數值計算方法已成為研究波浪在近岸的傳播變形及其與障礙物之間的相互作用的主要方法之一。Huge waves are whipped up by high winds associated with tropical cyclones or strong monsoon winds while heavy swells can be produced by tropical cyclones a thousand kilometres away. people who are at the sea or near the shore might get hurt or even lose their lives if they are not careful
熱帶氣旋或強烈季候風可以吹起很大的風浪,遠至千里之外的熱帶氣旋亦能傳來巨大的涌浪,處于海上或近岸的人士,一不小心就可能受到傷害,甚至喪失性命。The magnitude of set - up is a noticed number. 2 ) the wave has improved the magnitude of bottom stress in the shallow water, and decreased the current velocity
2 、在近岸淺水地區,考慮波浪作用后的底摩擦應力明顯增加,引起流速的減少及水位的減小。In the end, in view of the fact that boussinesq - type equations and the mild slope equations are deduced from different hypothesis conditions and behave differently in simulation of wave propagation, the numerical results of wave propagation effected by strong non - linearity are given by the nonlinear three - dimensional mathematical model which was established for the calculation of 3 - d wave particle velocity and wave pressure and suitable to small size waters of arbitrarily varying depth
最後,鑒于boussinesq型方程和緩坡方程是在不同的假設條件下推導而來,應用於描述近岸水域波浪的傳播變形時具有不同的特點。本報告根據作者所建立的可以對任意水深點流場與波動凈壓力場進行求解、適宜水深任意變化水域非線性波傳播的數學模型,提供了在較強非線性作用下波浪傳播的數值模擬結果。Experiences show that it is an effective and feasible way to similate the wave transformation in mathematical ways in real coastal engineering
實踐表明,在諸多方法中應用數學模型來模擬波浪在近岸地區的傳播變形是經濟的、可行的。The effects of waves transformation, refraction, diffration, reflection and breaking are all due to the depth of water, varying topography, bottom friction, obstacles and current as waves proceed from offshore to near shore regions. some basic parameters which are relevant to the cost of buildings as well as the type of structures are determined by the wave factors since these projects are placed in near shore area, so it is of great importance to study the regularity of wave transforming
外海波浪傳入近岸淺水區受水深、地形、底摩擦、障礙物以及水流等因素的影響,會發生變形、折射、繞射、反射和破碎等各種現象,然而大部分海洋及海岸工程位於近岸地區,該地區的波浪要素將是確定工程造價、建築物型式等最基本的參數,因此研究近岸地區波浪的變化規律具有重要意義。Wave off into shallow waters, seabed by the friction effect change steep wave front, trough ice, water points trajectory showed reciprocating flow, but also to the shore into the flow speed usually return rate greater than offshore, the net result of sediment at the bottom to the shore handling, and was the shock waves on the shore with the water current - riviera online accumulation
外海波浪傳入近岸淺水區,受到海底的摩擦作用,波鋒變陡、波谷變緩,水質點運動軌跡呈現往復流動,而且向岸進流速度通常大於離岸迴流速度,導致底部泥沙凈向岸搬運,並被激岸浪的上沖水流帶至海濱線上堆積。分享友人
