Abstract:
An alternative on-site wastewater treatment and disposal system (OSWTDS) consisting of a soil infiltrator with low pressure distribution was evaluated in a soil that was unsuitable for a conventional OSWTDS under current Commonwealth of Virginia Sewage Handling and Disposal Regulations, due to a shallow seasonally perched water table and low hydraulic conductivity. The absorption field consisted of two subsystems numbered as 1 and 2 with effluent design loading rates of 5.1 and 10.2 Lpd/m2, respectively (actual loading rates of 2.4 and 4.9 Lpd/m2, respectively). Soil matric potentials compared seasonally for each subsystem and indicated that both provided similar hydraulic performance. Background water quality was generally improved by subsurface movement through the absorption fields. A bacterial tracer was found in shallow (45.7 cm) and deep (213.4 cm) sampling wells within 24 h in the two subsystems (but in low numbers) over both summer and winter sampling periods. A viral tracer was detected within 48 h in both shallow and deep wells, but only in subsystem 2 in the winter. In evaluating denitrification potential, the addition of glucose to soil core samples did increase quantitatively, although not significantly, nitrous oxide production in each subsystem, at each depth, during each season. Overall, the performance of both subsystems was very similar. The soil infiltrator functioned very well, as designed for the site and soil limitations. It appears to be a potential alternative OSWTDS for use in problem soils.

Abstract:
This work investigates the material properties and production parameters of carbon infiltrated carbon nanotube structures (CI-CNT's). The impact of non homogeneous infiltration and the porosity of cross section regions, coupled with changes in designed geometry, in this case beam width, on the density and modulus of elasticity are compared. Three potential geometric models of beam cross section are proposed and evaluated. 3-point bending, SEM images, and numerical optimization are used to assess the validity of each model and the implications they have for future CI-CNT material applications. Carbon capping near exterior beam surfaces is observed and determined to be a contributing factor to variations in material properties correlated with changes in designed geometry and infiltration parameters (temperature, time, and hydrogen flow rate). Unexpected relationships between beam width and elastic modulus are partially explained by modeling the carbon-capped beams as C-shaped structural members consisting of a graphitic carbon shell of varying porosity and thickness and uninfiltrated carbon nanotube internal regions with a near negligible stiffness. Findings of previous works on the effects of infiltration parameters and carbon capping on materials properties are confirmed and expanded. Flange and web thickness and porosity of the graphitic carbon shell are identified as potential design parameters for pursuing tunable material properties in high precision geometry MEMS and compliant mechanism applications.

