查询词典 shoaling water

Tidal hydrodynamics play an important role in the change of sediment concentration, especially in the estuarial regions, with the shoaling of water depth, the phenomena becomes very obvious.

Now here, dearest Sophie, I enter into shoaling water, without a chart; and I am afraid I may run myself aground; being, as you know, no great hand with a pen.

First the relationship of shoaling coefficient and relative water depth in regular and irregular wave fields has been analyzed. The experimental result shows that shoaling wave height decreases at first then increases until wave breaking. The broken wave height of regular waves is smaller than irregular waves with same wave steepness and relative water depth.

本文首先就规则波及不规则波实验分析波浪的浅化系数与相对水深之关系，实验结果显示浅化波高有先减后增之趋势，在碎波前达到最大，碎波后之波高在相同水深与深海波浪尖锐度成反比，规则波碎波后波高较不规则波小。

The Fourier approximation method is applied to solving wave height and wavelength problems of waves shoaling、for providing a normalization concept. We normalize the waves scope of depth and deep water to breaking depth into the range of 2~1. Finally、we check the experience formula computations.

After introducing the Boussinesq terms, which makes Boussinesq equation applied in the middle water depth and mild slope, and the wave energy loss term, the numerical modal of Boussinesq equation can accurately simulate irregular wave shoaling、refraction—diffraction and reflect in deep and shallower water.

在Boussinesq方程波浪数学模型的建立过程中，采用适用于中等水深（h／〓≤0.5）和缓变地形的Boussinesq项的修正形式，同时在基本方程中增加了波能损耗项，使该模型能够较精确地模拟波浪的浅水变形、折射、绕射、反射及其综合影响。

In shoaling process, the main peak frequency of broken wave spectra moves to lower frequency. With decreasing relative water depth, both the ratios of wave spectral energy at twice and triple peak frequency to main peak frequency increase. and when the value of the nonlinear parameter increases, both the ratios increase, too. The Stokes third order wave theory has the same tend but overestimates the value quantitatively.

波浪浅化时，碎波后主频频率有往低频移动之现象，且波浪进入浅水区，相对水深减小，非线性参数Ursell number越大时，二倍主频及三倍主频与一倍主频能量比值均有增加之现象，与 Stokes三阶理论有相同之趋势，但实验之比值在定量上小於Stokes三阶理论值。

The results are verified from deep to extremely shallow water conditions. The shoaling waves, standing waves, 3D disturbance waves, tidal waves and solitude waves are simulated and verified,and waves over an underwater bar,the diffraction near single breakwater, breakwater gap, offshore breakwater, Breakhoff experiment are taken into account in this model. Furthermore, the wave harbor resonance under special topography, and "Bragg" resonance are simulated. The wave refraction problem under current fields,the nonlinear wave refraction-diffraction under "Arthur" current field, and the wave propagation under slowly varying current field are studied. The favorable calibrations show the model's feasibility in dealing with the wave nonlinearity and simulation in both deep and shallow water.
