About

Giulia Marchetti is a fluvial geomorphologist whose work bridges remote sensing, robotics, and river science. Her primary research focuses on developing innovative, low-cost methods for measuring riverbed sediment grain sizes—a critical parameter for understanding river dynamics, habitat quality, and landscape evolution. Her most cited work, a 2017 proof-of-concept study, pioneered the use of robotic photosieving from low-cost multirotor small unmanned aerial systems (sUAS). This approach revolutionized traditional fieldwork by enabling rapid, repeatable, and non-invasive grain size analysis from aerial imagery, dramatically reducing time and labor while expanding spatial coverage. With 59 citations, this paper has become a foundational reference for researchers integrating drone technology into fluvial geomorphology and lotic ecology. Marchetti’s contributions stand out for their practicality and accessibility, making high-resolution sediment characterization available to scientists with limited budgets. Her work exemplifies how engineering and environmental science can converge to solve long-standing field measurement challenges, and she continues to advance automated, image-based techniques that shape modern river monitoring and management.
