Measurement of river discharge during flooding events has especially been a challenging and dangerous task in the southwestern US, where flows can be flashy, laden with sediment, at high velocity. Small unoccupied aircraft systems (sUAS) deployed to access unsafe field sites capture imagery for measuring surface flow velocity discharge. This paper compares estimation eight sites—located or near...

Recent advances in image-based methods for environmental monitoring are opening new frontiers remote streamflow measurements natural environments. Such techniques offer numerous advantages compared to traditional approaches. Despite the wide availability of cost-effective devices and software image processing, these still rarely systematically implemented practical applications, probably due la...

Space-time image velocimetry (STIV) technology has achieved good performance in river surface-flow velocity measurement, but the application a field environment is affected by bad weather or lighting conditions, which causes large measurement errors. To improve accuracy and robustness of STIV, we combined STIV with deep learning. Additionally, considering light weight neural network model, adop...
