Channel patterns are found in rivers, streams, and other bodies of water that transport water from one place to another. Systems of branching river channels dissect most of the sub-aerial landscape, each in a valley proportioned to its size. Whether formed by chance or necessity, by headward erosion or downslope convergence, whether inherited or newly formed.[1] Depending on different geological factors such as weathering, erosion, depositional environment, and sediment type, different types of channel patterns can form.
