Smith, J.B., Godt, J.W., Baum, R.L., Coe, J.A., Ellis, William, and Burns, S.F., 2017, Results of hydrologic monitoring of a landslide-prone hillslope in Portland's West Hills, Oregon, 2006-2017: U.S. Geological Survey data release,


The West Hills of Portland, in the southern Tualatin Mountains, trend northwest along the west side of Portland, Oregon. These silt-mantled mountains receive significant wet-season precipitation and are prone to sliding during wet conditions, occasionally resulting in significant property damage or casualties. In an effort to develop a baseline for interpretive analysis of the groundwater response to rainfall, an automated monitoring system was installed in 2006 to measure rainfall, pore-water pressure, soil suction, soil-water potential, and volumetric water content at 15-minute intervals. The data show a cyclical pattern of groundwater and moisture content levels—wet from October to May and dry between June and September. Saturated [...]
