The aim of this assignment is to give background information about flooding in South Africa. These would be carried out through the means of research on journal entries, web research and different literatures. The nature of flooding, the main causes of flooding, the effect of development of flooding hazards and the effect of the economic status of people regarding flooding hazards will be taken into consideration.
