- annotated diagram
Look up any terms you do not know from the other slides

Below are the notes I took, in the table format you had to use. Those in brown are notes made from the presentation above.



RIVER PROFILE

UPPER COURSE
MIDDLE COURSE
LOWER COURSE
CHARACTERISTICS
Depth
Speed/flow
Width
Slope
steepest slope
(R.Gallagher, R.Parish y J.Williamson)
less steep slope
(R.Gallagher, R.Parish y J.Williamson)




  • The gradient is less steep than in the upper course.
  • The valley gets wider and flatter.
  • (unknown)
land flattens out – no slope
channel is wider & deeper so greater flow
wider floodplain
(R.Gallagher, R.Parish y J.Williamson)
PROCESSES (Work done by river)
erosion – main process ( river has most energy)
DOWNWARDS erosion
soil & stones washed away from the sides
(R.Gallagher, R.Parish y J.Williamson)
both EROSION & DEPOSITION
SIDEWAYS erosion (of river banks) – channel gets wider
  • Erosion is more lateral (or sideways) than vertical.
  • The river has surplus energy which it uses to transport material and erode.
(unknown)
DEPOSITION becomes most important process as river loses energy
(R.Gallagher, R.Parish y J.Williamson)
EFFECTS / FEATURES CREATED
V-shaped valleys
waterfalls
gorges
(R.Gallagher, R.Parish y J.Williamson)
floodplains form
meanders
oxbow lakes
(R.Gallagher, R.Parish y J.Williamson)
  • Meanders are formed.
  • (unknown)
oxbow lakes
(R.Gallagher, R.Parish y J.Williamson)
