Ground-water inflow to the Deschutes River near the Warm Springs Indian Reservation, Oregon, August 1985 Ground-water inflow to the Deschutes River near the Warm Springs Indian Reservation, Oregon, August 1985
Groundwater inflow to the Deschutes River near the Warm Springs Indian Reservation in Oregon was estimated for August 1985 by: (1) measuring streamflow at various sites along the river; (2) determining the part of the streamflow that is groundwater inflow; and (3) analyzing the hydraulic gradients of the groundwater flow system to estimate the amount of groundwater discharge to the...

Quality of bottom material and elutriates in the lower Willamette River, Portland Harbor, Oregon Quality of bottom material and elutriates in the lower Willamette River, Portland Harbor, Oregon
In October 1983 the U.S. Geological Survey, in cooperation with the U.S. Army Corp of Engineers, collected bottom-material and water samples from Portland Harbor, Oregon to determine concentrations of trace metals and organic compounds in elutriate-test filtrate and bottom material. Of the trace metals examined in bottom material, concentrations of cadmium slightly exceed those of local...

Lithology, thickness, and extent of hydrogeologic units underlying the East Portland area, Oregon Lithology, thickness, and extent of hydrogeologic units underlying the East Portland area, Oregon
The lithology, thickness, and extent of eight distinct hydrogeologic units are described and mapped within the East Portland area of Oregon. The thickness, extent, and top of each unit are shown on contour maps at scales of 1:24,000. Their stratigraphic relations are displayed on a diagrammatic cross section. The geologic setting and unit lithology are described within the text. A data...

Review of edgematchimg procedures for digital cartographic data used in Geographic Information Systems (GIS) Review of edgematchimg procedures for digital cartographic data used in Geographic Information Systems (GIS)
In the process of developing a continuous hydrographic data layer for water resources applications in the Pacific Northwest, map-edge discontinuities in the U.S. Geological Survey 1:100 ,000-scale digital data that required application of computer-assisted edgematching procedures were identified. The spatial data sets required by the project must have line features that match closely...

The effects of two multipurpose reservoirs on the water temperature of the McKenzie River, Oregon The effects of two multipurpose reservoirs on the water temperature of the McKenzie River, Oregon
A one dimensional, unsteady-state temperature model using the equilibrium temperature approach (with air temperature used to estimate equilibrium temperature) is used to evaluate the effects of two Army Corps of Engineers dams and resulting reservoirs on the McKenzie River, from Delta Park (River Kilometer 99.9) to Leaburg Dam (River Kilometer 62.4). Both Corps of Engineers projects are...

U.S. Geological Survey ground-water studies in Oregon U.S. Geological Survey ground-water studies in Oregon
The use of groundwater in Oregon is expected to increase owing to continued population growth and to surface water supplies that are inadequate to meet present or future demand. The major groundwater issues in Oregon are: conjunctive use of surface and groundwater; contamination from hazardous wastes, leakage from underground gasoline and diesel tanks, naturally occurring brackish water...

Simulation of three lahars in the Mount St Helens area, Washington using a one-dimensional, unsteady-state streamflow model Simulation of three lahars in the Mount St Helens area, Washington using a one-dimensional, unsteady-state streamflow model
A one-dimensional, unsteady-state, open-channel model was used to analytically reproduce three lahar events. Factors contributing to the success of the modeling were: (1) the lahars were confined to a channel, (2) channel roughness was defined by field information, and (3) the volume of the flow remained relatively unchanged for the duration of the peak. Manning 's 'n ' values used in...
