Available in PDF, EPUB and Kindle. Book excerpt: The effect of logging and roadbuilding on erosion and sedimentation are analyzed by comparing the North Fork and South Fork of Caspar Creek, in northern California. Increased sediment production during the 4 years after road construction, was 326 cu yd/sq mi/yr-80 percent greater than that predicted by the predisturbance regression analysis. The average sediment load during the 3 years of logging increased by 957 cu yd/sq mi/yr-275 percent greater than the predicted values. Although the erosion or sediment increases do not appear to be degrading site quality, average turbidity levels in the South Fork exceeded water quality standards.

This book was released on 1970 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of roadbuilding, logging and burning upon stream runoff responses to individual storms are evaluated for the Alsea experimental watersheds, located in the Oregon Coast Range, The parameters analyzed are peak discharge, induced peak discharge, time-to-peak, and storm-runoff volume. The volume parameter is further sub-divided into total, quick, delayed, rising limb and falling limb flows. The control-watershed approach and linear regression method are utilized in this study. Calibration of the main stations at Flynn Creek (502 acres) and Deer Creek (750 acres) started in 1958. That for subwatershed DC II (138 acres) and DC III (100 acres) started in 1962. Watershed treatments included differing amounts of roadbuilding in the summer of 1965 and logging in 1966. The percentages of each watershed area subject to roadbuilding and to logging, respectively, were: Deer Creek main station, 3.7% and 26% of area in roads and logging, respectively, DC II, 3.1% and 20%, and DC III, 12, 1% and 72%, One small portion on the main watershed also received burning treatment in 1967, Flynn Creek was preserved in its natural state as a control. Data were analyzed through 1968. The storm-runoff responses of the treated watershed were found to relate to the type of treatment applied and percent of area treated, Roadbuilding resulted in significant increases in peak and induced peak discharges on DC III, which was subjected to the most intensive treatment. Logging generally demonstrated a more pronounced effect on runoff than did roadbuilding, since more vegetation was removed. Although highly significant augmentations in peak and induced peak discharges were detected after logging on subwatershed III, only minor changes were observed at the main Deer Creek outlet, The time-to-peak parameter was generally not affected by the land manipulations in this study. Separation of the annual data into the assumed recharging and recharged periods, based on antecedent soil moisture conditions, was selected for seasonal comparison over the use of an arbitrary cutoff date. Changes in flow volume parameters due to roadbuilding were insignificant. Rising limb flow on DC III as well as at the Deer Creek main station was moderately increased after logging. Although an increase in delayed flow and a decrease in quick flow occurred at the main station, these are considered to be compensating errors. Effects on design floods after treatments were indicated by the sharp increases in peak discharges, based upon flood frequency and statistical analyses.

This book was released on 2007-12-03 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alsea Logging and Aquatic Resources Study, commissioned by the Oregon Legislature in 1959, marked the beginning of four decades of research in the Pacific Northwest devoted to understanding the impacts of forest practices on water quality, water quantity, aquatic habitat, and aquatic organism popu- tions. While earlier watershed research examined changes in runoff and erosion from various land uses, this study was the first watershed experiment to focus so heavily on aquatic habitat and organism response to forest practices. The Alsea Watershed Study, as it came to be known, extended over 15 years with seven years of pretreatment calibration measurements, a year of treatment, and seven years of post-treatment monitoring. The research was a cooperative effort with scientists from Oregon State University, Oregon Department of Fish and Wildlife, the U.S. Geological Survey, and the U.S. Environmental Protection Agency. Cooperating landowners included the Georgia-Pacific Corporation, the U.S. Forest Service, and a local rancher. It was a remarkable 15-year partnership marked by excellent cooperation among the participants and outstanding coordination among the scientists, many of whom participated actively for the entire period.

The measured hydrologic changes are compared to those predicted by a methodology commonly used in the Forest Service's Northern Region, the equivalent clearcut area procedure. lncreases in peak streamflows are discussed with respect to their potential to modify the channel system.
