Geographic variations in water quality and recreational use along the upper Wallowa River and selected tributaries

Creator:

McDowell, Theodore R.

Abstract:

Physical, chemical and bacterial water quality parameters of the upper Wallowa River were sampled periodically between July 2, 1978 and June 9, 1979 at nine stream and lake sampling sites. Water upstream from Wallowa Lake was typified by low nutrient concentrations ( generally below detectable limits except for nitrates), low....

Long-term effects of changes in vegetation condition, precipitation and watershed parameters on summer low-flows in the semi-arid Pacific Northwest

Creator:

Zeb, Aurang

Abstract:

Summer low-flow behavior in the semi-arid areas of the Pacific Northwest was studied. Long-term data from thirty-eight streams/rivers and thirty-six precipitation stations was exploited. The study area was divided into five zones based on annual average precipitation. Trends and patterns in summer low-flows and precipitation were identified. Different zones showed...

Incipient motion and particle transport in gravel-bed streams

Creator:

Matin, Habib

Abstract:

The incipient motion of sediment particles in gravel-bed rivers is a very important process. It represents the difference between bed stability and bed mobility. A field study was conducted in Oak Creek, Oregon to investigate incipient motion of individual particles in gravel-bed streams. Investigation was also made of the incipient...
