要旨
In the frame of a European Interreg IIIA project between Italy and Switzerland, named "Development of a hydrological hazard prevention management system in the area of the Lake Maggiore", one of the topic is the set up of an hydrological model to simulate the interaction between artificial reservoirs and the natural rainfall--runoff mechanisms in the watershed. The hydrological model we decided to realise is a distributed, physically based and hourly one.
To accomplish the previous task a database, a statistics package and an interfaced GIS are needed; this software packages are available in the "open source" world (PostgreSQL, R and GRASS) and this was the solution we decided to adopt.
By taking advantage of the interfaces already available between these three packages the hydrological model will be implemented in an interoperable and integrated system.
