In the area you have selected (Sao Tome and Principe) urban flood hazard is classified as low based on modeled flood information currently available to this tool. This means that there is a chance of more than 10% that potentially damaging and life-threatening urban floods occur in the coming 10 years. Project planning decisions, project design, and construction methods should take into account the level of urban flood hazard. The following is a list of recommendations that could be followed in different phases of the project to help reduce the risk to your project. Please note that these recommendations are generic and not project-specific.
Climate change impacts: Model projections are inconsistent in their estimates of changes in rainfall. The present hazard level may increase in the future due to the effects of climate change. It would be prudent to design projects in this area to be robust to river flood hazard in the long-term.
