When tributaries join the main river, the channel size increases due to the addition of water and sediment, water velocity increases due to the extra volume of water, and the amount of discharge increases as the tributaries add more water to the main river. Additionally, the total sediment load increases as sediment from the tributaries is transported downstream.