Os acidentes causados por aranhas do gênero Loxosceles representam importante problema de saúde pública no Brasil, sendo as principais espécies de importância médica L. intermedia, L. laeta e L. gaucho. O veneno dessas aranhas promove grave dermonecrose no local da picada, e menos comumente, doença sistêmica que pode ser fatal. O mecanismo de ação desse veneno não está completamente elucidado, trata-se de um processo multifatorial, que envolve a ação direta do veneno sobre os tecidos e a resposta do organismo a agressão causada pelo mesmo. Os camundongos constituem o modelo experimental menos susceptível ao desenvolvimento dos efeitos locais decorrentes do envenenamento por aranhas Loxosceles, dessa forma, sua utilização representa grande interesse clínico, cujo objetivo é desvendar tal mecanismo de proteção presente nestes animais. Este trabalho teve como objetivo caracterizar as atividades do veneno de Loxosceles intermedia, bem como avaliar as atividades in vivo deste veneno em camundongos. A manipulação e os procedimentos com os animais obedeceram aos princípios da CEUA/UFF (Comissão de Ética no Uso de Animais da Universidade Federal Fluminense). Foi demonstrado, in vitro, que o veneno de L. intermedia não apresenta atividade fosfolipásica A2, a atividade hialuronidásica e colágenásica foram dependente da concentração do veneno enquanto que a atividade proteolítica e esfingomielinásica foram observadas apenas em altas concentrações. Para descrever as ações do veneno de L. intermedia em camundongos, foi proposta a utilização de três diferentes linhagens: BALB/c, C57BL/6 e Suiço. A atividade edematogênica na pata dos camundongos inoculados com o veneno foi observada para as três linhagens testadas, sendo persistente por 24 horas, apenas para as linhagens BALB/c e C57BL/6. A análise histopatológica do local de inoculação intradérmica do veneno no abdomen apresentou diferenças relevantes, como, intensa congestão vascular em Suiços e presença de infiltrado inflamatório no local de inoculação na pele de BALB/c e C57BL/6. A partir destes achados, investigou-se a mobilização de células inflamatórias a partir da medula óssea, no baço e no sangue por citometria de fluxo, que demonstrou resposta imunológica inata típica, com aumento da cinética de células mieloides e linfócitos T citotóxicos para camundongos C57BL/6, e resposta tipicamente adquirida/humoral, com aumento preferencial de linfócitos B convencionais e T auxiliar para camundongos BALB/c. Desta forma, este trabalho demonstrou que modelos animais semelhantes podem apresentar diferentes respostas a inoculação deste veneno. A presença do infiltrado inflamatório no local de inoculação do veneno e a mobilização de células inflamatórias a partir da medula óssea, baço e sangue revelaram que diferentes linhagens de camundongos apresentam diferenças no tipo celular envolvido na resposta imunológica decorrente do envenenamento ou esta diferença pode estar relacionada ao tempo e velocidade da resposta em cada linhagem de camundongos. A partir destes resultados este trabalho sugere que camundongos da linhagem BALB/c podem ser utilizados como modelo para estudar a produção de IgM e IgG induzido pelo veneno, incluindo análise de citocinas, quimiocinas e mecanismos moleculares, por outro lado camundongos C57BL/6 podem ser utilizados para descrever a participação de células mielóides durante o envenenamento por aranhas do gênero Loxosceles
Accidents caused by spiders of the genus Loxosceles represent an important public health problem in Brazil, being the major species of medical importance L. intermedia, L. laeta and L. gaucho. The venom of these spiders induces an intense dermonecrosis at the bite site, and less commonly, systemic disease that can be fatal. The mechanism of action of this venom is not fully elucidated, it is a multifactorial process, which involves the direct action of the venom on the tissues and the body's response to aggression caused by it. The mice are an experimental model less susceptible to development the local effects of poisoning Loxosceles spiders. Thus, their use is great clinical interest, whose goal is to unravel the mechanism of this protection in these animals. This study aimed to characterize the activities of Loxosceles intermedia venom, as well as evaluating the in vivo activity of this venom in mice. Manipulation and procedures with animals obeyed the principles of CEUA / UFF (Ethics Committee on Animal Use Universidade Federal Fluminense). It has been shown in vitro that the venom of L. intermedia shows no phospholipase A2 activity and the hyaluronidase and collagenase were dependent on the concentration of the poison and while the proteolytic and sphingomyelinase activity were observed only at high concentrations. To describe the actions of the venom of L. intermedia in mice, it was proposed to use three different strains: BALB/c, C57BL/6 and Swiss. The activity in the paw edema of mice inoculated with the venom was observed for the three strains tested, being persistent for 24 hours, only for the strains BALB/c and C57BL/6. Histopathological analysis of the site of venom intradermal inoculation in the abdomen showed significant differences, as intense vascular congestion in Swiss and inflammatory infiltration at the site of inoculation in the skin of BALB/c and C57BL/6. From these findings, we investigated the mobilization of inflammatory cells from the bone marrow, spleen like effector organ, and migration into the blood by flow cytometry, which showed a typical innate immune response, with increased kinetics of myeloid cells and cytotoxic T lymphocytes to C57BL/6 mice, and response typically acquired / humoral, with a preferential increase of conventional B lymphocytes and T helper to BALB/c mice. Thus, this study demonstrated that similar animal models may have different responses to inoculation of this venom. The presence of the inflammatory infiltrate at the site of inoculation of the venom and the mobilization of inflammatory cells from the bone marrow, spleen and blood revealed that different strains of mice differ in cell type involved in the immune response resulting from poisoning and this difference can be related time and speed of response for each strain of mice. From these results, this study suggests that BALB/c mice can be used as a model to study the production of IgM and IgG induced by the venom, including analysis of cytokines, chemokines and molecular mechanisms, on the other hand C57BL/6 mice can be used to describe the involvement of myeloid cells during poisoning by spiders of the genus Loxosceles

