摘要
介绍利用水工建筑物、流速仪、堰、槽进行量水的基本原理及各自适用条件 .从量水仪器、设施的性能、价格及灌区经济发展水平等方面 ,分析目前在灌区量水仪器、设施的开发研制方面存在的主要问题 ,以及灌区量水难以普及的主要原因 .提出应结合灌区渠道防渗工程建设 ,合理选择和建设量水设施 ,并根据灌区经济发展水平 ,分步骤研制和推广便携式或固定式量水仪器 ,最终实现灌区量水自动化的灌区量水实施方案 .
Hydraulic structures,velometers,weirs,and flumes are used to gauge water in many irrigation districts.The fundamental principles and suitable conditions of these water metering methods are introduced in this paper.The main problems in the development of water metering instruments and facilities as well as main causes of difficulty in popularization of the methods in irrigation districts are analysed.It is suggested that selection and construction of water metering facilities should be combined with canal lining in irrigation districts.It is also pointed out that for realization of automation of water metering it is necessary to develop and popularize portable and stationary water metering instruments step by step based on economic development levels in irrigation districts.
