And it takes 3 - 5days for the flood water to recede depending on the magnitude of event and receding factors in different areas. Factors other than rainfall identified to substantially influenced flooding in the study area are: Lack of and poor drainage networks, dumping of wastes/refuse in drainage and water channels, topographic characteristics, overflowing of river banks, low infiltration due to high water table and degree of built or up areas leading to increased runoffs, and climate change. Despite the flood hazards, occupants in flood prone have remained on the basis of having no alternative, cultural ethnic affinity, family home place where parent were buried, used to flooding as the whole area suffers from flooding, nature of occupation, and cheaper houses to rent.