Abstract:
Increased urbanization causes pervious greenfields to be converted to impervious areas increasing stormwater runoff. Most of the urban floods occur because existing drainage systems are unable to handle peak flows during rainfall events. During a storm event, flood runoff will carry contaminants to receiving waters such as rivers and creeks. Engineers and scientists have combined their knowledge to introduce innovative thinking to manage the quality of urban runoff and harvest stormwater for productive purposes. The introduction of pervious pavements addresses all the principles in Water Sensitive Urban Design. A pervious pavement is a load bearing pavement structure that is permeable to water. The pervious layer sits on the top of a reservoir storage layer. Pervious pavements reduce the flood peak as well as improve the quality of stormwater at source before it is transported to receiving waters or reused productively. To be accepted as a viable solution, understanding of the influence of design parameters on the infiltration rate (both from the bedding and the sub-base) as well as strength of the pavement requires to be established. The design of a particular pavement will need to be customized for different properties of sub layer materials present in different sites. In addition, the designs will have to meet local government stormwater discharge standards. The design of drainage systems underneath pervious pavements will need to be based on the permeability of the whole pervious system. The objectives of the research project are to: • Understand the factors influencing infiltration capacities and percolation rates through the pervious surface as well as the whole pavement structure including the bedding and the sub-base using a laboratory experimental setup. • Obtain relationships between rainfall intensity, infiltration rate and runoff quantity based on the sub-grade material using a computational model to assist the design of pervious pavements. A laboratory scale pavement was constructed to develop relationships between the surface runoff and the infiltration volume from a pervious pavement with an Eco-Pavement surface. 2 to 5mm crushed gravel and 5 to 20mm open graded gravel were chosen as the bedding and sub-base material. Initial tests such as dry and wet density, crushing values, hydraulic conductivity, California Bearing Ratio tests for aggregate material were conducted before designing and constructing the pavement model. A rainfall simulator with evenly spaced 24 sprays was set up above the pervious pavement surface. The thesis presents design aspects of the laboratory scale pavement and the tests carried out in designing the pavement and the experimental procedure. The Green and Ampt model parameters to calculate infiltration were obtained from the laboratory test results from aggregate properties. Runoff results obtained from rainfall simulator tests were compared with the Green and Ampt infiltration model results to demonstrate that the Green and Ampt parameters could be successfully calculated from aggregate properties. The final infiltration rate and the cumulative infiltration volume of water were independent of the rainfall intensity once the surface is saturated. The model parameters were shown to be insensitive to the final infiltration capacity and to the total amount of infiltrated water. The Green and Ampt infiltration parameters are the most important parameters in designing pervious pavements using the PCSWMMPP model. The PCSWMMPP model is a Canadian model built specially for designing pervious pavements. This is independent of the type of sub-grade (sand or clay) determining whether the water is diverted to the urban drainage system (clay sub-grade) or deep percolation into the groundwater system (sand sub-grade). The percolation parameter in Darcy's law is important only if the infiltrated water recharges the groundwater. However, this parameter is also insensitive to the final discharge through the subgrade to the groundwater. The study concludes by presenting the design characteristics influencing runoff from a pervious pavement depending on the rainfall intensity, pavement structure and sub-grade material and a step-by step actions to follow in the design.

