Software integration for flood management

The following article describes a file based integration used to integrate the hydrological (0D) HEC-HMS, the 1D hydraulic HEC-RAS and 2D hydraulic Sobek. Such integration allowed to run the models one after the other as a single one, taking the output from one model as the input for the next one. Furthermore, such integration not only allowed to overcome model limitations, but also opened new opportunities such as an online application where the user is able to execute the models inside a website and get the results. File based integration was easily coupled with new application as Google Earth in order to produce flood maps and animations easily accessed by the common user.
