ABSTRACT: The study assessed the causes of 2012 flood in Aguleri and Umuleri in Anambra East Local Government Area. In doing this, questionnaire was administered randomly to the residents. The data generated were analyzed using frequency/percentage tabulation and Mann- Whitney U-Test statistical techniques. The following hypothesis was tested: (1) there is no significant difference between the causative factors of 2012 floods in the two communities. The results showed that there is no serious variation between the causes of 2012 flood in the two communities. In addition, the result also proved that anthropogenic activities induced the 2012 flood in the community. Consequent upon the findings, the study recommended that there should be flood hazard mapping in order to ascertain areas prone to flooding, so as to reduce the occurrence of flood in the area. It further recommended that the river channels in the area be constantly dredged from time to time so as to increase their capacity for retaining water. Moreover, it recommended that the inhabitants of the area be enlightened on the causes of flood. Finally, it recommended that environmental laws, especially those relating to flood occurrence and management, and land-use be enforced. In addition, areas of future research should be: (1) to ascertain the after-effect (post effect) of flooding on agriculture in the area; and (2) to obtain a flood hazard map for the entire Anambra State, especially the Anambra East Local Government Area, so as to know the areas prone to flooding, and to adopt adequate flood management techniques.

This is especially the case in most wetlands of the world. The reason of this is the general rise in sea level globally, due to global warming as well as the saturated nature of the wetlands in the Riverine areas. Periodic floods occur on many rivers, forming a surrounding region known as flood plain. Rivers overflow for reasons like excess rainfall. In extreme cases flooding may cause a loss of lives. As noted by Adeleye and Rustum (2011) torrential rains made rivers to overflow their banks and caused mud houses to collapse and also washed away livestock. In some places and cases, flooding has damaged bridges and caused overflow of dams, submergence of buildings, displacement of people from their homes, loss of people’s valuables. The economy of a place can also be severely affected by flooding. Businesses may lose stock, patronage, data and productivity
