Impact Of Bubble Baths On Stainless Steel Sphere Water Entry, Wesley Robinson
Impact Of Bubble Baths On Stainless Steel Sphere Water Entry, Wesley Robinson
Physics Capstone Projects
Soap Bubbles on the water surface would seem to be an intuitive means for splash suppression, but their presence appears to be a double edged sword. We present on the water entry of hydrophilic spheres where the liquid surface is augmented by the presence of a bubble layer, similar to a bubble bath. While the presence of a bubble layer can diminish splashing upon impact at low Weber numbers, it also induces cavity formation at speeds below the critical velocity. The formation of a cavity generally results in larger Worthington jets and thus, larger amounts of ejected liquid. Bubble layers …
Sound Impacts: Building An Impact Metrics Portal For Tracking Collective Positive Impacts Of Restoration And Green Infrastructure Across The Puget Sound, Aaron Clark
Salish Sea Ecosystem Conference
SoundImpacts.org is a pilot of a regional scale, multi-user impact metrics portal. Entities engaged in restoration and positive impact environmental projects like green infrastructure (including rain gardens, tree planting, green roofs, depaving etc.) are highly dispersed, "siloed" and generally don't share data with each other and in fact rarely share the impacts of their work to their own communities beyond the funders who paid for the specific project. Sound Impacts addresses the tandem needs of 1. positive impact practitioners (e.g. NGO's, tribes, government agencies, communities) to collect and track their own impacts to better share that with their audiences and …
Quantifying Permafrost Extent, Condition, And Degradation Rates At Department Of Defense Installations In The Arctic, Christopher A.J. Edlund
Quantifying Permafrost Extent, Condition, And Degradation Rates At Department Of Defense Installations In The Arctic, Christopher A.J. Edlund
Theses and Dissertations
The DoD is planning over $500M in military construction on Eielson Air Force Base (AFB) within the next three years. This construction program will expand the footprint of facilities and change parts of the storm water management scheme, which may have second order effects on the underlying permafrost layer. These changes in permafrost will drive engineering decision making at local and regional levels, and help shape the overall strategy for military readiness in the Arctic. Little site-specific knowledge exists on the human caused effects to permafrost at this location. In 2016, the permafrost degradation rates at Eielson AFB were modeled …
Future Nuisance Flooding In Norfolk, Va, From Astronomical Tides And Annual To Decadal Internal Climate Variability, A. G. Burgos, B. D. Hamlington, P. R. Thompson, R. D. Ray
Future Nuisance Flooding In Norfolk, Va, From Astronomical Tides And Annual To Decadal Internal Climate Variability, A. G. Burgos, B. D. Hamlington, P. R. Thompson, R. D. Ray
OES Faculty Publications
Increasing sea level rise will lead to more instances of nuisance flooding along the Virginia coastline in the coming decades, causing road closures and deteriorating infrastructure. These minor flood events can be caused by astronomical tides alone, in addition to internal climate variability on annual to decadal timescales. An assessment of nuisance flooding from these two effects is presented up until the year 2050 for Norfolk, Virginia. The analysis of water levels indicates that nuisance flooding from tides alone in conjunction with a medium-high sea level scenario will result in flooding beginning in 2030 with frequency increasing thereafter. The addition …
