Waterfalls commonly form where water rushes down steep hillsides in upland areas and quickly erodes the rocks. The height and number of waterfalls

The Bradshaw model allows us to see do the river’s characteristics such as‚ average velocity‚ channel depth‚ load quantity and particle size of the load‚ increases or decreases and how much do they change. However this model can’t be exactly right for all rivers around the world because of the external factors that effects the rivers. Average