Abstract:
Les métastases hépatiques compliquent l'évolution de 50% des cancers colorectaux (CCR). Plus de la moitié des patients présentent une récidive à distance avec métastases occultes pour lesquelles une chirurgie peut être réalisée dans moins de 20% des cas. L'ablation par radiofréquence (RFA) induit une réponse lymphocytaire T qui n'est pas évaluée après une intervention chirurgicale seule. L'immunothérapie combinée à la RFA pourrait potentialiser cet effet conduisant à une réponse tumorale à distance. Nous proposons une approche qui combine la RFA avec hydrogel thermoreversible libérant des agents immunomodulateurs (GMCSF et BCG) sur le site du traitementPremièrement, nous nous sommes intéressés à la sélection et à la caractérisation de la formulation optimale d’hydrogel par des techniques physicochimiques. Les propriétés de l'hydrogel ont été étudiées par rhéologie et des tests de muco-adhésion ont été mis en place. Le temps de résidence de l'hydrogel et de la protéine dans la zone tumorale a été démontré par imagerie optique. De plus, la cinétique de libération et l'intégrité du GMCSF encapsulé ont été déterminées. Ensuite, nous avons démontré l’efficacité de l’association de la RFA avec le dépôt local de l’hydrogel immunomodulatuer sur un modèle murin de cancer colorectal. En effet, nous avons observé une survie améliorée des animaux et régression complète des tumeurs distantes chez les animaux traités par la combinaison complète. Cette réponse est caractérisée par un niveau élevé de sécrétion de cytokines pro-inflammatoires par les cellules T CD4 et TCD8 et une augmentation de l’infiltrat lymphocytaire dans les tumeurs. Ceci a permis d'envisager une association avec l'immunothérapie anti-PD1 dans le traitement de macrométastases échappant au traitement combiné RFA avec l’hydrogel immunomodulateur. En effet, l’immunothérapie dans le traitement du cancer colorectal métastatique présente une efficacité limitée chez les patients. Notre travail propose a démontré que l’efficacité de l’immunomodulation locale dans l’amélioration des réponses immunitaires dans le cancer colorectal. Ces résultats permettent de reconsidérer l’utilisation de l’immunothérapie chez les patients atteints de CCR métastatique non MSI
Liver metastases complicate the progression of 50% of colorectal cancers (CRC). More than half of the patients have recurrent remissions with occult metastases for which surgery can be performed in less than 20% of cases. Radiofrequency ablation (RFA) induces a T lymphocyte response that is not observed after surgery alone. Combined immunotherapy with RFA may potentiate this effect leading to a distant tumor response. We propose an approach that combines RFA with thermoreversible hydrogel releasing immunomodulatory agents (GMCSF and BCG) at the treatment site.First, we focused on the selection and characterization of the optimal hydrogel formulation by physicochemical techniques. The properties of the hydrogel were studied by rheology and mucoadhesion tests were set up. The residence time of the hydrogel and the protein in the tumor zone was demonstrated by optical imaging. In addition, the release kinetics and integrity of the encapsulated GMCSF were determined. Then, we demonstrated the effectiveness of the combination of RFA with the local deposition of the immunomodulatory hydrogel on a mouse model of colorectal cancer. Indeed, we observed improved survival of animals and complete regression of distant tumors the complete treatment group. This response is characterized by a high level of pro-inflammatory cytokine secreted by CD4 and TCD8 T cells and an increase Lymphocytes infiltrating tumors. The immune escape of large lesions was reversed by association with anti-PD1 immunotherapy Indeed, immunotherapy in the treatment of metastatic colorectal cancer has limited efficacy in patients. Our work has demonstrated the effectiveness of local immunomodulation in improving immune responses in colorectal cancer. These results make it possible to reconsider the use of immunotherapy in patients with non-MSI metastatic CRC

Abstract:
In thermal Molten Salt Reactors, the nuclear graphite core is in direct contact with the molten salt coolant. Due to the porous nature of nuclear graphite, the molten salt may infiltrate the nuclear graphite, which may affect the mechanical strength and irradiation behavior of the nuclear graphite. In order to evaluate the infiltration behavior of molten salt in nuclear graphite, both FLiNaK and FLiBe salts were used to infiltrate two typical nuclear graphite grades: IG110 and NBG18. The pressure dependence of the infiltration weight gain ratio was measured. The influence of molten salt infiltration on the thermal properties of these two graphite grades, such as their thermal expansion behavior and thermal conductivity, was also measured. The mechanical strength of the FLiNaK-infiltrated graphite was measured at room temperature and elevated temperature, and showed that the mechanical strength of the nuclear graphite was enhanced at room temperature and weakened at elevated temperature by molten salt infiltration. Finally, the thermal expansion coefficient and the fracture surface analysis measured after FLiNaK infiltration indicated that the stress induced by molten salt infiltration could be one of the reasons for the graphite property changes.

Abstract:
Abstract The most common way of transportation for refined oil is long-distance pipeline. Pipeline accidents occur frequently due to corrosion, equipment failure, external forces destruction. Aiming at predicting the contaminated area in soil caused by products pipeline accidents, this experimental study was conducted to examine the relationship between the light non-aqueous phase liquids (LNAPL) accumulative infiltrate volume and the time of infiltration process in homogeneous and layered soils. The soil’s hydraulic parameters were obtained by basic experiments and RETC software. Compared with traditional infiltration mathematical model, Green-Ampt model is the most common mathematical model to calculate the infiltration process in the unsaturated soil. In this study, a modified Green-Ampt model was developed to describe water and diesel infiltration through a 100-cm-long and layered soil column. In the modified Green-Ampt model, an infiltration reduction ratio was introduced to describe the effect of the hydraulic conductivity of the layered position. To evaluate the proposed method in the effect of the layers position infiltration permeability, eight constant water head layered column infiltration experiment were conducted to record the different infiltration fluid and different constant water head infiltration process. Compared the experiment results with traditional mathematical traditional Green-Ampt model (average R2 = 0.976) and Hydrus-1D software (average R2 = 0.988) The modified Green-Ampt model had relatively higher precision in accumulative infiltrate volume (average R2 = 0.992) and the wetting front velocity in infiltration process (average R2 = 0.997). Thus, the modified mathematical model was applied an effective upscaling scheme in layered formations. The experimental result also demonstrated that soil layering affected the infiltration process. With the increase of soil depth and density, the infiltration speed of the layered soil column decreased. Additionally, the infiltrate speed of wetting front decreases slowly at the layered surface. The experiment’s fitting results showed that the modified mathematical model about infiltrate time and liquid contaminant accumulative infiltrate volume, wetting front infiltrate velocity can highly effective approach to simulate water and light non-aqueous phase liquids (LNAPL) infiltration process in layered soils.

