : The sduty described in this report is part of a large interdisciplinary research study started in 1957. To investigate the effects of logging, three small watershed in the Alsea river basin on the west slop of the oregon coast range were chosen for the study. Hydrologic data were collected on all three streams for 15 year beginning in the 1959 water year/ the data cover 7 years before logging, 1 year during loging and 7 years after loging. The purpose is to present the results of the evaluation of changes in streamflow, sedimentation, and water temperature after logging.
