In this thesis the main goal was to assess the Flood Risk of the area of Malia, by using the Geographical Information Systems software (GIS). Malia is a coastal town, which is located 36 kilometers east of Iraklion in Crete, being a borough of the municipality of Hersonissos. In order to implement this study, rain data was utilized. These data are collected from four meteorological stations which are positioned around the field. Simultaneously, importing maps, which contains the geology and the contour lines of Crete, in the GIS software was an obligatory prerequisite in order to conduct the study.The factors which facilitate the assessment of the Flood Risk are six. More specifically, these factors are: the Altitude, Slope, Flow Accumulation, Hydrogeology, Land Use, and the Spatial Distribution of Rainfall Intensity. The aforementioned factors were quantified on a same-basis scale by creating six raster maps. The ideology behind this quantification, is that each and every map includes the numbers of 1, 2, 5, 8 and 10, which corresponds to Very Low, Low, Moderate, High and Very High flood risk. Ultimately, these six maps were combined, producing one final map which depicts the overall Flood Risk, concerning the study area of Malia.As a result, by utilizing the GIS software, the current situation regarding the Flood Risk of Malia has been specified. These results establish that, the town of Malia as a whole, is characterized by Moderate Flood Risk, which leads to the inference that the area needs distinct attention, especially taking into account the constantly accretive climate change which is developing through the years.
