When precipitation falls on frozen soil, serious soil loss can
occur. In order to assign realistic probabilities to the occurrence of
this condition for use in predicting erosion rates over long time
periods, a technique for combining characteristics of precipitation and
air temperature records is applied to more than 31...
The occurrence of frozen soil has a major effect on runoff and soil loss in western Oregon. Hence, information regarding the probabilities of occurrence of periods during which the soil may be frozen is necessary in order to adequately forecast long-term erosion rates for this region. In order to assign...
Periods of precipitation with certain combinations of characteristics
(e.g„ high intensity rainfall on saturated soil) can lead to appreciable
soil loss in western Oregon. In order to assign realistic probabilities to
the occurrence of these periods for use in predicting long-term erosion rates,
a soil erosion-specific definition of a precipitation...
When precipitation falls on frozen soil, serious soil loss can
occur. In order to assign realistic probabilities to the occurrence of
this condition for use in predicting erosion rates over long time

The Weather Radar Set An/CPS-9 at McCulloch Peak,
Oregon, provided data of changes in radar precipitation
echo patterns in the vicinity of Marys Peak. Echo heights
studied from data collected on 14 March 1963 averaged nearly
the same upwind, directly over Marys Peak, and downwind.
For the data of 28...
The semi-arid regions of the Pacific Northwest are
characterized by a high degree of annual temperature and
precipitation variation. As a result of this climatic
variation, dryland nitrogen fertilizer trials on fallow-
,wheat rotations typically demonstrate a variable response.
Wheat growers in the area must not only cope with this...
