Distribution of erosion rates in a subglacial channel before and after a confluence with another channel.
The dashed line is the erosion rate with the initial discharge and sediment load of the main channel, the black arrow is the location where the secondary channel discharges water and sediments, dotted line is the erosion rate with the final sediment discharge and sediment load (sum of the contributi...

description |
The dashed line is the erosion rate with the initial discharge and sediment load of the main channel, the black arrow is the location where the secondary channel discharges water and sediments, dotted line is the erosion rate with the final sediment discharge and sediment load (sum of the contribution of the two channels), the red line is the distribution of erosion rate before and after the confluence. In A) and B) the secondary channel is adding only water in the main channel while in C) and D) it is also adding sediment load. In A) and C) the erosion rate is higher after the confluence while in B) and D) it is lower. |
