Landslide Studies in the Pacific Northwest
Landslides of various types in forest lands of the Pacific Northwest have been the subject of many studies over the past three decades. Research themes have included effects of geology, topography, climate, and forest land use (mainly clearcutting and roads) on landslides and effects of landslides on forest and stream ecosystems. We have compiled this listing in response to interest in the subject triggered by recent flooding and landslides.
The purpose of this document is to identify selected publications and theses/dissertations concerning landslides in the Pacific Northwest. Listed below are citations for landslide-related (debris slide, debris flow, earthflow) literature from USDA Forest Service Pacific Northwest Research Station scientists based in the Forestry Sciences Lab., Corvallis, Oregon, and cooperating scientists and students. This is a partial list. A great deal of additional literature is available on this subject. See, for example, "Sidle, R.C., Pearce, A.J., O'Loughlin, C.L. 1985. Hillslope stability and land use. Water Resources Monograph Series 11. Amer. Geophysical Union. 140 p."
Copies of theses and dissertations are available through Interlibrary Loan from the university where the degree program was completed. Reprints of publications are available from Tami Lowry, Forestry Sciences Lab., 3200 SW Jefferson Way, Corvallis, OR 97331 or lowryt@fsl.orst.edu.