Abstract:
Selective Laser Sintering (SLS) is tooless, computer-controlled layerwise additive manufacturing using a laser and a powder bed. The scanning laser locally melts the surface of a powder bed selectively, followed by deposition of a fresh layer of powder and repetition of the process. SLS has been developed for plastic powder. Creation of non-metallics and metal parts is more challenging. One approach is to mix the master powder with a transient binder. SLS melts the binder which wets the master powder, creating a green part. Subsequent post-processing is required to either remove the binder or convert it to a usable form. The last step is infiltration with a molten substance. Fundamentals of infiltration theory will be reviewed. A study of dimensional changes associated with various stages of processing reveals that overall linear dimensions vary less than one percent compared to the computer solid model. Several examples demonstrating the utility of an infiltration approach to freeform fabrication will be presented. These include silicon carbide with a phenolic binder, infiltrated with silicon; graphite with a phenolic binder infiltrated with epoxy; and tool steel with a proprietary low-ash binder infiltrated with cast iron.

Abstract:
Infiltration methods for improving lanthanum strontium cobalt ferrite (LSCF) cathode performance through catalyst surface modification were evaluated at the U.S. Department of Energy, National Energy Technology Laboratory. Infiltration of mixed conductors into LSCF cathodes of solid oxide fuel cells promises a low cost method of improving oxygen exchange and performance in these materials at lower temperatures. LSCF cathodes on Nickel-Yttria Stabilized Zirconia (Ni-YSZ) anode supported cells were infiltrated with strontium-doped lanthanum zirconate (LSZ) pyrochlores using two methods. An aqueous solution of nitrate salts was vacuum infiltrated into the cathodes of anode supported button cells, and the cells were heated to form the pyrochlore phase in-situ. This was compared to the efficacy of infiltrating a suspension of pyrochlore nanoparticles. Different dispersants were used to prepare the nanoparticle suspensions at varying concentrations and pH levels, and the results are compared.

Abstract:
Three-dimensional interconnected microfluidic channels fabricated by the direct-write method were infiltrated with SWCNT/epoxy nanocomposites under high shear flow to mechanically characterize the effect of single-walled carbon nanotubes (SWCNTs) spatial orientation in thermosetting-matrix nanocomposites. The micron-size fugitive ink filaments were deposited layer by layer in order to form a scaffold followed by its encapsulation by an epoxy resin. Three-dimensional interconnected microfluidic channels were then obtained by heat curing the encapsulated epoxy followed by fugitive ink removal by liquefying it at high temperature under vacuum. To debundle the Laser-ablated single-walled carbon nanotubes (La-SWNTs), nitric acid treatment following introduction of protoporphyrin IX as surfactant were done to prevent reclustering of the CNTs after separation. La-SWNTs were then mixed with ultraviolet-curable epoxy using a three-roll mill machine to achieve a well-dispersed nanocomposite. The nanocomposites were then infiltrated within the empty channels at high pressures to induce shear. High shear flow infiltration of nanocomposites will cause the CNTs to be aligned in the direction of the channels where an increase in shear leads to an increase in CNT alignments. Finally, in order to mechanically investigate the effectiveness of the infiltration technique and the orientation of SWCNTs, tensile and three-point bending tests were done.

