Abstract

This study assesses the flood vulnerability, land use relationship and topographic information of the Ibadan metropolis consisting of eleven local Government areas namely; Ibadan North, Ibadan North East, Ibadan North West, Ibadan South East, Ibadan South West, Akinyele, Egbeda, Ido, Lagelu, Ona-Ara, Oluyole of Oyo State, Nigeria using geospatial analysis with the objectives of analysing the areas vulnerable to flood, land use/land cover, determine the topography of water flow and identifying the watershed of Ibadan.  Geology Map was used in determining areas whose surfaces will be likely to retain surface runoff and hence cause secondary flooding. Land Use Map of Ibadan was derived from the reclassification of a 2018 medium resolution landsat satellite image of Nigeria. The results showed that 82.75% are vulnerable to flood. Only the highly developed and commercialized area shows presence of pavements and   …..
