the probability of a flood event occurring and its potential impact

physical shape or features of the land's surface

the increase in the proportion of people living in cities and towns, often impacting natural land

long-term shifts in temperatures and weather patterns, often linked to human activity

Factors affecting flood risk

Geography

This unit, comprising of three variants, teaches pupils about processes and landforms associated with coastal, river and glacial landscapes. Pupils will learn about the formative processes involved in creating distinctive landforms and of the need for management.

Coastal, river and glacial landscapes

How does urbanisation increase flood risk?

Fewer trees mean less water is absorbed by the soil.

Trees absorb more water, reducing the risk of flooding.

Trees block water flow, causing flooding.

How does deforestation contribute to flood risk?

Which human activity can help reduce flood risk?

Clay soils absorb water more slowly, increasing flood risk.

What role does geology and soil type play in flood risk?

Which river process involves the wearing down of the river's bed and banks?

Which landform is created by deposition in a river's lower course?

The amount of rainfall over a period of time

The river's discharge in response to a storm

What happens to a river’s velocity as it moves from the upper course to the lower course?

Which of these river landforms is typically found in the upper course?

What is the term for the process where materials carried by the river are dropped when the river slows down?
