  	Citation × Citation Citation Abstract Copy Title: From the Grapevine. v.1,n.1, Spring 2014 Author: Vinay Pagay, Southern Oregon Research and Extension Center (Or.) Year: 2014 The Southern Oregon Research and Extension Center (SOREC) is recognized throughout Southern Oregon for its deep commitment to and support of agricultural research, sustainable growing practices, humane animal husbandry and healthy living. Historically, SOREC consists of the Jackson County Extension Service and the Southern Oregon Experiment Station. Both of SOREC’s units serve as the front door to Oregon State University, Oregon’s Land Grant University, and its resources. In addition to its support of farming and ranching, SOREC maintains demonstration fields, and also runs community programs such as Master Gardeners, 4-H, Food Preservers, Land Stewards. SOREC staff was instrumental in the growth of the pear industry in Southern Oregon and spearheaded the emergence of grape growing and wine making in the 1970s and 1980s. The Southern Oregon Experiment Station was established in 1911, and was located south of Phoenix at the Jackson County Poor Farm where the Dog Pound is located today. There were three other local Experiment Stations until 1958 when all were combined and relocated to the current Hanley Road location. The Extension office was first located in 1914 in the basement of the Jackson County Courthouse, later moving to Maple Grove Drive in south Medford, next to the old Fair Grounds. When the county began development of the south Medford I5 interchange in 1994, the Extension was moved to the Hanley Road location.

  Citation × Citation Citation Abstract Copy Title: Slope Failure Detection through Multi-temporal Lidar Data and Geotechnical Soils Analysis of the Deep-Seated Madrone Landslide, Coast Range, Oregon Author: Marshall, Michael Scott Year: 2016 Landslide hazard assessment of densely forested, remote, and difficult to access areas can be rapidly accomplished with airborne light detection and ranging (lidar) data. An evaluation of geomorphic change by lidar-derived digital elevation models (DEMs) coupled with geotechnical soils analysis, aerial photographs, ground measurements, precipitation data, and numerical modeling can provide valuable insight to the reactivation process of unstable landslides. A landslide was selected based on previous work by Mickleson (2011) and Burns et al. (2010) that identified the Madrone Landslide with significant volumetric changes. This study expands on previous work though an evaluation of the timing and causation of slope failure of the Madrone Landslide. The purpose of this study was to evaluate landslide morphology, precipitation data, historical aerial photographs, ground crack measurements, geotechnical properties of soil, numerical modeling, and elevation data (with multi-temporal lidar data), to determine the conditions associated with failure of the Madrone Landslide. To evaluate the processes involved and timing of slope failure events, a deep seated potentially unstable landslide, situated near the contact of Eocene sedimentary and volcanic rocks, was selected for a detailed analysis. The Madrone Landslide (45.298383/-123.338796) is located in Yamhill County, about 12 kilometers west of Carlton, Oregon. Site elevation ranges from 206 meters (m) North American Vertical Datum (NAVD-88) near the head scarp to 152 m at the toe. The landslide is composed of two parts, an upper more recent rotational slump landslide and a lower much older earth flow landslide. The upper slide has an area of 2,700 m2 with a head scarp of 5-7 m and a volume of 15,700 m3. The lower earth flow has an area of 2300 m2, a head scarp of 15 m, and a volume of 287,500 m3. Analysis of aerial photographs indicates the lower slide probably originated between 1956 and 1963. The landslide is located at a geologic unit contact of Eocene deep marine sedimentary rock and intrusive volcanic rock. The landslide was instrumented with 20 crack monitors established across ground cracks and measured periodically. Field measurements did not detect ground crack displacement over a 15 month period. Soil samples indicate the soil is an MH soil with a unit weight of 12 kN/m3 and residual friction angle of 28φ'r which were both used as input for slope stability modeling. Differential DEMs from lidar data were calculated to generate a DEM of Difference (DoD) raster to identify and quantify elevation changes. Historical aerial photograph review, differential lidar analysis, and precipitation data suggest the upper portion of the landslide failed as a result of the December 2007 storm.

  Citation × Citation Citation Abstract Copy Title: Technology Assessment of Waste Disposal Technologies for Tillamook County Author: Jiang, Jing, Jain, Abhishek, Lui, Jonathan, Garcia, Jorge, Limarta, Standley Year: 2015 We propose a two-level filter system to evaluate the potential for alternative waste management practices by conversion of locally-generated waste products such as animal mortality, manure, and wood waste into beneficial products such as energy in Tillamook county of Oregon. At the first level - coarse grained filter, three basic factors, technical readiness level (TRL), scaling capacity, and feedstock, are used to initially filter out the scanned technologies which can be potentially used in waste management. At the secondary level filter - fine grained filter, a numeric scoring model is created to evaluate technologies from the output of the first level filter. Since many factors will impact the selection of a technology, HDM (Hierarchical decision model) is used to score technologies. From technical, economic, social, and environmental perspectives, hierarchical multi-criteria factor structure is created, and constant-sum and pair-wise comparison are used to subjectively create the priority probability list about technologies. Composting technology, rendering technology, and hydrolysis are analyzed in detail. This developed alternative strategy will help to mitigate local liabilities, promote green jobs, develop clean energy, and reduce the carbon footprint in Tillamook County.
