River landforms case study You need to be able to give examples of river landforms. The River Tees Case Study — landforms of erosion and deposition. During a flood the river will deposit its heaviest material first i. In the upper course erosion is the dominant process creating V-shaped valleys , interlocking spurs and waterfalls. Lower course – in the lower course, the land is a lot flatter. Ox-bow lake – downstream of Darlington on R.
BBC Bitesize – upper course features. Hurricane Katrina Case Study. It shows how the river changes over its course. In the upper course of the river, the river cuts rapidly downwards, as the main direction of erosion is verticall. In the middle section the river has more energy and a high volume of water.
The river’s load is large in the upper course, as it hasn’t been broken down by erosion yet. Tree management – dead trees were removed to prevent them being swept away, causing blockages under bridges.
The channel is at its widest and deepest. River profiles Long profile A long profile is a line representing the river from its source where it starts to its mouth where it meets the sea.
Landforms in the lower course of a river. Tees at Barnard Castle.
High Force waterfall on the River Tees. The River Tees Case Study — landforms of erosion and deposition.
Distinctive landforms result from different processes as rivers flow downstream.
They are formed when the river deposits its material faster than the sea can remove it. As the river flows over the hard rock onto soft rock, the biteslze rock will be more easily eroded. Landforms diver from deposition In the lower course the river has a high volume.
Vertical erosion has formed classic V-shaped valleys. C – in the lower course there is a lot less erosion, with only some lateral erosion.

Meanders in the lower course are much larger. Ox-bow lake – downstream of Darlington on R.
This process happens repeatedly which means that the waterfall gradually retreats upstream creating a gorge. Boscastle, Cornwall In Augustthe village of Boscastle saw a month’s worth of rain fall in two hours.

Flood management case study: Tees Waterfall – High Force, R. On the inside of the bend the velocity is much slower and consequently, deposition occurs creating a slip-off slope. BBC Bitesize – upper course features.

Interlocking spurs close to Cauldron Snout on the River Tees. Interlocking spurs are created when the river has to flow around an obstruction for example, hard rock. The River Tees is located in the north of England. The faster water travels around the outside of the bend, eroding the banks through abrasion and hydraulic action.
An area of hard rock, called Whin Sill or Whinstoneis located above a layer of soft rocks sandstone and shale and csse they create the waterfall. Each of these sections have different dominant processes resulting in different features.
The drainage basin of Boscastle is steep and impermeable rock. If you’ve found the resources on this page useful please consider making a secure donation via PayPal to support the development of the site.
It flows east from its source in the Pennines to its mouth, on the North Sea coast. Rivers have an upper, middle and lower course. A – as the river flows bgc there is an increase in vertical erosion. Over time this creates an wtudy which eventually, due to gravity, collapses under its own weight. Boscastle is also located on a confluence of three rivers. Lower course – in the lower course, the land is a lot flatter.
