| Zusammenfassung |
| Nowadays the decision makers but also citizens are concerning with the sustainability and
vulnerability of land management practices on various aspects and in particular on water
quality and quantity in complex watersheds. The Black Sea Catchment is an important
watershed in the Central and East Europe. In the FP7 project enviroGRIDS [1] was developed
a Web Portal that incorporates different tools and applications focused on geospatial data
management, hydrologic model calibration, execution and visualization and training
activities.
This presentation highlights, from the end-user point of view, the scenario related with
hydrological models using the tools and applications available in the enviroGRIDS Web
Portal [2]. The development of SWAT (Soil Water Assessment Tool) hydrological models is a
well known procedure for the hydrological specialists [3]. Starting from the primary data
(information related to weather, soil properties, topography, vegetation, and land management
practices of the particular watershed) that are used to develop SWAT hydrological models, to
specific reports, about the water quality in the studied watershed, the hydrological
specialist will use different applications available in the enviroGRIDS portal. The
tools and applications available through the enviroGRIDS portal are not dealing
with the building up of the SWAT hydrological models. They are mainly focused
on:
calibration procedure (gSWAT [4]) - uses the GRID computational infrastructure
to speed-up the calibration process;
development of specific scenarios (BASHYT [5]) – starts from an already
calibrated SWAT hydrological model and defines new scenarios;
execution of scenarios (gSWATSim [6]) – executes the scenarios exported from
BASHYT;
visualization (BASHYT) – displays charts, tables and maps.
Each application is built-up as a stack of functional layers. We combine different layers of
applications by vertical interoperability in order to build the desired complex functionality.
On the other hand, the applications can collaborate at the same architectural levels,
which represent the horizontal interoperability. Both the horizontal and vertical
interoperability is accomplished by services and by exchanging data. The calibration
procedure requires huge computational resources, which are provided by the Grid
infrastructure. On the other hand the scenario development through BASHYT requires a
flexible way of interaction with the SWAT model in order to easily change the input
model.
The large user community of SWAT from the enviroGRIDS consortium or outside may
greatly benefit from tools and applications related with the calibration process, scenario
development and execution from the enviroGRIDS portal.
