River Tees

River Tees

1. Location

   • The source of this river is Cross Fell and the ending of the river is in the North sea. Its Located in the North East of the UK and the river flows through many places such as: Darlington and Barnard Castle.

2. Upper Course

   • The upper course is found in the high lands and flows through V-Shaped Valley's. It is very powerful in its flow due to the erosion. It flows 600m above Sea level cutting through waterfalls such as: Cauldron Snout
     • Cauldron Snout (Water Fall): This is near Cow Green reservoir. This waterfall is 200 Yards long. This is the longest waterfall in the UK
     • Cross Fell (Source): Up in the empty Mulan Hills was a highland 600 m above sea level was an average of 1200 ml of rain per year.

3. Middle Course

   • Flood plains on each side are 10cm and tend to be quite wide. Waterfalls are most likely found here such as: High Force
     • High Force ( Waterfall ): The river flows over a band of hard and soft rock. Then the river erodes the soft rock faster than the hard rock. Therefore the soft rock is eroded to form a plunge pool and then moves to form an unsupported hard rock step . The unsupported hard rock then falls apart and the waterfall all ,moves backwards creating a gorge. The names of the hard rock (Whinsill) and soft rock (Limestone and Sandstone). The sft rock is very soft and breaks quite easily and dissolves much easier than the hard rock. This is now known as a tourist attraction.

4. Lower Course

   • The Lower Course is very flat, tidal and flows into the north sea
     • Yarm ( Meander ): This town is on the meander bend. This has a big water supply and has made a great defensive site however this took a very long time
       • Seal Sands (Tidal Estuary): This is flat land which is quite tidal and deposits drained mud. Then it became flat land, large and quite deep also the water became polluted.
     • Stockton (Human interaction): This is made up of cut off meanders that have been used to control flooding and tees barrage
