Tees Basin Local Case Study Flashcards
describe the location of the tees basin
in the north east of england, flowing from cross fell to the north sea
name some urbanised areas the river tees flows through
bernard castle , darlington, middlesbrough , yarm
what are some physical characteristics of the river tees in the upper course
-steep sided V shape valleys
-more vegetation, but a lot of deforestation in the last 1000 yrs
-peat soil, stores a lot of water and carbon
-first place frontal rainfall will pass
what are some physical characteristics of the lower course of the river tees
-low lying flood plain
-drier climate, less rainfall especially relief rainfall
-more alluvium soils which are very fertile and have high rates of infiltration
-more arable farming and crops here
what are some human characteristics of the upper course of the tees basin
-limited settlements, some small villages and farms
-some leisure/recreation at high forge which attracts natural tourism
-lots of hill sheep farming, grazing so little need for irrigation
-large amounts of dams and reservoirs e.g cow green
what are some human characteristics of the lower course of the tees basin
-major urban developments such as darlington (100K pop), teeside (300K pop)
-more pasture farming, dairy and beef, higher demand for irrigation
-previous industry will have used alot of water and river streams for dumping
is rainfall higher in Middleton in Teesdale or Darlington
middleton, it’s in the upper course
is temperature higher in darlington or middle in teesdale
darlington, more urbanised, urban heat island, albedo
does darlington ever see soil moisture deficit on average
no
will darlington start to see more soil moisture deficit and why
yes, because of a lack of rainfall in the summer due to climate change
why woukd middleton on teesdale have a longer period of surplus than darlington
because it’s higher up course closer to the pennines, which means it will experience more relief (orographic) rainfall
when did the tees basin experience and major flood
25th september 2012
what were some physical characteristics of this flood
-most intense storm here in 30 years
-frontal rainfall, in area of low pressure
- 973mb pressure, lowest since 1981
-2x normal amount of rain in september
what we’re some human causes/influences of this flood
-urbanisation, many impermeable surfaces in darlo and teeside caused little infiltration and mkre surface run off
-agricultural and farming intensified, use of machinery and soil compression
-the removal of hedgerows on a small scale reduced interception etc.
what we’re some impacts of this flood event
-major road closures on the A66 for example
- ppl evacuated into temporary housing
-east coast mainline train closed
-more than 100 vehicles trapped on a 30 mile stretch on the A1
