Research Field

Comparison of wave refraction and diffraction models

Journal of Coastal Research (2000)

Jerome P.‐Y. Maa Tai–Wen Hsu Chih‐Heng Tsai Wen-Jye Juang

Six numerical models: (1)RCPWAVE, (2)Ref/Dif-1, (3)RDE, (4)PBCG, (5)PMH, and (6)MIKE 21's EMS module, were examined for their performance on the simulation of water wave shoaling, refraction, and diffraction. Experimental data for waves traveling across an elliptic shoal were used as a standard for comparison. Although the last four models (i.e., elliptic or hyperbolic model) are capable of simulating strong wave diffraction, reflection, and resonance, those capabilities were not compared because RCPWAVE, Ref/Dif-1, and the physical model experiment are only capable of simulating water wave shoaling, refraction, and weak diffraction. The Ref/Dif-1 had excellent accuracy in the prediction of wave height; the predicted wave direction, however, was not good. The RCPWAVE had accuracy problems in both wave height and direction. The next three models (RDE, PBCG, and PMH) all performed very well on the simulation of wave shoaling, refraction, and diffraction, and they practically provided the same results for the case study presented. The EMS module for Mike 21 was slightly different than the previous three. Regarding the simulation of the passing-through boundary, the PMH model was better because of the nearly exact solution for this boundary. The MIKE 21's EMS module had a faster computing pace, but no output for wave directions and was incapable of including tidal current effects were the major drawbacks.

Peculiar Appearance of Nearly Symmetrical Tidal Flooding Time Along the Western Coast of Taiwan

Journal of Mechanics (2001)

Wen-Jye Juang Ming‐Chung Lin Wen-Jiunn Liou

ABSTRACT During the past several decades, nearly symmetrical tidal appearances, both the time of high water elevation and the tidal range, were noted along the western coast of Taiwan. Research corresponding to anomalous amplifications of tidal range have been well studied by Lin, et al . [1,2], but the particular symmetrical tidal appearance of high water time has not yet been clarified. In this paper, we firstly apply a harmonic analysis to tidal data compiling. Based on the results, the important symmetric appearances of high water time and tidal range can be located. Emphasis is given on the investigation of symmetrical distribution of high water time by superposing two progressive waves that interfere on a topographic shelf with specific width. A conceptual configuration of co-oscillating standing tides is proposed to demonstrate the symmetrical tidal range distributing in the space domain and oscillating in the time domain.
