Abstract:: Characteristics of low flows of nine streams in eastern Oregon were explored using long-term streamflow records. Year-to-year dependence of low flows is highly significant for streams in the Blue Mountain and the southeastern Oregon regions. Low streamflows increased over the period of record for seven of the selected streams. Flow...

Creator:: Surfleet, Christopher G.
Abstract:: Precipitation data from 1988-1995 for 13 rain gauges of the Department of Forest Engineering rain gauge network, and a longer precipitation record, 1976-1995, at Mapleton were analyzed. The objectives were to assess the spatial and temporal distribution of precipitation intensity and antecedent precipitation, and understand the role of these characteristics...

Creator:: Kowalski, Andrew S.
Abstract:: Occult deposition is the direct uptake of cloudwater by vegetation that comes into physical contact with wind-driven cloud droplets. This can be a significant pathway for hydrological and chemical fluxes from the atmosphere to some forests. Methods for estimating cloudwater fluxes to forests are reviewed. Previous studies have neglected the...

Creator:: Twining, David S.
Abstract:: The relationship between the outgoing long-wave radiation (OLR) field over the tropical Pacific and wintertime monthly precipitation for the western U. S. is investigated, using the mid-latitude upper-air circulation as an intermediary. Principal components (PC's) of the 500mb monthly averaged height field over the NE Pacific and western North America...

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...

Creator:: Hevesi, Joseph A.
Abstract:: Estimates of average annual precipitation (AAP) are-needed for hydrologic modeling at Yucca Mtn., Nevada, site of a proposed, high-level nuclear waste repository. Historical precipitation data and station elevation were obtained for stations in southern Nevada and southeastern California. Elevations for 1,531 additional locations were obtained from topographic maps. The sample...

Creator:: Dolph, Jayne Ellen
Abstract:: Characterizing the distribution of precipitation at regional scales is a requirement for the development of regional scale, spatially distributed hydrologic water balance models. This study performs a preliminary assessment of the utility and limitations of historical hydro-meteorological data for providing spatially distributed precipitation estimates over large areas. The historical data...
