Flood is a water-related natural hazard that affects a wide range of human activities. In the recent past, many communities in Owerri have suffered losses as a result of floods. This work utilized Remote Sensing and GIS in flood risk mapping. Data on environmental indices were integrated into a GIS to perform risk/vulnerability assessment. The flood risk map produced and the ground-truthing carried out confirmed that the area with the highest flood risk is located within CBN quarters, Owala, Owaelu in Uratta, Emii and Agbala communities. While areas like Works layout, Federal Government college Teachers quarter, Imo state University Staff School and Amakohia have medium risk of flood hazard. Pointer to flood hazard mapping assessed by administering questionnaire shows that physical location, poor waste management practice, inadequate/poorly constructed roads and drainages, rainfall and poor development control practices, account for 30%, 20%, 20%, 10% and 15% respectively of the response on cause of flood. Field observation was also carried out in the area in order to assess the level of urbanization as well as the trend of development. This project was grouped into chapters chapter one talks about the introduction to the study, chapter two is the literature review, chapter three is the methodology adopted in carrying out this research work, chapter four is the discussion of the study while chapter five is the conclusion and recommendation of the study....
