Abstract
Aiming at submerged flow of specific type of weir , because of its uncertainty of flow coefficient , side contraction coeffi-cient and submerged coefficient , it is difficult to use empirical coefficient to infer and calculate flow of overflow weir .The article puts forward accurate method of deduction and calculation of submerged flow in specific type of weir : based on physical model ex-periment data , relative level of weir upstream and downstream has been correlatively analyzed , correlative equation has been gotten;and then secondary analysis on parameters and flow in the equation , finally the equation of flow -weir head-weir downstream has been calculated .By experimental verification , the equation of deduction from the method is highly precise .The method can be ap-plied to similar multifactorial correlation analysis .关键词
