Grid Based Services and Tools for Hydrological Model Processing and Visualization

Different scenarios based on environmental changes and water quality models could be used to assess the sustainability and vulnerability of a particular geographical region. The gSWAT and BASHYT platforms provide services and tools supporting the calibration, execution and visualization of the SWAT models. The paper presents the experiments on the execution of different scenarios based on calibrated SWAT model over the Grid infrastructure. Based on the requirements for the SWAT models, lots of input and output data, the high number of simulations that must be performed in the calibration process, the Grid could offer both the storing and execution solutions. This paper presents the interoperability between gSWAT and BASHYT platforms highlighting the architectural components and presenting some test cases to assess the system performances. The research work is supported by the 4-years FP7 Project called Enviro GRIDS - Black Sea Catchment Observation and Assessment System supporting Sustainable Development (http://www.envirogrids.net/) co founded by the European Commission.
