Oregon Convention Center Portland, Oregon 9 - 12 July Abstract Two first-order forested watersheds (WS 80 and WS 77) on poorly drained pine-hardwood stands in the South Carolina Coastal Plain have been monitored since mids to characterize the hydrology, water quality and vegetation dynamics.

Effects of clearcut, cable logging on the hydrologic characteristics of a small coastal stream in Oregon indicate an average percent increase in sediment yield over a 7-year postlogging period. Annual runoff and high-flow volumes increased 19 and inches ( and 28 mm), respectively, after logging in the watershed.

The item Hydrologic changes after logging in two small Oregon coastal watersheds, by D. Harris represents a specific, individual, material embodiment of a distinct intellectual or artistic creation found in Indiana State Library.
Preliminary graphical analysis indicates that clear-cut logging of a small Oregon watershed has significantly altered certain hydrologic characteristics. After logging, moderate increases were noted in annual runoff, but no significant changes were detected in either peak or minimum flow by: Timber harvest in two small watersheds in western Oregon containing yr-old timber increased annual water yield up to 42 cm.
For 4 years after logging, yield increases averaged 38 cm at a ha clearcut watershed and 20 cm at a ha watershed where timber was shelterwood cut. The Alsea Watershed Study: effects of logging on the aquatic resources of three headwater streams of the Alsea River, Oregon.

As the hydrologic. Larger watersheds contain many smaller watersheds. It all depends on the outflow point; all of the land that drains water to the outflow point is the watershed for that outflow location.
Watersheds are important because the streamflow and the water quality of a river are affected by things, human-induced or not, happening in the land area "above" the river-outflow point.
Nutrient release from three small watersheds in Oregon's Coast Range was monitored for 2 years before and 2 years after logging. One watershed, Flynn Creek ( ha).

In the early s, about the time log- ging began, the study was broadened to include certain anions and cations. This case study describes the effects of road construction, timber harvest, and two methods of slash disposal on water quality of two small streams.

Oregon Coast Range. Three clearcut watersheds were selected for study; Deer Creek IV (39 acres) was clearcut, and Needle Branch ( acres) was clearcut and burned. Both watersheds were compared to Flynn Creek ( acres), an untreated control, before and after treatment. Change in hydrologic parameters was determined from differences between pre.
