Integrating SfM, LiDAR and TLS for High‐Resolution Monitoring of Palsa Surface Changes and Degradation Dynamics

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Understanding fine‐scale surface changes is crucial for quantifying ecosystem dynamics and detecting landscape changes. Palsas, comparably small peatland elevations with an ice‐rich permafrost core, undergo natural cycles of growth and degradation. They can also serve as indicators of climate change in subarctic regions. Because they typically

Validation of a Particle Image Velocimetry Algorithm Through Comparative Field and Laboratory Analysis

River Research and Applications, EarlyView.
ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...

IVyTools: Space–Time Image Velocimetry for Streamflow

River Research and Applications, EarlyView.
ABSTRACT Accurate streamflow measurements are essential for hydrologic monitoring, flood forecasting, and water resource management. Traditional in situ methods, although reliable, are often impractical or unsafe during flood conditions or at inaccessible locations. Image velocimetry techniques offer a potential non‐contact alternative, yet operational
