治淮委员会勘测设计院自1955年初开始进行流域规划的水文计算,至1956年初结束。规划中水文计算的任务是利用全部水文气象资料综合整理、分析研究,按照流域规划各专业组(水利计算、航运、发电、农业……等)的要求,提出所需的各项水文特征值的数据,并将各项水文材料有系统地编制能阐明各项水文特性的文件与图表。全部工作内容有:流域自然地理特性资料的收集与整理,气候特性的研究,年径流特性的研究,洪水特性的研究,以及泥沙、水位等特性的研究。今将其中几个主要水文计算问题的研究情况介绍如下。
The Huaihua Commission Survey and Design Institute started hydrological calculations of river basin planning from the beginning of 1955 and ended in early 1956. The task of hydrology calculation in the planning is to make use of all the hydrological and meteorological data to collate, analyze and study, and put forward the required hydrological eigenvalues according to the requirements of each specialized group (water conservancy calculation, shipping, power generation, agriculture ...) Data and systematically compile hydrological materials to produce documents and charts that illustrate the hydrological characteristics. All the work includes: the collection and collation of natural geographical features of watershed, the study of climatic characteristics, the study of annual runoff characteristics, the study of flood characteristics and the research on the characteristics of sediment and water level. Nowadays, the research on several major hydrological calculation problems will be introduced as follows.
