Excerpt from Streamflow After Patch Logging in Small Drainages Within the Bull Run Municipal Watershed, Oregon
Changes in annual water yield, mini mum streamflow, and instantaneous peak flow (the maximum rate of streamflow caused by a rain or snow melt event) are all important in municipal watershed management. If timber cutting can increase water yield, then a municipal watershed might be made to yield more water, particularly during the summer period of low flow. Increased size of peak flows as a result of timber harvest might be associated with not only overland flow and attendant surface erosion but also erosion of stream channels. Both factors could adversely affect water quality.
In 1955, the usda Forest Service and the City of Portland, Oregon, began a cooperative study to determine effects of timber harvest on water yield and timing of runoff and the quality of streamflow in three small watersheds within the Bull Run Municipal Watershed. This report deals only with changes in quantity and timing of streamflow.

Paperback. Zustand: New. Print on Demand. This insightful book explores the compelling relationship between forestry methods and streamflow within the Bull Run Municipal Watershed in Oregon. Through meticulous research and data analysis, the author demonstrates the impact of patch logging on streamflow characteristics, particularly annual water yield, low flows, and peak flows. By comparing pre-logging and post-logging conditions across small experimental watersheds, the author uncovers valuable insights into how logging practices can influence water resource availability and timing. The findings elucidate the effects of logging on stream ecosystems, highlighting the complexities of forest-water interactions and informing strategies for sustainable watershed management. This book will fascinate readers interested in forestry, hydrology, and the sustainable management of natural resources, providing a solid foundation for decision-making and future research within these fields.
