CHCNAV Apache 4 USV Used For Hydrographic Survey Project

Rivers nourish the land, maintain ecological balance, and promote agricultural development, but if changes in the flow of major rivers are not known, floods or droughts may occur. Velocity and flow monitoring have always been a headache for hydrographic measurement from large rivers to small streams. Early representative equipment such as mechanical current meters, printed current meters, electromagnetic current meters, etc., can only measure single-point flow velocity and cannot accurately measure the cross-section flow. The emergence of the Acoustic Doppler Velocity Profiler (ADCP), which can measure the velocity of each layer of the entire section, more intuitively and accurately displays the flow of rivers, so hydrological users favour it.
