RESONANT FORCING OF HARBORS BY INFRAGRAVITY WAVES

[摘要] An extensive study of Barbers Point Harbor, including field wave gaging and numerical and physical modeling, was conducted to analyze the harbors response to infragravity wave energy. Infragravity waves have been defined as waves whose periods are greater than 25 sec. Field data collected over a 4-year period were used to calibrate the numerical model while eight extreme events were simulated in the physical model. Agreement between the numerical model, physical model, and the prototype data is good. The importance of spectral shape in the frequency domain also was analyzed by comparing the results from broad and narrow spectra.
