  1. In this paper, based on summarizing previous numerical studies on wave transformations, several works are documented : based on the mass conservation equation and euler ' s equation, the extended form of boussinesq equations is derived by using the velocity at an arbitrary water depth as the independent variable, and several terms are added into governing equations to model the effects of bottom friction, wave breaking and subgrid turbulent mixing

    本文在總結概述前人關于boussinesq方程數學模型研究展的基礎上,主要做了以下幾點工作:從質量守恆方程和euler方程出發,以某一水層處水平矢量作為獨立變量,導出包含底摩擦耗能、破碎效應和子網格湍流效應的改型boussinesq方程。
  2. Current. in order to make diffluent piers with low ridge to be popularized and applied, the surface wave of low fr. current is chosen as the research object. we measure the surface wave elements and the velocity distribution of various diffluent piers scheme by the experiment of physical model. we also analyze the average wave height, the the average value of the square of wave, unit width of the wave ' s energy, the probability density distribution of wave height, and the power chart character, so as to reveal the weakening wave mechanism of the diffluent piers

    低fr水流的核心是問題,為了低坎分流墩的廣應用,本研究以低fr水流的表面作為研究對象,通過物理模型試驗,對各種分流墩方案消能工的下游水面要素、流分佈行測試,分析低坎分流墩下游的平均高、均方根、單寬能、高概率密分佈及功率譜特性變化規律,從而揭示了低坎分流墩的削機理。
