  4. HYDROSPHERE Stages of River DevelopmentUpper Middle Lower

  5. HYDROSPHERE The upper course can be considered the youngest course. • Water flows quickly through a narrow channel with a steep gradient. Although the water flows fast through narrow sections, the overall speed is low. • It cuts downwards. This vertical erosion results in a number of distinctive landforms including the steep sloping v-shaped valley.

  6. HYDROSPHERE The middle course has taken longer to develop and is older than the upper course. • Water flows through a wider channel with a less steep gradient but less friction means overall speed is higher. • It cuts downwards and sideways. This lateral erosion results in a number of distinctive landforms including meanders, river cliffs and sections of flood plain.

  7. HYDROSPHERE The lower course has taken a very long time to develop. • Water flows down a wide valley with a very shallow gradient. Moving steadily as a body of water there is very little friction so overall speed is high. • The river cuts sideways, trough lateral erosion; enlarging meanders and creating ox-bow lakes, depositing sediment as levees.

  8. HYDROSPHERE • Upper course • V-shaped Valley • Waterfalls and Gorges • Rapids • Middle course • Meanders • Flood plain • Lower course • Ox-bow lakes • Levees • Deltas Need to be able to describe and explain (with diagrams)...
