Deadline is closed
The project explores new techniques for monitoring streamflow dynamics using unmanned aerial systems (UAV, UAS). The aim is to develop a robust method for streamflow monitoring by UAV, applicable for flow velocity determination in ungauged streams or for assessment of extreme flows. The research should develop and test new approaches for indirect quantitative assessment of flow velocity and its distribution in montane channels, using UAV imaging. UAV image velocimetry analysis will be based on the identification and tracking of seeded particles in the stream from hi-speed UAV imaging. The image analysis will extract the particle trajectories and velocities from the imagery stack and determine the flow velocity patterns. The results will be validated by continuous monitoring and in-situ velocity measurement and used for accuracy improvements of streamflow modeling of montane streams. The study area is located in the headwater part of the Sumava mountains (Czech Republic), where the research will benefit from the long-term research efforts and the experimental monitoring network. This research project fits the long-term research topics of the research group of Hydrology and of the HyDrone team. The applicant will benefit from the cooperation of the research team in the fields of UAS technologies, hydrology, and modeling.
