Be aware that the hazard level provided by the tool should be considered a first estimate of flood hazard. The objective of the location assessment is to gain a greater understanding of the likely flood hazard at your location, through the interpretation of the local landscape. If they do, it would then be necessary to identify whether the location of interest is situated in an area that may become flooded, usually by identifying whether the area is located within a natural floodplain (see Guidelines for Environment Risk Assessment and Management). To further define potential flood risk, a local assessment should be undertaken to identify whether any sources of flooding exist (rivers/streams). Flood hazard can vary dramatically over short distances, depending on factors such as local topography and distance to waterways. Since flooding is a very local phenomenon, the hazard information provided by this tool should be considered the preliminary action in defining river flood hazard level. Before committing significant resources to this issue, a study of the surrounding landscape can help you assess whether more detailed assessment and/or intervention should be considered. LOCATION ASSESSMENT: The high-level information available in this tool may indicate the presence of river flood hazard in your project area. It would be prudent to design projects in this area to be robust to river flood hazard in the long-term. The present hazard level is expected to increase in the future due to the effects of climate change. Please note that these recommendations are generic and not project-specific.Ĭlimate change impacts: High confidence in more frequent and intense precipitation days in winter and an increase in the number of extreme rainfall events. Please see 'Urban Flood' for consideration of urban surface and river flooding.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. Surface flood hazard in urban and rural areas is not included in this hazard classification, and may also be possible in this location. Project planning decisions, project design, and construction methods must take into account the level of river flood hazard. This means that there is a chance of more than 20% that potentially damaging and life-threatening river floods occur in the coming 10 years. In the area you have selected (Dordogne) river flood hazard is classified as medium based on modeled flood information currently available to this tool.
