MODELLING FLOOD PRONE AREAS IN AKWA IBOM STATE, SOUTHERN NIGERIA USING GIS TECHNIQUES | Journal ...

The goal of this research was to model flood-prone areas in Akwa Ibom State. In the research area, some of the major components of floods were found. The following parameters were calculated: Euclidean distance, elevation, aspect, slope, vegetation, and soil layers. A final flood-prone layer was constructed, as well as a GIS data base containing all of the layers. The flood prone layer was created using data on Euclidean distance from the ocean and river, elevation, aspect, slope, vegetation, and soil. The data was prioritised and integrated using ARCMAP 9.2's Single Output Map Algebra function to construct the different output layers, which were classified into three categories: low, moderate, and high flooding. The research area's flood output layer revealed that flooding was low in about 1,026.4 km2 (about six Local Government Areas), moderate in approximately 4,243 km2 (about twenty one Local Government Areas), and high in approximately 1,574 km2 (about five Local Government Areas). As a result, it was proposed that attention be given to minimising flooding hotspot areas by identifying techniques that the government may utilise to prevent flooding. This requires a greater knowledge of social preparation as well as adaption constraints and impediments.
