In-situ measurements of energetic depth-limited wave loading

چکیده
An extensive database of in situ measurements wave impact pressure on the wall a composite breakwater and associated explanatory variables (i.e., waves, wind, water level) was collected particularly high-energy environment. Due to bottom profile, which includes wide mound concrete blocks with seaward edge that rises Lowest Astronomical Tide level over large distance, most waves break before reaching monitored barrier, making data set representative depth-limited loading. Maximum is consistently found at sensor position closest mean free surface, statistically, decrease maximum altitude observed. Nevertheless, also shows variety vertical profiles pressure. A detailed analysis signal there are two classes values. The first mostly observed during stormy conditions relatively slow variations time fairly uniform spatial distribution. second class exhibits very limited peaks space often moderate sea states high levels. signals for each agree well prediction PROVERB classification based dimensions, level, parameters. Our dataset existence impacts simultaneous rise time, extends range values impulse already reported in-situ from 31000 Pa.s 100000 Pa.s. For strong show regular upward propagation, peak propagation velocity estimated remain below 20 m/s. Finally, we performed statistical relate number variables, including offshore parameters, wind multiple linear regression model created confirms dominant influence height negligible maxima. other parameters still significant but secondary importance. upper bound 99% interval predicts given good confidence an encouraging result.

non-invasive continuous surface wave measurements for in situ damping ratio profiling of soils
local site conditions have a strong effect on ground response during earthquakes. two important soil parameters that control the amplification effects of seismic motions by a soil column are the soil hysteretic damping ratio and shear wave velocity. this paper presents the results of in situ damping ratio measurements performed using continuous surface wave attenuation data at a site in semnan ...
متن کاملWind Wave Behavior in Fetch and Depth Limited Estuaries
Wetland dominated estuaries serve as one of the most productive natural ecosystems through their ecological, economic and cultural services, such as nursery grounds for fisheries, nutrient sequestration, and ecotourism. The ongoing deterioration of wetland ecosystems in many shallow estuaries raises concerns about the contributing erosive processes and their roles in restraining coastal restora...
متن کاملUsing Noise and Fluctuations for In Situ Measurements of Nitrogen Diffusion Depth
In manufacturing processes involving diffusion (of C, N, S, etc.), the evolution of the layer depth is of the utmost importance: the success of the entire process depends on this parameter. Currently, nitriding is typically either calibrated using a "post process" method or controlled via indirect measurements (H2, O2, H2O + CO2). In the absence of "in situ" monitoring, any variation in the pro...
متن کاملIn situ hydrogen loading on zirconium powder
For the first time, various hydride phases in a zirconium-hydrogen system have been prepared in a high-energy synchrotron X-ray radiation beamline and their transformation behaviour has been studied in situ. First, the formation and dissolution of hydrides in commercially pure zirconium powder were monitored in real time during hydrogenation and dehydrogenation, then whole pattern crystal struc...
