From atmospheric winds to fracture ventilation: Cause and effect

Creator:: Nachshon, Uri, Dragila, Maria, and Weisbrod, Noam
Abstract:: Vadose zone fractures and soil cracks exposed to the atmosphere have an impact on gas exchange processes at the Earth-atmosphere interface. In this study we explored and quantified the role of ground-surface winds on fracture ventilation. While the governing physical mechanisms that cause ventilation are relatively well understood, this is...

Infrared thermography of evaporative fluxes and dynamics of salt deposition on heterogeneous porous surfaces

Creator:: Nachshon, Uri, Shahraeeni, Ebrahim, Or, Dani, Dragila, Maria, and Weisbrod, Noam
Abstract:: Evaporation of saline solutions from porous media, common in arid areas, involves complex interactions between mass transport, energy exchange and phase transitions. We quantified evaporation of saline solutions from heterogeneous sand columns under constant hydraulic boundary conditions to focus on effects of salt precipitation on evaporation dynamics. Mass loss measurements...

Creator:: Gray, Myles, Johnson, Mark G., Dragila, Maria I., and Kleber, Markus
Abstract:: We assessed the effects of porosity and hydrophobicity on water uptake by biochars. Biochars were produced from two feedstocks (hazelnut shells and Douglas fir chips) at three production temperatures (370°C, 500°C, and 620°C). To distinguish the effects of porosity from the effects of hydrophobicity, we compared uptake of water to...

Creator:: VanHoosen, Amelia
Abstract:: There are a number of problems associated with urban expansion and as cities continue to grow the integration of green roofs can help to ease and offset many of them. This study uses a combination of moss and Sedum as vegetation for experimental green roof sections in order to test...

Microbes may induce soil water repellency through the production of aliphatic constituents as a response to desiccation

Creator:: Chilcote, Emma T.
Abstract:: Soil water repellency may be influenced by microbes whereby they produce aliphatic constituents (non-wetting materials) that coat the soil particles when they are subjected to desiccation stress.

Measurement Tool for Dynamics of Soil Cracks

Creator:: Stewart, Ryan D., Abou Najm, Majdi R., Rupp, David E., and Selker, John S.
Abstract:: Shrinkage cracks in soil function as a dominant control on the partitioning and distribution of moisture fluxes in the vadose zone. Their dynamics influence moisture balance and control water availability for runoff, deep infiltration, and near-surface storage. We present a new low-cost field instrument to monitor the temporal change in...
