When aggradation (the process of adding sediment to a channel) greatly exceeds erosion, braided channels are likely to develop. This is because there is an excess of sediment that can't be transported downstream, leading to multiple channels forming and braiding together. V-shaped valleys, meandering channels, and deeply incised canyons are more likely to form when erosion outpaces aggradation, while straight, steep-walled channels may form in areas with steep gradients or resistant bedrock.
