Short summary
Sediment transport capacity depends on water velocity and channel width. In rivers, water discharge changes affect flow depth, width, and velocity. Yet, under glaciers, discharge variations alter velocity more than channel shape. Due to these differences, this study shows that sediment transport capacity under glaciers varies widely and peaks before water flow, creating a complex relationship. Understanding these dynamics helps interpret sediment discharge from glaciers in different climates.
