The low-lying reef islands distributed in the tropical and subtropical coastal regions are highly vulnerable to devastating damages of surges waves during severe weather events. Over past two decades, extreme have caused tremendous loss regions. Previous research has focused on wave hydrodynamics tsunami waves, as well regular irregular fringing reefs. complex reefs rarely studied. By applying ...

[1] The devastating 26 December 2004 Indian Ocean tsunami stressed the need for assessing tsunami hazard in vulnerable coastal areas. Numerical modeling is but one important tool for understanding past tsunami events and simulating future ones. Here we present a robust simulation of the event, which explains the large runups and destruction observed in coastal Thailand and identifies areas vuln...

[1] The three-dimensional (3-D) shoaling of large-amplitude internal waves (LAIW) is studied in the framework of a fully nonlinear nonhydrostatic numerical model. The vertical fluid stratification, parameters of the propagating waves and bottom topography were taken close to those observed in the northern part of the Andaman Sea. It was found that three-dimensional evolution of LAIWs propagatin...

The three-dimensional nature of breaking Rossby waves in the polar wintertime stratosphere is studied using an idealized global primitive equation model. The model is initialized with a well-formed polar vortex, characterized by a latitudinal band of steep potential vorticity (PV) gradients. Planetary-scale Rossby waves are generated by varying the topography of the bottom boundary, correspondi...

Tuned Liquid Dampers (TLD) are among passive control devices that have been used to suppress the vibration of structures in recent years. These structures must be adequately presentable as an equivalent single degree of freedom system with long fundamental period. The TLD, located at the top floors of the structure, can dissipate the external input energy into the system through the sloshing ef...

Previous studies on wave-induced pore pressure in a porous seabed mainly focused non-breaking regular waves, e.g., Airy linear waves or Stokes non-linear waves. In this study, breaking-wave induced response sandy was physically simulated with large wave flume. The generated by superimposing series of longer onto the foregoing shorter at specified location. Water surface elevations and correspon...

Fast-moving squall lines observed in the tropical oceans are treated as a gravity wave generated by the latent heat release associated with deep cumulus convection. A simple two-dimensional diagnostic linear gravity wave model forced by a zonally propagating heat source is presented. The effect of cumulus friction, or momentum exchange due to cumulus convection, is included in the wave momentum...
