THE PROPAGATION OF WATER WAVES IN PRISMATIC CHANNELS

[摘要] Short waves in a channel can present navigational problems and may excite harbor oscillations. Channel sidewalk may reduce much of this wave energy, if they are sufficiently porous or they are sloped. Previously we presented a model for wave propagation in prismatic channels of arbitrary cross-section utilizing a numerical eigenfunction expansion. Here a series of small scale laboratory experiments were conducted to verify the numerical model. Comparisons of the numerical model to the experimental data are made for water surface profile and for eigenfunctions. The possibility of resonance between the edge wave and the second harmonic of the incident wave is also studied.
