In nature, a creek bottom has a variety of stone types + sizes. Depending upon the design requirements, a project may increase or decrease the variation to meet objectives. Slope, anticipated storm flow + other factors may play into the stone mix. Check out these related surfaces: river stones, ghostwood, coarse limestone + trestle basalt.
A proper dry creek will have the ability to handle the majority of storm water that interacts with that associated part of the site for most rain events. The change in contour, along with the characteristic stoney materials of a creek become an effective transitional element or border edge from one landscape condition to another.
