Abstract

The hazard and damage caused by flooding cannot be overemphasized in terms of loss of life, property, displacement of people and disruption of socio-economic activities as well as the loss of valuable agricultural land due to the problems associated with flood plains such as excessive rainfall and dam failures. Several areas along the coast of the Atlantic Ocean and along Major River valleys are affected by floods every year of which, urban flooding is gradually becoming a serious ecological problem in Nigeria. To gain better understanding of the flood problem especially for planning purposes, flood hazard maps are often required. A combination of data records on flood plains such as land use/cover, river/flood stage, and digital elevation models are used to predict future flood stages and likely impacts. Geographical Information System (GIS) and results of analysis of flood stage data using a combination of digital elevation model and land use/land cover data as well as rainfall data were used to map out the areas that are prone to flood hazard and forecast flood in Kaduna Metropolis. Areas under high risk due to flooding were also determined. The study revealed that most of the areas lying close to the River Kaduna's flood plain are under severe threat to flooding and some suggestions are proffered.
