The Faith "Great Debate" sedimentation and erosion topic

Water follows the lowest path avaliable, so wouldn't the waters concentrate into the first cutting? It seems to me that what you'd wind up with is a flat table with a big channel carved out, following the meanders of the rivulet that began it.

Well, I think that's a debatable proposition, and certainly one we should be able to confirm from the local geology, but it would depend on the area in question. Just to be sure are we still talking about the Grand Canyon? Because the only source of water I'm aware of in that area is the Colorado River, which exhibits exactly the qualities I described. They would quickly input into the first rivulet, which would become the main channel of outgoing water, which is exactly the sort of drainage pattern we see in watersheds to this day. That's a great idea; that's an experiment that I performed in 8th grade Earth Science so its quite easy to do. I suggest you do it in a box so you can correct for the lay of the land, and experiment with various configurations of land and lay. It should be quite illuminating. If you had a digital camera you could both easily record the experiment and share it with the rest of us. Absolutely, but I really like the idea of performing it ourselves. Also I would reccommend you view satellite imagery of various watershed areas; its easily found on a google search.
