Quizplus · Accepted Answer

When tributaries join the main river, the channel size increases due to the additional volume of water, which in turn increases water velocity. The amount of discharge, or the volume of water flowing through the river, also increases. With the increase in water velocity and discharge, the total sediment load carried by the river also increases. Therefore, all of these options are correct.
