In 2015, the U.S National Institute of Standards and Technology (NIST) funded Center Excellence for Risk-Based Community Resilience Planning (CoE), a fourteen university-based consortium almost 100 collaborators, including faculty, students, post-doctoral scholars, NIST researchers. This paper highlights scientific theory behind state-of-the-art cloud platform being developed by CoE - Interdisciplinary Networked Modeling Environment (IN-CORE). IN-CORE enables communities, consultants,...
Highway bridges are one of the most vulnerable constituents transportation networks when exposed to or more natural hazards, such as earthquakes, hurricanes, tsunamis, and riverine floods. To facilitate enhance prehazard posthazard event mitigation emergency response strategies systems entire communities, probabilistic risk resilience assessment methodologies have attracted increased attention recently. In this context, fragility restoration models for highway subjected a range hazards...
Vegetation at the aquatic-terrestrial interface can alter landscape features through its growth and interactions with sediment fluids. Even similar species may impart different effects due to variation in their feedbacks environment. Consequently, replacement of one engineering by another cause significant change physical Here we investigate species-specific ecological mechanisms influencing geomorphology U.S. Pacific Northwest coastal dunes. Over last century, this system changed from open,...
Tsunami debris can place large demands on the structures it impacts. The types of potential and impact forces they generate are not well understood, relatively little consideration is taken for risk tsunami strikes during structural design. A procedure outlined to assess site-specific its significance structures. involves a categorization based fundamental characteristics. It includes an assessment ability likelihood transport, as constrained by topography constructed environment. Data from...
To gain a better understanding of the wave forces that led to failure numerous causeway-type coastal highway bridges along U.S. Gulf coast, series experiments was conducted on realistic, 1:5 scale reinforced concrete bridge superstructure. The experimental setup is unique compared other wave-in-deck studies in stiffness horizontal support system can be varied represent different dynamic properties system. specimen subjected wide range regular and random conditions at multiple water levels....
Tsunamis affect coastal regions around the world, resulting in fatalities and catastrophic damage to communities. Fragility functions form basis of most risk resilience analyses at individual structure level, thereby allowing physical infrastructure components be included community level. For tsunami loading, vast majority fragilities that have been developed are based on postevent observations field, which usually specific site event. In this paper, a methodology generate physics-based...
A probabilistic framework is presented for the development of physics and simulation-based parametrized tsunami fragility functions structures accounting structural member failures. The proposed general accounts material geometric sources uncertainty makes use nonlinear finite-element models first-order second-moment (FOSM) reliability method. application illustrated with an example reinforced concrete moment frame building designed to recent United States codes. Results indicate that...
Abstract To understand the interaction between wave‐breaking induced turbulent coherent structures and suspended sediment transport, we report a Large‐Eddy Simulation (LES) study of processes over near‐prototype scale barred beach. The numerical model is implemented using open‐source CFD toolbox, OpenFOAM ® , in which incompressible three‐dimensional filtered Navier‐Stokes equations for water air phases are solved with finite volume scheme. A fluid (VOF) method used to capture evolution...
This study investigates the potential of a Rhizophora mangrove forest moderate cross-shore thickness to attenuate wave heights using an idealized prototype-scale physical model constructed in 104 m long flume. An 18 transect red based on trunk-prop root system was Two cases with densities 0.75 and 0.375 stems/m 2 third baseline case no mangroves were considered. LiDAR used quantify projected area per unit height estimate effective diameter system. The methodology accurate within 2% known...

Laboratory measurements of the instantaneous horizontal and vertical turbulent velocities, u ′ w ′, induced by regular waves spilling on a rough, impermeable slope were analyzed to elucidate nature turbulence generated in bottom boundary layer wave breaking. The analyses focused events such as absolute shear stress |τ′| = |− ′| kinetic energy k ( 2 + )/2. Below trough level inside surf zone, velocity records showed intense, intermittent that did not occur with passing each wave, quantities...
