Sediment reservoir dynamics on steepland valley floors : influence of network structure and effects of inherited ages

Creator:: Frueh, Walter Terry
Abstract:: Sediment deposit ages inferred from radiocarbon dating of stream bank material were used to estimate residence times of valley-floor deposits in headwater valleys of the Oregon Coast Range, USA. Inherited ages of radiocarbon-dated material, i.e., time between carbon fixation in wood and its incorporation in a sediment deposit, can result...

Simulation of storm runoff in the Oregon Coast Range

Creator:: Fedora, Mark A.
Abstract:: Simulation of storm hydrographs in the Oregon Coast Range was explored using the Soil Conservation Service (SCS) curve number methodology, and by developing and testing an antecedent precipitation index (API) method. Standard SCS procedures over-estimated peak discharge by about a factor of two (i.e., average over-prediction of 118 percent). When...

Soil and hydrologic factors affecting the stability of natural slopes in the Oregon Coast Range

Creator:: Harr, R. Dennis (Robert Dennis), 1941- and Yee, Carlton S.
Abstract:: The work upon which this publication is based was supported by funds provided by the United States Department of the Interior, Office of Water Research and Technology, as authorized under the Water Resources Research Act of 1964 and by the United States Department of Agriculture, Forest Service, Pacific Northwest Forest...

A characterization of road hydrology in the Oregon Coast Range

Creator:: Gilbert, Erin H.
Abstract:: Forest roads alter hillslope hydrologic processes by intercepting, concentrating, and rerouting storm runoff. Current road drainage guidelines are based on minimizing erosion and do not take into account the impact of forest roads on hillslope hydrology. This work monitors ditch flow and rainfall for 10 road segments over the course...

Hydrology of five forest roads in the Oregon Coast Range

Creator:: Marbet, Christine Erica
Abstract:: Understanding the impact of low volume road networks on forested watersheds is important for future forest management and watershed restoration. This study characterized the hydrology of five segments of forest road in the Oregon Coast Range. Rainfall, infiltration, road surface runoff, and intercepted subsurface flow were measured at each road...

Climatic and physiographic controls on peakflow generation in the western Cascades, Oregon

Creator:: Perkins, Reed
Abstract:: Despite the importance of rain and snowmelt in causing peakflows in the Pacific Northwest, the interactive effects of a snowpack and watershed physiography on streamflow are largely undocumented. This study investigated the influence of soil and snowpack moisture on peakflow hydrograph shape in three small (< 60 ha) control sub-watersheds...

Hydrologic integration of forest roads with stream networks in two basins, western Cascades, Oregon

Creator:: Wemple, Beverly C.
Abstract:: This study assessed how logging-access roads may have contributed to observed historical increases in peak discharges associated with small and large logged basins in the western Cascades of Oregon. The study was conducted on the Lookout Creek (62km²) and the upper Blue River (118km²) basins. Potential road effects on hydrology...

Investigations of runoff production and sedimentation on forest roads

Creator:: Wemple, Beverley C.
Abstract:: Forest roads constructed in steep mountain landscapes have been associated with a number of effects on hydrologic and geomorphic processes. This research examined the effects of forest roads on the flow of water and sediment in drainage basins in the Cascade range of western Oregon. A study conducted at the...
