解放以来,我国水文测验工作有很大发展,测验设备技术水平有很大提高,但在高流速高含沙量条件下的测速、测深和测沙技术未能得到很好解决,影响着水文资料成果质量的进一步提高,不能适应水利水电建设和防洪斗争的需要。为此,水电部决定将高流速高含沙量水文测验技术列为1983～1985年科研重点攻关项目。为了落实这一重点攻关项目的研究工作,水电部水文局于今年5月10日至15日在南京召开了高流速高含沙量水文测验设备科技攻关协调会。参加会议的有科研单位、工厂、有关流域机构和省(区)水文部门的科技人员共30人。会议在总结经验的基础上,讨论了高流速高含沙量水文测验没备主要技术指标;
Since the liberation, great progress has been made in hydrological testing in our country, and the technical level of testing equipment has been greatly improved. However, the technologies of velocity measurement, sounding and sand measurement under high and high sediment concentration conditions have not been well solved and have an impact on the hydrology The further improvement of the quality of data and achievements can not meet the needs of water conservancy and hydropower construction and flood control struggle. To this end, the Ministry of Electricity and Water decided to high-speed high sediment concentration hydrological test technology as 1983-1985 key research projects. In order to carry out the research work on this key research project, the Hydropower Bureau of the Ministry of Electricity and Water has held a coordination meeting on scientific and technological research on high-flow and high-sedimentation hydrological testing equipment in Nanjing from May 10 to May 15 this year. A total of 30 scientific and technical personnel from scientific research institutes, factories, watershed institutions and the provincial (district) hydrological department attended the conference. On the basis of summing up the experience, the meeting discussed the main technical indicators of high flow rate and high sediment hydrological test,
