目前，灌区测水的主要形式可分为两大类，一是利用流速仪测水，二是利用建筑物测水。流速仪测水精度较高，但费工费时，很难为运行管理提供即时数据，不利于水量调配；测水建筑物虽能克服以上缺点，但测水精度较低，且种类繁多，工程投入和维护费用较高。因此，灌区在选用... At present, the main forms of water measurement in irrigation areas can be divided into two categories, one is the use of current meter to measure water, and the other is to use buildings to measure water. However, it is difficult to provide real-time data for operation and management, which is not conducive to water allocation. Although water testing buildings can overcome the above shortcomings, the accuracy of measuring water is low and the variety of engineering inputs and High maintenance costs. Therefore, the irrigation district is choosing ...
