When considering the effects of climate change however, it is important to consider the dynamic nature of flood risks. Flood hazard mapping typically provides a ‘snapshot’ of flood risk at a given point in time. It is important to note here, that climate change must be carefully considered when implementing flood hazard mapping. They also encourage people living and working in flood-prone areas to find out more about the local flood risk and to take appropriate action (Environment Agency, 2010). It creates easily-read, rapidly-accessible charts and maps which facilitate the identification of areas at risk of flooding and also helps prioritise mitigation and response efforts (Bapulu & Sinha, 2005).įlood hazard maps are designed to increase awareness of the likelihood of flooding among the public, local authorities and other organisations. industrial activities, population density, land use) of the exposed areasįlood Hazard Mapping is a vital component for appropriate land use planning in flood-prone areas. Flood hazard assessments can be further expanded to assess specific risks, which take into consideration the socioeconomic characteristics (e.g. Measures to improve preparedness can include changes in land-use planning, implementation of specific flood-proofing measures, creation of emergency response plans, etc. Flood hazard assessments and maps typically look at the expected extent and depth of flooding in a given location, based on various scenarios (e.g. Assessment of Suitable Flood Mitigation Measures in Tbilisiįlood hazard assessment and mapping is used to identify areas at risk of flooding, and consequently to improve flood risk management and disaster preparedness.It acts as an information system to enhance our understanding and awareness of coastal risk. However, mapping of erosion risk areas may serve to achieve erosion risk reduction. As such, its primary objective is to reduce the impact of coastal flooding. Flood hazard mapping is an exercise to define those coastal areas which are at risk of flooding under extreme conditions.
