Mathematical Investigation of Evaporation Synergy in Bi-Texture Soil Columns as a Function of Column Width

Creator:: Sumner, Michael J.
Abstract:: Evaporation synergy is a phenomenon that occurs between different classes of soil and allows for a greater amount/quantity of soil water evaporation. 20 of the 66 soil texture class combinations have been shown to exhibit evaporation synergy (Fisher, 2012), however the impact of column width on the functionality of this...

Effects of Initial Moisture and Surface Properties on Sorptivity of Coarse Soil and Sand

Creator:: Ambrowiak, Gloria M.
Abstract:: Many different models and mechanisms of water imbibition into soil have been described in the literature. Theoretical equations based on those models exist to predict how water will flow in porous media. These models can be useful, but have their weaknesses. Research on imbibition and infiltration into soils has mostly...

Evaporation from bare soil and soil cracks: a numeric study

Creator:: Graham, Christopher Brian
Abstract:: Evaporation from bare soil was investigated using a numeric model In one set of simulations, texture and evaporative demand were analyzed as they impacted short and long term evaporation. The effect of these factors on water redistribution was also analyzed. A second set of simulations was run to determine the...

Hydrological consequences of two native shrubs in semi-arid Senegal : patterns, processes, concepts and methods

Creator:: Kizito, Fred
Abstract:: Water availability is a critical limiting element in semi-arid ecosystem productivity and presents particular challenges in Sahelian countries such as Senegal. The landscapes are characterized by the presence of two common semi-arid shrubs (Piliostigma reticulatum and Guiera senegalensis), both of which may be important hydraulic regulators in these water-limited ecosystems....

Evaporation synergy in a bi-textured soil system

Creator:: Fisher, Arthur J.
Abstract:: Evaporation synergy is the phenomenon in which two porous medium textures that share a common vertical boundary experience a higher cumulative evaporation than either homogeneous texture can produce. Studies that have been conducted to date address this phenomenon in relatively fine and coarse sands but not in finer textured soils...

Plot-Scale Field Investigation : Characterizing Water Motion in Sandy Agricultural Soils

Creator:: Nolasco, Stephanie M.
Abstract:: Irrigated agricultural production in sandy soils presents several unique challenges to growers, including naturally high permeability, low native water retention, as well as high rates of water drainage losses and leaching of chemicals to the shallow aquifers. This study is an initial investigation into water motion in the sandy agricultural...

Solarization in the Pacific Northwest: A Mathematical Field Model for Accumulation of Linearized Mortality from Variable Intermittent Heat

Creator:: Hill, Brian C.
Abstract:: Soil solarization trials were conducted during the growing seasons of 2016-2018 with the purpose of determining if solarization was an effective pre-planting soil disinfestation technique for tree nurseries in the Pacific Northwest. A large data set was collected on soil properties and biological indicators from 5 interdisciplinary experiments. This thesis...

Genesis of iron oxides in unsaturated porous media

Creator:: Grover, Deeksha
Abstract:: The kinetics of physical and chemical processes controlling the precipitation of iron oxide minerals in unsaturated media were investigated in this study. The characteristic morphology, mineralogy, and chemistry of iron oxides were also explored. Laboratory column experiments using fine and coarse grades of silica sand were conducted to compare the...

Exploring mechanisms that drive the development of reversible soil hydrophobicity

Creator:: Woolverton, Priscilla B.
Abstract:: This study focuses on one widespread characteristic of poor soil quality: hydrophobic soil. Previous research has produced conclusive evidence to show that soil hydrophobicity is affected by soil organic matter (SOM) and soil water content (WC). Hydrophobicity that responds to changes in WC is a unique form of surface hydrophobicity...
