The report describes the results of model calibration and validation, and evaluates the extent to which runoff response to timber harvesting and increased road densities in East Fork Lobster Creek Basin can be simulated, using Precipitation-Runoff Modeling System (PRMS), a deterministic, destributed-parameter-modeling system.
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...
Measurements of temperature and salinity in the upper 5 m of the ocean
along the equator showed cool fresh anomalies due to rain showers. The
measurements were made between 140 W and 110 W during April 1987, an
El Nino year. The eastern equatorial Pacific was characterized by weak winds...
The Tualatin River Basin along the east side of the Coastal Mountains in Oregon is subject to a complex mixture of land uses. Approximately half the area is devoted to forestry production. The remainder is divided between agriculture and urban uses. In addition to this diversity in land use, there...
