1. J-HYDRO: AN IMPLEMENTATION OF THE DIGITAL WATERSHED Silvia Franceschi Andrea Antonello Riccardo Rigon FOSS4G2008 Cape Town September 2008

2. DEFINITION OF DIGITAL WATERSHED Digital watershed is a large system which uses the modern technologies to capture, store, manage, process and analyze all the information related to a watershed (data and models), and on the bases of these, then develops a comprehensive decision-making system to optimize the management of the watershed (Zhang, Wang and Shibasaki).

7. THEMATIC APPLICATION SUBSYSTEMS The thematic application subsystem is the applied layer of the digital watershed. In a watershed, there are always many administrative and professional departments in different fields (hydrology, natural resource and environment), that have their own corresponding requirements for decision-making support systems. Different thematic application subsystems should be developed for these professional departments in order to provide thematic application services .

10. J-HYDRO J-Hydro was first implemented for the administration authority of the Adige basin (the second biggest Italian river) as part of a project studying the water resources management, particularly in case of water scarcity .
