几种新型仪器在水文测验中的应用分析

Application of Several New Surveying Instruments in Hydrometric Measurement

水文测验是水文工作的一个重要组成部分,可为河床演变和各种水利工程的设计提供第一手的资料。新型量测仪器的应用大大提高了水文测验的效率,相对于传统的测验方法,正日益显示出其优势。本文就水文测验中流速、水位、波浪、含沙量、泥沙级配、推移质输沙率等代表性新型仪器做一初步的介绍,并讨论了其中存在的问题和以后有可能发展的方向。

Hydrometric measurement is an important part of the hydrologic work, which could present the primary data to fluvial process analysis and hydraulic engineering design. The application of the new surveying instruments in hydrometric measurement is largely improving efficiency and takes more superiority compared with the traditional methods. In this paper, the new representative instruments of velocity, water level, suspend sediment concentration, grain size and bedload transport rate in river hydrometric measurements were briefly introduced. Also, some problems and prospects for the future research were discussed.
