3 The enviroGRIDS project  FP7 (Theme 6:environment). April 2009 – March 2013, 1403 man-months, €8.1 mio. tot. budget, €6.2 mio. EC contribution Overarching objectives  data gap analysis  spatially explicit regional scenarios of development  develop early warning and decision support tools at regional, national and local levels  Build capacities in the Black Sea region to enhance data interoperability, by promoting open standards (ISO and OGC)  large scale, high resolution distributed hydrologic model of the Black Sea watershed  a Grid-enabled Spatial Data Infrastructure (SDI)

6 Catchment hydrological model

7 Typical SWAT user arcGIS (Windows) Text files

8 Split large SWAT models at sub-basin level, compute them separately, merge individual outputs from each sub-basin, and route the outputs through the river network SWAT gridification

9 Displaying SWAT results BAsin Scale HYdrological Toolkit (BASHYT) The aim is to have BASHYT communicate with the grid It is currently optimized for a one basin scenario
