| Zusammenfassung |
| The calibration and execution of large hydrological models, such as SWAT
(soil and water assessment tool), developed for large areas, high resolution,
and huge input data, need not only quite a long execution time but also high
computation resources. SWAT hydrological model supports studies and
predictions of the impact of land management practices on water, sediment,
and agricultural chemical yields in complex watersheds. The paper presents
the gSWAT application as a web practical solution for environmental
specialists to calibrate extensive hydrological models and to run scenarios,
by hiding the complex control of processes and heterogeneous resources across
the grid based high computation infrastructure. The paper highlights the
basic functionalities of the gSWAT platform, and the features of the
graphical user interface. The presentation is concerned with the development of
working sessions, interactive control of calibration, direct and basic
editing of parameters, process monitoring, and graphical and interactive
visualization of the results. The experiments performed on different SWAT
models and the obtained results argue the benefits brought by the grid
parallel and distributed environment as a solution for the processing
platform. All the instances of SWAT models used in the reported experiments
have been developed through the enviroGRIDS project, targeting the Black Sea
catchment area. |
