Abstract:: Wildfires can affect soil physical properties, resulting in changes in infiltration, hillslope runoff, groundwater recharge, and sediment and dissolved nutrients to streams. In November 2016, the Chimney Tops 2 Fire burned 4,617 ha of Appalachian hardwood forest in eastern Tennessee. A portion of the fire burned through a National Ecological...

Abstract:: Vineyards in Oregon’s Willamette Valley are predominately planted to perennial grass cover in the alleyways of vineyards. This grass cover is grown to increase worker and equipment traction, as well as reduce erosion and manage vine vegetative vigor. However, with increasing frequencies of drought and warming temperatures, the use of...

Creator:: Cole, Ryan P.
Abstract:: The extent and severity of wildfires in forested regions are increasing throughout many regions on the planet, including western North America. High-severity wildfires directly affect soils and vegetation by altering soil hydraulic properties, reducing soil organic matter, exporting carbon and nitrogen, and killing trees and understory vegetation. These impacts can...

Abstract:: The purpose of this study was to investigate the effects of wildfire on soil hydraulic properties of forested hillslopes. The study site was located within the Stouts Creek wildfire, which burned approximately 10,705 ha of forest in southwestern Oregon in summer 2015. Three soil hydraulic properties (soil moisture, unsaturated hydraulic...

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...

Abstract:: Understanding the mechanisms controlling colloid transport and deposition in the vadose zone is an important step in protecting our water resources. Colloid transport in unsaturated porous media was studied using X-Ray Microtomography (XMT), which is a non-destructive imaging technique that provides three-dimensional images at a resolution on the order of...

Abstract:: Deeply weathered soils in tropical rainforests and savannas are classified as Ferralsols according to the World References Bases for Soil Resources (WRB). Ferralsols are most nearly akin to the Oxisols order defined in the US Soil Taxonomy. The acidity, low cation exchange capacity, and strong phosphorus retention by the oxidic...
