Incorporation of Models

The creation of an operational and integrated comprehensive Decision Support System (DSS) for optimal watershed management especially of transboundary catchments is the main outcome of the European TRANSCAT project. The implementation of different models and developed decision-oriented applications applied and tested under different conditions gives rise to a contemporary tool for the creation of new transboundary management options.
Integrated River Basin management needs to incorporate all the relevant sectors that interact within water management. TRANSCAT DSS comprises five major subsystems that are concerned with data management, modelling, mapping and spatial analysis (geoprocessing), DSS functionality and module for user management:
The five subsystems cover the essential functionalities that should be offered to the user.
The infrastructure of the TRANSCAT DSS is created as distributed, consisting from decision analytic and auxiliary applications, modelling subsystems, and core servers is based on the principle of web services.
The operation of the TRANSCAT DSS is illustrated on the Bulgarian-Greek Mesta/Nestos transboundary river.
The multiple modeling tools provide the user with the possibility of selection according to the needs of the area and the data available. The connection between strategic decision tools and modeling support through the core system is a way to meet the need of integration of different tools in water management. Hence, based on modeling tools predictions (rainfall-runoff modeling, ground water flow, water quality models) and indicators stored in an integrated data base the user can apply a range of decision support tools (MULINO, Mediator etc) that will assist with evaluation of different scenarios/choices and the design of decision making procedures.
The co-existence of such different tools and functions is a major achievement in the sector of water management. The manager/user can store data, run hydrologic models and evaluate possible scenarios and even apply group-decision making techniques if required, while visualizing geographic information through the mapping sub-system. This approach has provided a complete scientific tool to support integrated water management, whose elements can be used in a variety of configurations.
