In order to promote the management of small and medium-sized rivers with high quality, the Ministry of Water Resources and the Ministry of Finance jointly issued the "Notice on the Preparation of the National Overall Program for the Management of Small and Medium-sized Rivers". On July 13, the Ministry of Water Resources held a kick-off meeting to deploy and start the preparation of the overall plan for small and medium-sized rivers. In the future, it will continue to effectively and orderly promote the governance tasks, comprehensively improve the ability of flood control and disaster reduction for small and medium-sized rivers, and contribute to the safety of people's lives and property and the sustainable development of the economy and society. Healthy development provides a solid water security guarantee.
In the treatment of small and medium-sized rivers, the help of ADCP (Acoustic Doppler Velocity Profiler) is indispensable. ADCP is currently one of the most advanced river velocity and flow measurement devices in the world. It helps hydrological departments to obtain online and real-time information on river velocity and flow, so as to grasp the operation status and changing laws of rivers, and provide reliable data for flood prevention and flood control decision-making. It is an important means for digitization to empower the governance of small and medium rivers.
Hi-Target iFlow RP600 ADCP is equipped with HD-MAX depth sounder and K16 GNSS positioning and orientation instrument solution, which can solve the problem of flow measurement in the environment with large sand concentration. According to the joint test conducted by Luokou hydrological station and Hi-Target, the combination of Hi-Target iFlow RP600 ADCP, HD-MAX depth sounder and K16 GNSS positioning and orientation instrument can overcome the influence of harsh conditions with large sediment concentration and complete the ADCP. It provides more means and methods for the flow measurement of the Yellow River under the condition of relatively large sediment concentration. At the same time, this test also demonstrated the excellent performance of iFlow RP600 ADCP in peripheral expansion, installation and debugging, support software, flow measurement results, etc.; in terms of peripheral expansion, iFlow RP600 ADCP can reasonably input other peripherals according to requirements. Parameters are used for ADCP flow calculation, and the peripherals of the equipment have good compatibility; in terms of installation and commissioning, the installation and commissioning process of iFlow RP600 ADCP is convenient and fast, and it is compatible with HD-MAX depth sounder and K16 GNSS positioning and direction indicator The connection is reliable and can be used under the current conditions of large sand concentration; in terms of supporting software, the iFlow flow measurement software can present a wealth of measurement information during the test process and the data analysis process after the measurement is completed, and has a good User experience; in terms of flow measurement results, the self-deviation (standard deviation) of the flow, flow velocity, bottom velocity, cross-sectional area and other parameter data measured by the iFlow RP600 ADCP is within 2.7%, and the measurement accuracy meets the requirements of the ADCP flow test specification .
