Understanding long-term flood risk is a crucial aspect of effective flood risk management and its impact on surveying decisions. Long-term flood risk refers to the cumulative probability of flooding over an extended period, typically spanning decades or even centuries [1]. This type of risk is often assessed using statistical models and historical data to predict future flood events [2].
Flood Risk and Its Definition
Flood risk is the likelihood of a flood occurring at a specific location within a given timeframe [3]. It is a complex and dynamic concept that is influenced by various factors, including climate change, sea-level rise, and urbanization [4]. Climate change is expected to lead to more frequent and severe flooding due to the increased frequency and intensity of extreme weather events [5]. Sea-level rise, on the other hand, is expected to increase the risk of coastal flooding and erosion [6]. Urbanization can also increase flood risk due to the increased impermeability of urban surfaces and the heightened concentration of people and property in flood-prone areas [7].
Long-Term Flood Risk and Its Impact on Planning Decisions
Understanding long-term flood risk is essential for making informed decisions about land use and development [8]. Long-term flood risk can significantly impact land valuation and property values, with flood-prone areas often having lower property values due to increased flood risk and potential damage [9]. Therefore, surveyors must consider flood risk when evaluating land values and advising clients on investment decisions [10].
According to the European Flood Risk Management Strategy, long-term flood risk management requires a proactive and multi-faceted approach [11]. This can involve implementing flood mitigation strategies, such as levees, floodwalls, and flood-proofing structures [12]. Early warning systems and emergency preparedness plans can also help to minimize the impact of flooding on people and property [13].
In conclusion, understanding long-term flood risk is essential for effective flood risk management and its impact on surveying decisions. It requires a proactive and multi-faceted approach, involving the consideration of various factors, including climate change, sea-level rise, and urbanization.
