What does it mean to say these processes operate at different scales?

They shape the whole drainage basin and a single landform within it, and they act over centuries as well as during one storm.

Which landforms would you expect to describe in the lower part of your river basin?

Meanders, ox-bow lakes, levees and a broad floodplain, produced where the river is depositing far more than it erodes.

How does the growth of towns in a river basin change the way water reaches the channel?

Tarmac and roofs stop rain soaking in and drains deliver it quickly to the river, so discharge rises sooner and peaks higher after a storm.

Landscapes of the UK

Two UK landscape case studies: a river basin and a coastline

3 things to know
Component 01

Overview

The geology, climate and processes of a river basin and a coastline, their landforms, the effects of towns, farming and groynes, hard and soft engineering, the River Tees from Cross Fell and High Force to Cow Green Reservoir and the Tees Barrage, and the Holderness coast from Flamborough Head to Spurn Head, with the Mappleton scheme.

Questions from this subtopic

Each one with the model answer underneath.

1
What should you be able to say about the geology of the river basin you have studied?
Model answer
Which rocks the basin is cut into and how resistant and permeable they are, and how that controls the shape of the valley, the speed of erosion and where features such as waterfalls appear.
2
How does climate influence the processes at work in a river basin?
Model answer
The amount and intensity of rainfall control discharge and so how much erosion and transport happens, while temperatures around freezing control how much freeze-thaw loosens the valley sides.
3
What does it mean to say these processes operate at different scales?
Model answer
They shape the whole drainage basin and a single landform within it, and they act over centuries as well as during one storm.
4
Which landforms would you expect to describe in the upper part of your river basin?
Model answer
V-shaped valleys, interlocking spurs, waterfalls and gorges, all produced where vertical erosion is strongest.
5
Which landforms would you expect to describe in the lower part of your river basin?
Model answer
Meanders, ox-bow lakes, levees and a broad floodplain, produced where the river is depositing far more than it erodes.
6
How does the growth of towns in a river basin change the way water reaches the channel?
Model answer
Tarmac and roofs stop rain soaking in and drains deliver it quickly to the river, so discharge rises sooner and peaks higher after a storm.
