Description

This paper describes the structure of JGrass-NewAge: a system for hydrological forecasting and management at the basin scale. It is based on the Geographic Information System uDig and composed of two parts: (i) the system for data and result visualization based on JGrass and (ii) the modelling components. The latter are implemented as OMS3 components, which can be connected or excluded at runtime, according to the needs of who runs the model, and work seamlessly inside the uDig ver.1.3.1 spatial toolbox. Compared to other models which are built upon monolithic code, JGrass-NewAge allows for having multiple modelling solutions for the same process, provided they share the same input and outputs. Since sound hydrological modelling requires a proper definition of a digital watershed model, this paper presents and discusses an implementation based on uDig .
