Is annual precipitation high or low here?
high
What direction does the river Dee start flowing in?
south easterly, eroding this heavily glaciated upland landscape formed of igneous and metamorphic rocks
What what happens near Chester?
the river meanders across a wide floodplain, eroding softer rocks and depositing sediment
why does the river Dee become straight?
a section is artificially straightened giving it a man-made landscape
how is the Wirral estuarine lands cape formed?
by further deposition occurring
What human activity is causing change in the river Dee?
channelisation increases discharge and velocity
a series of reservoirs were built
earth embankment protected agricultural land and properties preventing further development of the floodplain landscape
What physical factors cause change in the river Dee?
a 1m sea level rise will replace marshy landscapes
a rise in sea level will destroy rhe estuary landscape
