| Notes | “The Drift Creek watershed is a source of drinking water for the Confederated Tribes of Siletz Indians (CTSI) and Lincoln City and is a reproductive habitat for endangered salmon and trout species. The watershed has been designated as ‘Impaired by Unknown Stressors’ by the MidCoast Watersheds Council Biological Monitoring Results Survey (2013). The Oregon Department of Geology and Mineral Industries (DOGAMI), the Oregon Department of Environmental Quality (DEQ), and the CTSI suspect that landslides may be causing water quality deterioration. This study maps landslide distribution and landslide susceptibility; determines physical properties of landslide-prone soil and rock; and estimates soil loss resulting from landslide-derived sediment within 30 m of Strahler 3rd order or higher streams . . . Five hundred and seventy landslides were mapped. . . “ (from the Abstract). The upper parts of the watershed were more susceptible to landslides. Unfortunately, this was the area undergoing logging, which exacerbated sedimentation problems. The author developed a landslide susceptibility model and a soil loss model. These tools should be useful for future researchers. |
