Management Accounting and Decision Making of an Organisation
This study examined the problems of urban flooding in Uyo urban Akwa Ibom State with view to identifying the types of flood prevalent in the study area, anthropogenic causes of flood and impacts associated with urban flood in uyo.
To this end, two research hypotheses were formulated, stratified random sampling was used to stratify Uyo into six (6) zones and questionnaires were administered.
Taro Yamane method for finite population was computed that 400 copies of questionnaires were administered in the study area as well as used in the analysis.
The first hypothesis was tested using Chi-square (x2) at 0.05 level of significance in order to otherwise if anthropogenic activities are responsible for the occurrence of flooding menace in the study area.
Also, the second hypothesis was tested using regression analysis to test for the impacts of urban flood on people. The analyses showed that anthropogenic activities account for the occurrence of urban flooding in the study area and urban flood do have significant impacts on people.
Based on these finding, it was recommended that among others that adequate drainage channels should be provided by government, good and adequate land-use should be encouraged, provision of adequate waste receptacles to discourage dumping of refuse in drainage channels and environmental education and awareness programms should be embarked upon at regular intervals to sensitize people on flood issues.

Urban flood is one of the hazards that affect man since time immemorial (Sada, 2004). Throughout history, nature has shown little respect for man’s unwise occupancy of watershed in humid tropical lands and elsewhere (WRC, 2009).
Flooding dates back to the Biblical days of Noah and since the pre-historical times, man has been involved in an unending struggle with natural hazards such as flood, earthquake and volcanic eruption, among others (Blazkomac, 2014).
According to Askew (2001), flooding is the most common of all environmental hazards worldwide, either induced by nature or by anthropogenic actions in the environment which has left indelible make on the landscape.
Since early times, flood has been a major aspect of man’s interaction with his environment, and scores of flood disasters are found in the traditions and literatures of many ancient people (Redijk, 2004).
In recent time, urban flood are repeatedly reported in the head lines of local national and international media because of the adverse effect it has on infrastructures. Since 1970, the world has witnessed more than ten major urban flood disaster (Allt, 2005).
In the study of Berz (2000) floods contribute about 58% of total death and 33% of economic losses and that over the period of 1988 to 1997. There was a trend of increasing number of flood events, as well as economic losses globally.
Urban flood is associated with some extreme natural events that happen on a geographical area and urban floods can have both area-wide and local origin, and are accompanied with serious environmental problems (Akintola, 2013).
Urban flood occurrence is not bound by local administrative boundaries as observed by Iyewson [2010) because storm water drainage and protection facilities are part of an urban system to channel drains. Sada (2004) opined that urban flood as an environmental hazard has caused much concern, not only to developing countries, but also to developed countries of the world.
Despite modern technology, Sada’s study further revealed that it has been impossible to completely prevent urban flood hazard. Instead man has devised various methods of controlling urban flood, though this is difficult because urban flood occurrence and their magnitude cannot be easily forecasted.
