Modified watershed processing with SAR velocities for individual glacier drainage basins on ice sheets

Individual drainage basins of ice sheets specify the glaciated area that is drained by a single outlet glacier. These catchments are needed to partition mass balance measurements to the single glacier level. Until recently, complete glacier inventories that contain annotated basin information were m...
