I think that water on walls make an A coming out of the top of a flow point and a V at the bottom farther away from the flow point. What are your thoughts on this?
In my observations in the wild, flow out of drainpipes created an A, and flow over the edge of a wall created a V. That seems intuitively to be something about: the drainpipe has a bunch of water all close together, and then it opens up with more space along the surface of the wall. The water flowing over the edge of the wall is spread out, and then wants to stick together to other water, so it gets pulled closer, forming a V, like how a fountain with a watersheet output at the top gives a V-shaped watersheet. I don’t feel completely satisfied by this though, because I don’t understand exactly why it spreads out when coming out of a drainpipe, rather than continuing to stick together.
