Abstract: Climate change has contributed to the increase of extreme weather events worldwide. The dominant scientific opinion on climate variability is that it will increase the frequency of heavy rainstorms, causing high devastation risk from floods for many communities (Karl et al., 2009). Therefore, only an effective flood hazard management framework can reduce an upcoming flood hazard increase. The most modern management techniques include hydro-informatic applications, such as flood forecast modeling (Golian et al., 2010), flood hazard, and flood risk mapping in order to achieve an accurate assessment of the flood zones and vulnerable areas. The aim of this paper is to compare and contrast two hydraulic models (1D and 2D) to determine which one is more suitable for flood mapping. The chosen study area is the catchment of Kimmeria. Kimmeria stream (Kydoneas) contributes to Kosynthos river in the plain section while it springs from the mountainous region of Xanthi, Greece. The total area of the watershed is 35.5 km2 while the total stream length is 6.5 km.
