ABSTRACT
Flooding is seen to be a natural disaster which involves proper monitoring and control with the use of a GIS so as to prevent environmental damages, loss of human lives and other economic losses. Worldwide, there has been rapid growth in number of people killed or seriously impacted by flood disasters (UN-Water, 2011). Indeed, the amount of economic damages affects a large proportion of people in low-lying coastal zones or other areas at risk of flooding and extreme weather condition. The aim of this study is to identify flood prone areas for the purpose of planning for disaster mitigation and preparedness, using geographical Information Systems taking Uselu share road as case study. This project addresses the problem of flooding in Uselu-share with the use of remote sensing and GIS to create a flood hazard map of the area which can be used to assign remedial activities if a flood event should occur. The spatial data needed and used for this project are the satellite image of the study area which was downloaded from Google earth while the attribute data was curved out through the use of a GIS technique called the “Point Positioning “allocated in a software called The UTM geo map . This was capable of mapping out the location coordinates which was in three divisions. First coordinate was taken from a point at Rhemadok filling station , second coordinate was from “Good Samaritan junction” and third coordinate was taken from Tomeline building. All the geospatial and attribute data were then imported into the GIS software used known as Ach GIS 10.8 which resulted to the picture formed in Fig 4.1 This project demonstrates the immense potential of GIS technology in flood management. By harnessing the power of spatial data and attribute analysis, we can pave the way for a more efficient and less cumbersome approach to tackling flooding. The respondents were able to identify the causes of flooding in Uselu. They gave factors suspected as responsible for several floods in the area as well as measures adopted to stop or check the flood menace area-wide. Respondents also revealed that measures put in place to mitigate flooding were grossly inadequate and, at most times, ineffective.
