Using Terrestrial LiDAR to Monitor Erosion within the Gold Basin Landslide Complex, Verlot, WA
In 2014 the United States Forest Service closed the Gold Basin Campground of western Washington in an effort to protect the public from unstable hillslopes directly adjacent to the campground. The Gold Basin Landslide Complex (GBLC) is actively eroding via block fall, dry ravel, and debris flows, which contribute sediment ...
Calculating the Uncertainty of a Structure from Motion (SfM) Model, Cadman Quarry, Monroe, Washington
Structure from Motion (SfM) is a new form of photogrammetry that automates the rendering of georeferenced 3D models of objects using digital photographs and independently surveyed Ground Control Points (GCPs). This project seeks to quantify the error found in Digital Elevation Models (DEMs) produced using SfM. I modeled a ...
Observations of Joints Present in the Lawton Clay Member of the Vashon Stade, Exposed at a Coastal Bluff in Discovery Park, Seattle, Washington
The southwest-facing coastal bluff present at Discovery Park, Seattle, Washington, displays distinctive joints throughout the exposed Lawton Clay Member. Exhibiting a characteristic local stratigraphy of permeable advance outwash over the impermeable proglacial lacustrine clay, this bluff is located in an area of Seattle ...
A comparative Analysis of Grain Size distributions and Cross Sections using an Oblique Photoset on the Nisqually Riverbed Adjacent to Longmire In Mount Rainier National Park
Collecting cobble counts and gathering cross sections out in the field can be a tedious and time consuming process. An attempt was made at expediting this process using structure from motion technology to create an orthophoto and a digital surface model of the Nisqually riverbed adjacent to Longmire in Mount Rainier National ...
Rockfall Reconnaissance and Stability Assessment: Frenchman Coulee, WA
The Sunshine Wall, a 30-meter tall outcrop of Columbia River Flood Basalt, is a popular climbing wall within Frenchman Coulee, located in central Washington. This study investigates the stability of the columnar basalt that makes up the wall, to educate climbers on how this slope fails and provide qualitative estimates of how ...
Using the Rockfall Activity Index to assess the impact of scaling on rock fall activity at Glitter Gulch, Alaska
This research examines terrestrial-laser scan data on a road cut in the Glitter Gulch area of Alaska, immediately preceding and following a slope stabilization project, noting changes in rock fall and comparing the work done during excavation to the hazardous areas identified through the "Rockfall Activity Index (RAI) model ...
