D.D. Harris 1973 <p>Preliminary graphical analysis indicates that clear-cut&nbsp;logging of a small Oregon watershed has significantly altered certain&nbsp;hydrologic characteristics. After logging, moderate increases were noted&nbsp;in annual runoff, but no significant changes were detected in either&nbsp;peak or minimum flow rates. Both the annual sediment yields and the&nbsp;maximum monthly water temperatures increased greatly after logging;&nbsp;sediment yields and temperatures in the unlogged control watershed&nbsp;actually decreased during the postlogging period.</p> application/pdf en U.S. Geological Survey Hydrologic changes after clear-cut logging in a small Oregon coastal watershed article
