The regular users visualize the reports generated by the specialists as results of executing environmental scenarios. The input data for the reports are built up by the specialists by running hydrological models of the Black Sea catchment area and by processing related satellite data. All data sets required building up the hydrological models, environmental scenarios, and spatial models are provided and entered into the system by the data providers.
EnviroGRIDS functionality gathers services provided by various technologies such as SWAT related modules , Collaborative Working Environment (CWE) , Uniform Resource Management (URM) , gProcess and ESIP Platforms , and experience on other research projects like GiSHEO, SEE-GRID-SCI, and EGEE.
EnviroGRID system is developed on the gLite middleware available on EGEE, SEE-GRID and enviroGRIDS VO infrastructures.

EnviroGRIDS (Black Sea Catchment Observation and Assessment System supporting Sustainable Development)  is a 4-years FP7 Project aiming to address the subjects of ecologically unsustainable development and inadequate resource management. The project develops a Spatial Data Infrastructure of the Black Sea Catchment region. The geospatial technologies offer very specialized functionality for Earth Science oriented applications as well as the Grid oriented technology that is able to support distributed and parallel processing. One challenge of the enviroGRIDS project is the interoperability between geospatial and Grid infrastructures by providing extended features of the both technologies. The enviroGRIDS system resources are accessible to the large community of users through the BSC-OS Portal that provides Web applications for data management, hydrologic models calibration and execution, satellite image processing, report generation and visualization, and virtual training center.
Description of the work
The portal publishes through the Web applications the geospatial functionality provided through Web technologies and the high power computation supported by the Grid technologies. There are five categories of users such as data providers, earth science specialists, decision makers, citizens, and system administrators.
The portal consists of a set of Web applications through which the users access the system resources such as spatial data, hydrologic models, environmental scenarios, data processing tools, visualization facilities, environmental reports, and training materials.
The main user application categories provided by the portal are Data management – provide the user with spatial data management and operations. The user may enter data and metadata, visualize, modify, update, and remove spatial data from the data repositories; Hydrologic model management – provide the Earth Science specialists with hydrologic model configuration, scenario and model development, model calibration and scenario running. One of the water quality models that will be used is SWAT (Soil Water Assessment Tool) . SWAT is a model designed to estimate impacts of land management practices on water quantity and quality in complex watersheds. The SWAT model requires specific information about weather, soil properties, topography, vegetation, and land management practices of the watershed.; Satellite data processing – the specialist may process satellite data and images in order to search for relevant information (e.g. land cover, vegetation, water, soil composition, etc); Data visualization and report – the specialists visualize various spatial data in different formats and views and compose environmental reports for decision makers and citizens; Decision maker and citizen application – provide the decision makers with the interactive and graphical tools to access the private environmental reports. The user may visualize data that make possible statistical analysis and predictions.
The presentation mainly highlights the issues and the experiments on interoperability between geospatial and Grid platforms in order to support high power computation requirement applications. The SWAT model covers the huge area of the Black Sea Catchment region. It is a quite complex model that requires the high performance resources of the Grid.
The experiments have revealed the potential of the Grid related technologies. New user interaction techniques and platform interoperability are the main directions of the future research work.
