Abstract-Topics such as the sustainability and vulnerability of land management practices on water quality and quantity are very important in these days both for decision makers and for citizens. The enviroGRIDS FP7 project addresses some of these topics in the Black Sea Catchment area. One of the software tools developed in this project is gSWAT. It allows the calibration of SWAT hydrological models in a flexible development environment and uses distributed computational infrastructures to speedup the simulations. The development of SWAT (Soil Water Assessment Tool) hydrological models is a well-known procedure for the hydrological specialists and this paper highlights, from the end-users point of view, the scenarios related with the calibration procedures available in the gSWAT application.

“…The user may enter data and metadata, visualize, modify, update, and remove spatial data from data repositories. The hydrological model oriented platforms and applications, gSWAT (Grid based SWAT) [4] and gSWATSim (gSWAT Services Implementation) [5], support the specialists on Grid based hydrological model configuration, scenario and model development, model calibration, and scenario execution. Using the GreenLand satellite data processing platform and application the specialists may process satellite data and images in order to search for relevant information (e.g.…”

Abstract-The Black Sea Catchment area is well known for subjects such as ecologically unsustainable development or inadequate resource management. The EnviroGRIDS project addresses these issues by using emerging information technologies. The enviroGRIDS Web Portal allows the users to access the geospatial functionality given by Web infrastructure, and to high power computation resources given by Grid infrastructure. The Black Sea Catchment Observation System portal provides a single point of access to the enviroGRIDS applications and tools. Both the vertical and horizontal interoperability are available between the platforms and applications throughout the portal. The horizontal interoperability is accomplished through services, meaning the applications are working together by the exposed services. The vertical interoperability is supported by the communication between the layers of end user applications, Web infrastructure, and Grid infrastructure. The basic solution of interoperability is accomplished by services, messages, and data. The paper highlights the solutions developed by the Black Sea Catchment Observation System portal to support various types of interoperability between the modules of geospatial data management, hydrological model calibration and running, satellite image processing, spatial data visualization, and virtual training center.

Abstract. 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.
