  1. Based on the cross - sectional velocity distribution of flow in natural river, computation expression for correction coefficient of kinetic energy is derived

    然後根據天然河流橫斷面速分佈公式,推導了能量方程中動能修正系數的計算公式。
  2. Actually correction coefficient of kinetic energy reflects the non - uniform characteristics of cross - sectional velocity in natural rivers. it is related with hydraulic parameters and can be expressed by chezy ' s coefficient. the larger the resistance of boundary, the more non - uniform the distribution of cross - sectional velocity

    動能修正系數實際上反映了速分佈的不均勻性,與的水力要素有關,可用謝才系數c來表示,水所受的阻力越大,邊界對其影響也就越大,速分佈愈不均勻,導致動能修正系數增大。
  3. The project mainly solved the problems from the flood control, the morphological diversity of river profile and cross section, and the diversity of habitats in the river through the layout of shoreline and structures, the design of river profile and cross section, the design of riverbank protection, which is one effective engineering practice of eco - hydraulic engineering

    治理工程在岸線布置、沿建(構)築物布置、設計、岸坡防護設計等方解決了防洪安全、縱向形態多樣性、形態多樣性以及內棲息地多樣性等問題,是生態水工學理念的一次有效工程實踐。
