Abstract Flooding is one of the major problems which demands urgent and effective management, most especially in mega cities like Lagos. In this study, the emphasis is on a flood forecasting approach using the Gumbel Type 1 extreme distribution, in order to establish a lead-time preparation for flood planning and management. Also, a flood-prone area map was generated for the area using Geographical Information System (GIS) techniques for flood mitigation action.

Key words extreme-value analyses; flood; flood mitigation measures; probable maximum rainfall; urbanization
