Climate Change and Flood Hazard

Natural hazards are linked to climate change and they are likely to increase over the years. The vulnerability to certain natural risks such as flooding and coastal erosion can be exacerbated by climate change. The areas susceptible to the greatest increase in flooding are coastal borders which are affected by subsidence and sealevel rise, rather than fluvial flooding. The hydrologic impact of climate change can increase the occurrences of extreme hydrologic events, heavy rainfall, and droughts. There is always a human tendency to intend to control the environment, avoiding the probable natural hazards. The risk management efforts can be helpful for the society to reduce risks, take advantage of the opportunities and cope with the unexpected challenges in an integrated manner, particularly in the context of long-term risk planning and management in the environments with high rates of natural hazards. The flood risk management generally plans for increasing the existing flood protection levels to the major city areas over the next coming years. Exposure of human settlements and longlived, strategic assets such as transport and utility networks to flood risk is increasing due to climatic changes
