Spatiotemporal Variability of Velocity and Influence of Glacier Thickness Using Landsat Imagery: Hunza River Basin, Karakoram Range

The Karakoram Anomaly has been intensively investigated, but the factors that control this anomaly, such as glacier velocity, topography, and mass balance, remain poorly understood. To improve our understanding of balance Glacier, in study, spatiotemporal variability four velocities Hunza Basin range were surveyed using co-registration optically sensed images correlation (COSI-Corr) on Landsat imagery from 1993-2019. results show velocity Gulmit Glacier increases with a rising altitude terminal. three other glaciers initially display high followed by decrease terminal, maximum attained middle glacier. In addition, produced slight gain, all mountain exhibiting clear regional acceleration ice deformation Batura diminished at an average rate 8.49 %. However, topography base physical require further analysis to determine their contribution observed changes velocity. present work, multi-temporal remote sensing image interpretations carried out kinematics, which could enhance change mechanisms.
