River Ice Analyses and Roughness Calculations Using Underwater Drones and Photogrammetric Approach
Hydrological Processes, Volume 40, Issue 7, July 2026.This study presents a methodology for determining hydraulic roughness (Manning's n) of fluvial ice using underwater drone and Structure from Motion (SfM) photogrammetry. The findings show that cost‐efficient equipment can be used to determine Manning's n for river ice, which supports modelling efforts, especially under intense warming in northern areas.
