Bedrock is present at three sides (brown; side closest to viewer not shown) and the glacier’s bottom provides an ice roof to the channel (white). Parameters shown are water depth, d, and channel width, w. The channel is completely filled with water (blue) that transports saltating (curved arrows) and suspended sediment (straight arrows).
