Comparing Rusle Ls Calculation Methods Across Varying Dem Resolutions, Amanda Moody
Comparing Rusle Ls Calculation Methods Across Varying Dem Resolutions, Amanda Moody
All Master's Theses
Soil erosion is a global problem that reduces land productivity and causes environmental degradation. Soil erosion models, such as the Revised Universal Soil Loss Equation (RUSLE), are used to estimate the severity and distribution of erosion. The topographic factor (LS), which combines slope length and angle, is an important part of RUSLE. This work compared two methods of L calculation, the grid cumulation (GC) and the contributing area (CA) methods, and two methods of S calculation, the neighborhood (NBR) and maximum downhill slope (MDS) methods. These were compared across digital elevation models (DEMs) of 1, 5, 10, and 30m resolutions. …
Monitoring Reduction Efforts For Pm2.5 In Ellensburg,Wa Using Community-Based Social Marketing To Examine Behavioral Change, Kelsey Gibbs
Monitoring Reduction Efforts For Pm2.5 In Ellensburg,Wa Using Community-Based Social Marketing To Examine Behavioral Change, Kelsey Gibbs
All Master's Theses
In 2011, Ellensburg, Washington was labeled by the Washington Department of Ecology as being vulnerable for violating National Ambient Air Quality Standards for particulate pollution (PM2.5). In the Kittitas Basin, winter-time frequent air inversions and stagnant air events trap pollution near the ground, elevating pollutant concentrations during winter months. Wood smoke from household burning has been identified by mobile PM2.5 monitoring completed in 2015 as the primary source of PM2.5. This research utilizes community-based social marketing techniques to encourage behavioral change for wood burning in a targeted neighborhood in Ellensburg. Residents of the target neighborhood …
A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
All Master's Theses
Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …
