A total of 573 respondents were randomly selected across the 13flood zones that make up Port-Harcourt to elicit information on household perceptions of socio-economic impact of flood disaster in the study area.Findings indicated that although high awareness level was demonstrated by respondents, they were not properly informed of likely flood occurrence earlier enough.It was revealed through findings that perceived natural causes of flood occurrence were attributed to increased precipitation, sea level rise and low-lying terrain. Anthropogenic factors include building in flood prone areas such as along rivers, flood plains and wetlands, blocked drainage system and dam failure. There were significant variations in the household perceived socio-economic impact such as disruption of trading activities (F=12.136, p<0.05), disruption of farming activities (F= 31.144,p<0.05) constraint to vehicular and pedestrian movement (F=10.32, p<0.05), scarcity of portable water (F=12.11, p<0.05), widespread of disease epidemic (F=13.996, p<0.05), reduction in the value of landed property(F=13.10, p<0.05), as well as disturbing education (F=12.4 p<0.05)across the 13 zones. Victims lacked institutional support and government interventions were limitedscope. Flood adverse effects can however be reduced by creating more effective early warning and awareness outreach across the study area, avoiding building in flood prone locations and improving resilience capacity of the vulnerable populations. In addition, government should formulate policies that will reduce the vulnerability of people living in flood-prone areas.uhh
