The aim of this project is to create a flooding model able to predict where a flooding event will take place 3-7 days in advance. The model uses as input free accessible data, giving the possibility of being adapted to any region that can only benefit from basic data, like Digital Elevation model, information regarding the soils and land cover. The model also uses free meteorological data that is retrieved in real time. The results are presented using a Web GIS component and displaying the results on top of a map, giving the user a clean and intuitive interface for observing the results. The model is not by any means a very precise tool for flood modelling, working as a prime warning system for future flooding events pinpointing the area in danger, therefore the results need to be considered with caution.
