Field and Laboratory Studies on the Development and Control of Soil Water Repellency of Sand Root Zone Mixes
Localized dry spots (LDS) associated with water repellent (i.e., hydrophobic) soils have detrimental effects on the survival, playability, and aesthetic value of creeping bentgrass (Agrostis palustris) used for golf course putting greens. The development of water-repellent soils, using molarity of …

Water repellency effects on liquid- and vapor-phase water exchange in soil and clay minerals
Drought conditions and wildfires can induce soil water repellency. Precipitation shifts are expected to exacerbate drought and wildfire in regions such as the southeastern United States, making it critical to understand how repellency affects water exchange processes in soil. The objectives of this …

Evaluating Five Years of Soil Hydrologic Response Following the 2009 Lockheed Fire in the Coastal Santa Cruz Mountains of California
… km<sup>2</sup> (7,660 acres) of the Scotts Creek watershed in August 2009. 4.5 km<sup>2</sup> (1,100 acres) of California Polytechnic State University’s educational and research facility at Swanton Pacific Ranch. The burned region presented an opportunity for studying the hydrologic response of …

Chemical and Physical Characterization of Pre- and Post-Fire Soils for Wildfires in the Western US and Laboratory Burns
… Wildfires modify physical and chemical soil properties and can cause the formation of post-fire Soil Water Repellency (SWR), which reduces water infiltration into the soil. This may induce cascading disasters including flooding, land and debris slides, and deterioration of water quality. …

Post-fire Response of Little Creek Watershed: Evaluation of Change in Sediment Production and Suspended Sediment Transport
<p>The Little Creek watershed was assessed to identify changes in event-based suspended sediment export and determine the factors contributing to sediment production the first year following the Lockheed Fire in 2009. The amount and volume of near-stream sediment sources were found to decrease, …

Post-Fire Sedimentation and the Risk to Sierra Nevada Water Supply
… Sierra Nevada region is crucial for the state’s water supply. Unfortunately, forested areas in important Sierra Nevada watersheds are being increasingly threatened by the growing risk of large, severe wildfires and in turn so are the water supplies that they support. This paper addresses how …

Hydraulic Properties Of Aggregated Oil Sand Material From The Athabasca Deposit
… sands mining-affected areas, is creation of a soil medium capable of supporting a target ecosystem. A considerable portion of these landscapes contain coarse-textured soils, which have poor water retention. Furthermore, many soils naturally contain oil sand, and little is known of its effects …

The influence of fungi upon soil structure and soil water relations
The investigation of soil structural stability and soil water processes was assessed through the application of laboratory investigations and a field based analysis. The impact of an arbuscular mycorrhizal (AM) fungal exudate glomalin (a glycoprotein), proposed to be hydrophobic was assessed for a …
