Video-Based Measurement of River Surface Velocity: A Review of Methods, Measurement Workflows, and Validation

Unmanned aerial vehicles (UAVs), smartphones and computer vision are expanding the use of non-contact approaches for measuring river surface velocity and estimating discharge. This review combines bibliometric analysis with a qualitative synthesis of video-based river hydrometry, with emphasis on sensing platforms, ima...

Assessing the Temporal Consistency of Intra-Urban Surface Thermal Patterns in Satellite LST Time Series: A Case Study of Zagreb, Croatia

Abstract. Urban surface warming is often investigated using satellite-derived land surface temperature (LST), but short multi-year time series are difficult to interpret because of interannual variability, limited cloud-free observations, and heterogeneous surface characteristics. This study proposes a practical framew...

Severity-Based Mapping of Land-Subsidence Hazard Zones and Critical Hotspots Using SBAS-InSAR and Spatial Statistics: The Konya Metropolitan Area, Turkey

Land subsidence induced by excessive groundwater withdrawal has become one of the most significant geohazards affecting the Konya Closed Basin, Turkey. Although previous studies have successfully monitored ground deformation using geodetic and remote sensing techniques, limited attention has been devoted to transformin...
