The invention discloses a hydrological survey device and method based on an unmanned aerial vehicle technology. The hydrological survey device comprises an unmanned aerial vehicle, a Doppler ultrasonic flowmeter, a camera, a wireless communication module, a data processing module, a PH sensor, a water depth sensor and a release mechanism. The Doppler ultrasonic flowmeter, the camera, the wirelesscommunication module, the data processing module and the release mechanism are connected with a rack of the unmanned aerial vehicle, the data processing module is connected with a PH sensor, a water depth sensor and a connecting piece of the release mechanism are connected and suspended on the lower portion of the unmanned aerial vehicle, and the unmanned aerial vehicle is controlled by an unmanned aerial vehicle control system to reach the position above a river channel. Data measured by the PH sensor and the water depth sensor are released through the release mechanism and received and sentthrough the wireless communication module, the data processing module processes the data, and the unmanned aerial vehicle is perpendicular to water flow and consistent with the water flow in speed during measurement. The device and the method overcome the problem of inaccurate measurement caused by incapability of being perpendicular to water flow and consistent with the flow velocity of the waterflow during original manual survey of river hydrology, and have the characteristics of simple structure, accurate measurement, facilitation of rapid and accurate discovery of a pollution source, andsimplicity and convenience in operation.
