Examples
- Calculation of natural runoff of the yellow river is the basic work for water resource planning , distribution , production and scientific research of the river
黄河流域天然径流量的计算是黄河流域水资源规划、调度、生产、科研的基础性工作。 - Abstract : calculation of natural runoff of the yellow river is the basic work for water resource planning , distribution , production and scientific research of the river
文摘:黄河流域天然径流量的计算是黄河流域水资源规划、调度、生产、科研的基础性工作。 - The results show that flood variety should be the main aspect in the study of measured runoff variety of the yellow river upstream , drought ( or water interception ) study should be stressed in the study of natural runoff variety of measured and natural runoff variety the yellow river downstream
结果认为，对黄河上游实测径流变化的研究应以洪水的变化为主，对天然径流变化的分析应以干旱（断流）为重点；而对黄河下游实测径流变化及天然径流的研究均应以干旱（断流）为主。 - According to the concept of available water supply , the calculation methods about available water supply of the large scale reservoir are studied and the concrete procedures of the long - series regulation method are proposed . through the calculation of the monthly natural runoff every year , water incomes under present engineering status , and the long - series dynamic water usage regulation of the 32 large scale reservoirs in shandong province , available water supply under assurance rates of 50 % , 75 % and 95 % are obtained . according to the analysis of runoff characteristics of each reservoir ( multi - year mean runoff depth and runoff coefficient ) , the relationship between water supply incomes under different assurance rates for current year and the year of 2010 , the reservoirs with water supply potence are given
根据对可供水量概念的理解，本文对大型水库可供水量的计算方法进行了探讨，提出了采用长系列调节计算的具体方法；通过对山东省32座大型水库的历年逐月天然径流量、现状工程情况下来水量、长系列变动用水的调节计算等多个步骤，得出了各水库50 、 75 、 95三种保证率的可供水量计算成果，并对每个水库的径流特性(多年平均径流深及径流系数) 、全省大型水库现状年及2010年的不同保证率的可供水量与来水量的关系进行了分析与研究；分析提出了具有供水潜力的水库。
