WebOver geological time, a stream will erode its drainage basin into a smooth profile similar to that shown in Figure 13.2.6. If we compare this with an ungraded stream like Cawston Creek (Figure 13.2.2), we can see that graded streams are steepest in their headwaters and their gradient gradually decreases toward their mouths. WebFlooding is a natural phenomenon that occurs when water overflows its banks and spreads onto the surrounding land. Rivers are one of the most susceptible areas to flooding due to their location, topography, and geology. Flooding can cause severe damage to both human life and property, as well as ecological systems.
