Full Text:: WATERSHEDS IN WESTERN OREGON VOLUME I: ANALYSIS Jonathan D. Istok Larry Boersma John S. Hickman M. E

Creator:: Brown, Barbara G., Istok, Jonathan D., Katz, Richard W., and Murphy, Allan H.
Abstract:: Periods of precipitation with certain combinations of characteristics (e.g., high intensity rainfall on saturated soil) can lead to appreciable soil loss in the Pacific Northwest. 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...

Creator:: Istok, Jonathan D., Brown, Barbara G., Boersma, Larry, Katz, Richard W., and Murphy, Allan H.
Abstract:: 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...

Creator:: Brown, Barbara G., Istok, Jonathan D., Katz, Richard W., Murphy, Allan H., and Boersma, Larry
Abstract:: The occurrence of frozen soil has a major effect on runoff and soil loss in the Pacific Northwest. 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...

Abstract:: 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 hourly wet season...