Full text
Abstract:
Thermal barrier coating (TBC) spallation on power generation combustors was compared with TBC spallation observed both in military turboshaft engines, and in commercial turboprop engines. In each case, irrespective of operating conditions or geographic location, spallation was linked to the presence and infiltration of high temperature molten phases of similar composition. Electron microprobe analysis found that, from all the possible oxides available in the external environment, only CaO, MgO, Al2O3 and SiO2 (CMAS) are incorporated in the molten phase that infiltrates the TBC microstructure. Iron and nickel oxides from turbine components and zirconia and yttria from the TBC were also found in varying amounts in the molten phase. Melting of environmental deposits in conjunction with infiltration was found to result in: densification of the TBC, an increase in its Young’s modulus and an increase in the room temperature compressive stress in the TBC. Delamination of the TBC during thermal cycling is, thereby, attributed to changes in the mechanical properties and associated changes in the stress state of the coating due to infiltration of the environmental deposit.

Abstract:
Abstract Binder Jetting Process involves binding layers of powder material through selective deposition of a liquid binder. Binder jetting is a fast and relatively inexpensive process which does not require a high-powered energy source for printing purpose. Additionally, the binder jetting process is capable of producing parts with extreme complexities without using any support structures. These characteristics make binder jetting an ideal choice for several applications including aerospace, biomedical, energy, and several other industries. However, a significant limitation of binder jetting process is its inability to produce printed parts with full density thereby resulting in highly porous structures. A possible solution to overcome the porosity problems is to infiltrate the printed structures with low-melting nanoparticles. The infiltrating nanoparticles help fill up the voids to densify the printed parts and also aids in the sintering of the printed green parts. In addition to increasing the density, the nanoparticle infiltration also helps improve the mechanical, thermal and electrical properties of the printed part along with bringing multi-functionality aspect. Currently, there is a lack of clarity of the nanoparticle infiltration process performed to improve the quality of parts fabricated through binder jetting. This research employs Molecular Dynamics simulation techniques to investigate the nanoparticle infiltration during binder jetting additive manufacturing process. The simulation is performed at different operating temperatures of 1400 K, 1500 K, and 1600 K. The study found that the infiltration process is significantly affected by the operating temperature. The infiltration height is found to be highest at the operating temperature of 1600 K while the porosity reduction is found to be maximum at 1500 K. The infiltration kinetics is affected by the cohesion of the nanoparticles causing blockage of channels at higher operating temperatures. The simulation model is validated by comparing with the Lucas-Washburn infiltration model. It is seen that the simulation model deviates from the theoretical prediction suggesting that multiple mechanisms are driving the infiltration process at the nanoscale.

Abstract:
High-temperature mechanical properties and tension-tension fatigue of three SiC/SiC ceramic composites are discussed. Effects of steam on high-temperature fatigue are evaluated. The three composites consist of a SiC matrix reinforced with SiC (Hi-Nicalon™) fibers. Composite 1 was processed by chemical vapor infiltration (CVI) of SiC into fiber preforms coated with BN. Composite 2 had an oxidation inhibited matrix consisting of alternating SiC and B4C layers and was processed by CVI. Fiber preforms were coated with pyrolytic carbon with B4C overlay. Composite 3 had a melt-infiltrated (MI) matrix consolidated by combining CVI-SiC with SiC particulate slurry and molten Si infiltration. Fiber preforms were coated with BN. Tension-tension fatigue was investigated at 1200°C in air and in steam. Steam significantly degraded the fatigue performance of composites 1 and 3, but had little influence on the fatigue performance of composite 2. Composite microstructure, as well as damage and failure mechanisms were investigated.

Abstract:
Soil water wettability or water repellency is a phenomenon that can affect infiltration and, ultimately, runoff. Thus, there is a need to develop a model that can quantitatively capture the influence of water repellency on infiltration in a physically meaningful way and within the framework of existing infiltration theory. The analytical model developed in this study relates soil sorptivity (an infiltration parameter) with contact angle (a direct measure of water repellency) for variably saturated media. The model was validated with laboratory experiments using a silica sand of known properties treated to produce controlled degrees of water repellency. The measured contact angle and sorptivity values closely matched the model‐predicted values. Further, the relationship between the frequently used water drop penetration time test (used to assess water repellency) and sorptivity was illustrated. Finally, the direct impact of water repellency on saturated hydraulic conductivity was investigated due to its role in infiltration equations and to shed light on inconsistent field observations. It was found that water repellency had minimal effect on the saturated hydraulic conductivity of structureless sand. A quantitative model for infiltration incorporating the effect of water repellency is particularly important for post‐fire hydrologic modeling of burned areas exhibiting water repellent soils.
