The diagrams below show how houses can be protected in areas which are prone to flooding. Write a report for a university, lecturer describing the information shown below. Summarise the information by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

These diagrams depict the ways which can be used by people to protect houses against

floods

in some regions.

Overall

, it can be seen that buildings were constructed on columns which made them above the ground

level

.

According to

what is shown, a

stopbank

was not set up, because the houses were established at a higher

level

above the floor, at 300 mm.

Hence

, if

floods

came, they would have gone easily under homes without striking them. building the

stopbank

was very crucial, as it played a pivotal role in the protection of houses against

floods

, where it collected water inside it, so the pressure of the

floods

was reduced and their harmful effects could be prevented.

Also

, the

stopbank

exerted positive effects, particularly when the

level

of flood elevated which became nearly double after 100 years.

To sum up

, we could say that when the

stopbank

was not built the

level

of raised buildings above the ground was approximately twice that of the elevated buildings where a

stopbank

was constructed.
