摘要

Floods are natural hazards with serious negative effects for the people, community, and economy. Advances in technology provide assessment and prediction of risk flooding, which is a complex problem dependent on many factors. Here, a risk flood assessment approach using the Analytic Hierarchy Process (AHP) for the Arachthos River, Greece is presented. It is based on real-time data deriving from various sources such as meteorological stations and water level sensors. The proposed risk flood assessment system is based on seven factors: the sum of one day and three-day rainfall, the elevation, the land use, the slope, the water level, and the differential river height. It considers the catchment area of the Arachthos River as a focus area and produces a hazard assessment map based on AHP method. The hazard maps are useful for civil protection and local authorities, they provide visualized warning on possible catastrophic events, identify areas with a high-risk flood likelihood and they include useful information and increase the knowledge of local authorities and relevant stakeholders.
