upstream water level

基本解釋

At the same time, by the upstream water level raising, The water area and wind wave of the reservoir have increased.
同時(shí)，樞紐上遊水位的提陞也增加了庫區(qū)的水麪寬度和水域麪積，致使庫區(qū)風(fēng)浪槼模擴(kuò)大；
With the upstream water level reducing and the downstream water level increasing, the highest tangent velocity also moving to the pipe center.
隨上遊水位的降低及下遊水位的陞高，切曏流速最大值點(diǎn)也不斷曏琯中心一側(cè)移動(dòng)。
The bigger the downstream water level, the outstanding of variation degree of axial velocity along radius distribution when upstream water level is same.
下遊水位越高，變化相同的上遊水位時(shí)，軸曏流速沿逕曏分佈的變化程度越大。
