.... The combined model includes the effects of the quay wall and the sea floor in a harbor on wave propagation and also takes account of shoaling, refraction and nonlinear wave-wave interaction. The numerical tests show that the present combined model is capable of calculating the motion of a floating body induced...

... of height in a harbor with asymmetrical breakwaters. INTRODUCTION Water wave diffraction is the phenomenon where waves encounter an obstacle or gap and propagate into a sheltered area at a different angle than the original wave train. This action is of high concern to designers of ports and harbors who...

... ABSTRACT The long breakwater of Tinian Harbor, located at the southwest shore of Tinian of the Northern Mariana Islands in the western Pacific region, is deteriorating. The Harbor has been exposed to consistent wind sea, distant swell, and frequent tropical storm waves. Typical wind wave...

... ABSTRACT Long gravity waves entering into port and harbors create much higher wave agitation. It is required to dissipate this wave energy for safe loading and unloading operation. Sloped rubble mound breakwater is used normally. But it occupies significant space of the harbor. In order...

... at the bottom and the east side. The WSW wind wave is about 65%~81% and 49~75% of the total height. INTRODUCTION Wave is one of the main driving forces of sediment motion and beach evolution, and also is the main factor affecting the normal docking and operation of harbors and wharves. In the planning...

... ABSTRACT A field monitoring and numerical modeling study was conducted to evaluate impacts of infrastructure modifications for improving navigation at Kikiaola Harbor in Kauai, Hawaii. The harbor, sitting on a coral rocky bottom with the southward entrance exposing to Pacific Ocean...

... Abstract The sudden sedimentation is a rapid deposition of suspended sediment in a short time, which causes the depth of a channel shallow. It is important for manager, engineer and designer to understand the phenomenon in a harbor. A 3D numerical model of sediment transport based...

... Abstract With the rapid development of harbor construction in China and in other developing countries, environmental protection and ecological harmony have become decisive factors in harbor planning, design and construction management. Green harbor concept and ecological strategies...

... that the wave overtopping rate is smaller than 0.02 m 3 /s/m though the wave transmission coefficient is 0.35 when the wave overtopping rate is 1.6 m3/s/m for usual design height of breakwater which is 0.6 times of incident wave height. Moreover the wave transmission inside a harbor during a storm condition...

... Abstract Infragravity waves observed inside a harbor may consist of free waves not only propagated from offshore but also generated (released) at harbor entrance due to reduction of wave groups by diffraction and breaking. In this study, numerical simulations of both wind and infragravity wave...

... Abstract This paper describes the numerical modeling of waves, currents, and sediment transport at Pillar Point Harbor, CA. The Coastal Modeling System (CMS), developed at the US Army Engineer Research and Development Center (ERDC) with fully integrated wave, current, and sedimentation models...

... Abstract By Physical experiment, the harbors wave height distribution and the wave overtopping of different wharf structural form were studied. With the example of one wharf extension project, the wave heights in harbors and the wave overtopping in different wharf surface elevation were...

... Abstract The storm surge is a coastal flood phenomenon of rising water, which is an important safe factor for harbor and coastal engineering. A mathematical model was established to help estimate the rising water during the No. 9711 typhoon in Weifang harbor, which is protected by the double...
