Abstract. On 23 August 2017 a Category 3 hurricane, Typhoon Hato, struck southern China. Among the hardest hit cities, Macau experienced worst flooding since 1925. In this paper, we present high-resolution survey map recording inundation depths and distances at 278 sites in Macau. We show that one-half of Peninsula was inundated, with extent largely confined by hilly topography. The Inner Harbor area suffered most, maximum depth 3.1 m coast. Using combination numerical models, simulate...
The effects of air inlet temperature on the flame structures and local extinctions n-decane swirl spray flames at constant flow velocity were clarified by using simultaneous planar laser induced fluorescence measurements OH CH2O. Results show that blowoff limit decreases 48% as increases from 298 to 473 K. [CH2O] × [OH] overlap are mainly distributed near shear layer, while a small amount formaldehyde is also observed in outer recirculation zone (ORZ), corresponding low-temperature...
In this article, we demonstrate that the normalized runup heights, R/H0 (R = height; H0 incident wave height), for breaking solitary and periodic waves can be characterized by a single dimensionless parameter, called surf which is defined theoretical wave-breaking criterion. Existing laboratory data both were collected are summarized in article. Breaking include surging, plunging, spilling breakers. To enhance range of parameters waves, set new experiments was carried out large-scale flume...
ABSTRACT Although students in Introductory Information Systems courses are taught new technology concepts, the complexity and constantly changing nature of these technologies makes it challenging to deliver concepts effectively. Aiming improve students’ learning experiences, this research utilized five phases design science methodology develop an experiment solve a real‐world problem, then implemented undergraduate classroom. As part their classwork, participated as subjects testing...
Protection of nearshore area by means artificial structure is an important issue for coastal engineering community. In this study, we aim to investigate wave hydrodynamics and hydrodynamic performance due solitary waves interacting with double submerged barriers. Double barriers, put bottom-mounted vertically on the flat seafloor also paralleled each other, are considered as a absorber. New experiments carried out provide measured data model validation. Numerical simulations performed using...
An experimental results on the spatio-temporal variation of velocity field and vortex structure, generated from separated boundary layers offshore side still-water shoreline, during run-down process non-breaking solitary waves over a 1:3 sloping beach are presented. Three having incident wave-height to water-depth ratios (H0/h0) 0.363, 0.263, 0.171 were in wave flume. Two flow visualization techniques high-speed particle image velocimetry employed. The primary topics new findings are: (1)...
In this article, the interaction of solitary waves and a submerged slotted barrier is investigated in which consists three impermeable elements its porosity can be determined by distance between two neighboring elements. A new experiment conducted to measure free surface elevation, velocity, turbulent kinetic energy. Numerical simulation performed using two-dimensional model based on Reynolds-Averaged Navier-Stokes equations non-linear k-ɛ turbulence model. detailed flow pattern illustrated...
The entrained air and turbulence characteristics under a breaking solitary wave on 1:20 sloping beach are investigated through laboratory measurement.

Results show that...
We study the interactions between a non-breaking solitary wave and submerged permeable breakwater experimentally numerically. The particle image velocimetry (PIV) technique was employed to measure instantaneous free surface displacements velocity fields in vicinity of porous media. media, consisted uniform glass-made spheres, mounted on seafloor. Quantitative mean properties were obtained by ensemble averaging 30 repeated measurements. In addition, two different numerical considerations are...

Wave interactions with vertical and sloping seawalls are indeed complicated, especially for the impacts due to breaking waves, which unsteady, turbulent multi-phase. Available studies successfully measured impact pressure waves acting on seawalls, whereas associated flow velocity turbulence characteristic received limited attention, indicating that momentum of such violent free-surface flows cannot be determined. In this study, new experiments were carried out in a laboratory-scale wave...
