The migration of the UTHBAL hydrologic model into OpenMI

Abstract

This paper deals with the implementation and the migration into OpenMI of a monthly conceptual hydrological model, called UTHBAL. The model has been developed by Loukas et al. [2003, 2007] and now is implemented under the Microsoft Visual Studio .NET C# IDE. The integrated decision support framework provided consists of an autonomous model engine, a graph editor, an optimization/calibration server and a migration wrapper. The software allows input data polymorphism and extensibility of model integration, which is lumped in the present form. The infrastructure for incorporating various optimization libraries has also been built. On line data exchange is feasible since the model has been migrated into OpenMI through a dynamically configurable wrapper. We found that the model characteristics relevant to coupling with other hydrological models lie on the space, time, structure and optimization compatibilities. Thus other models which analyze similar phenomena can seamlessly be coupled with ours.
