The diagrams below show how houses can be protected in areas which are prone

to flooding.

范文：

Here's my full band 9 report:

The diagrams compare two different methods of defence for homes which are at

risk of being flooded.

The key difference between the diagrams is that they show flood protection

with and without a stopbank. In either case, the at-risk home is raised on

stilts above ground level.

The first diagram shows how a stopbank acts as a flood barrier to stop river

water from flooding homes. The stopbank is a small mound of land next to the

river that is higher than the 100-year flood level, and prevents the river from

bursting its banks. Nearby houses can be built on stilts to prevent flooding

from rainwater, and a floodgate beneath the stopbank can be opened to allow this

‘ponding’ to drain off into the river.

When there is no stopbank, as shown in the second diagram, there will be

nothing to stop the river from flooding. In this case, the solution is to put

buildings on stilts. The height of the stilts is measured so that the floor of

the house is 300mm above the 100-year flood level. This measurement is called

the ‘freeboard’.
