When it rains in highlands, water that flows downhill gets drained into the space created by the root system of plants. Due to this, chance of flooding is greatly reduced. When plants are absent, especially in rocky areas, rocks prevent water from seeping into the ground. This phenomenon is also observed in paved roads. Since there is no room for water to seep, flooding occurs in nearby water bodies. When a layer of water runs off a rocky surface, it reduces friction and the following layers water will run more freely as there is less friction. If more water is dumped into rivers and lakes than they can handle, the floods
