This research reviews flood risk within the Lagos area of Nigeria over the period 1968 to 2012. During this period, floods have caused harm to millions of people physically, emotionally, and economically. Arguably over this period the efforts of stakeholders to address the challenges appear to have been limited by, among other things, lack of reliable data, lack of awareness among the population affected, and lack of knowledge of flood risk mitigation. Recommendations are made for flood modeling.
