Abstract
Flood risks are considered as one of the most devastating natural disasters. Presently, flooding occurs in all the ecological zones in Nigeria which has been linked to global warming. In Lagos Megacity, the incidence of flooding is now a reoccurring decimal which is only an indication of the failure of the existing mechanism for flood risk reduction. Knowledge of public perception of flood risk is considered a crucial element for a proactive preparedness for flood risk reduction. This study is aimed at gaining insight into the public perception of flood risks for proactive flood risks preparedness among residents in flood prone areas in Lagos megacity, Nigeria. The survey research design was utilized. Data were collected by questionnaire from residents of flood prone neighbourhoods in the city. The results show high awareness of flood risks among respondents that have experienced flooding previously than respondents that have not experienced flooding in the past. It also reveals poor preparedness among respondents that have not experienced flooding. The paper calls for public awareness creation among residents in flood prone areas of the city as a strategy to promote preparedness for flood disaster risks reduction in the city.
Sandy foreshores play an important role in flood risk reduction in areas near seacoasts, estuaries and lakes. The morphodynamics of sandy foreshores or beaches in lakes, known as low-energy, non-tidal environments, have not been studied as extensively as open coasts. The goal of this research is to understand the relation between hydrodynamics and morphology on sandy lake beaches. At our four study sites, a sub aqueous horizontal platform evolved of which the elevation stabilizes over time. We conclude that the eventual elevation of these platforms is located at the depth of closure.
