Abstract
Flooding is one of the most dangerous natural hazards which causes economic losses and death globally. In the last three decades,there has been a rise in flooding events globally. Furthermore, it has been projected that the occurrence of flooding is expectedto rise due to urbanization, haphazard development, rise in precipitation and deforestation. Floods in Kumasi have become aperennial phenomenon. This has caused significant damages to properties and financial losses. The research utilized a geographicinformation system through a modelling approach to map flood hazard and assess risk in Kumasi. The results reveal that inthe study, 53% of the entire area was found to be highly susceptible to flooding. In addition, 35% of the population are athigh risk of flooding. The high-risk zone was found to cover the north – western and the city centre. Also, the city centre wasidentified to be highly prone to flooding and also floods are likely to occur in the rainy season. Moreover, Bantama and Subinwere identified to be at more risk of flooding as compared to the other sub- metros. The results from the flood hazard map andthe risk map suggest flooding in Kumasi is of critical concern and thus flood management strategies need to be implemented.
