I'm sorry, but I am unable to draw sketches. However, I can describe the shape of the long profile of a river for you. The long profile of a river typically shows a gently sloping gradient from the source (where the river originates) to the mouth (where the river meets a larger body of water, such as a lake or ocean). The profile may include various features such as rapids, waterfalls, and meanders. The source of the river is typically located at a higher elevation, while the mouth is at a lower elevation.
