To explain the dynamic behavior of the matric potential at the wetting front of gravity
driven fingers, we take into account the pressure across the interface that is not continuous
and depends on the radius of the meniscus, which is a function of pore size and the dynamic
contact angle...

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...
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...
Accurate measurement of the amount and timing of surface runoff at multiple scales is needed to understand fundamental hydrological processes. At the plot-scale (i.e., length scales on the order of 1 to 10 m) current methods for direct measurement of runoff either store the water in a collection vessel, which...

The hierarchical organization of aggregates in soil is responsible for the presence of inter and intra-aggregate pores. This research aimed to investigate effects of soil surface liming, considering lime rates of 0, 10 and 15 t ha(-1), on the intra-aggregate porous system of soil aggregates with equivalent diameters of 2-4...
Irrigation experiments on 12 instrumented field plots were used to assess the impact of dynamic soil crack networks on
infiltration and run-off. During applications of intensity similar to a heavy rainstorm, water was seen being preferentially
delivered within the soil profile. However, run-off was not observed until soil water content...
This thesis explores the mechanical properties of hemp fiber reinforced polylactic acid (PLA) composites. Fused filament fabrication (FFF) was used to compare the performance of three different weight percentages of hemp fiber reinforced PLA against PLA and acrylonitrile butadiene styrene (ABS). It was found that as the weight percentage of...
