Mapping the Danube River and Impacts of the
Gabcikovo Water Project by Kristi Shaw
Data Sources
• Digital Chart of the World• University of New Hampshire/GRDC Global
Composite Runoff Data Set (v 1.0)– Basin Data
• Potential Simulated Topological Networks (STN-30P)
• Global River Discharge Database (RivDis 1.1)• USGS EROS Data Center Hydro1K Elevation
Derivative Database• Europe Atlas CD (2000)
Digital Elevation Model(taken from USGS Hydro1-
Europe Dataset)
Mapping the Danube River using Arc View 3.2
• Selected countries in Digital Chart of the World
• Ponet (polygon), Dnnet (arc), Dnpoint converted to shapefiles
• Category: Projections of the World
• Type: Geographic
• Map Units: Decimal Degrees
Comparison of DCW Basin with UNH/GRDC STN-30p Basin
• UNH/GRDC Potential Simulated Topological Networks (30 minute spatial grid system) and UNH/GRDC Composite Runoff Fields
• Danube river and tributaries shapefiles provided by Europe Atlas CD (special thanks to Mustafa Akcay)

Selecting for the Danube River Network
• Tributaries: Inn, Morava, Mura, Drava, Sava, Tisza, Mures, Olt, Siret, Prut
• Removed all unrelated rivers using
start editing tool and
• Using Geoprocessing extension
to merge river themes from each country into one theme
Network Connectivity using Arc Info 8.0
• Created new personal geodatabase and then followed with new feature dataset (selecting Geographic Coordinates in GCS_WGS_1984 projections)
• Coverage to geodatabase from Merge1.shp (danube1) adding two sinks in ArcMap• Geometric Network Wizard (danube1, outlet (sink))• Danubegeo_junctions created

Geographic Projection of Danube River and River Stations
• Projection Utility Wizard (Geographic Projection with GCS North American 1927 Datum)
• Selected Danube Stations (points) from UNH RivDis 1.1– did not coincide with river (line)

Gabcikovo Water Project
Approximately 100 miles
Original Danube RiverDanube River (with Gabcikovo Water Project)
Opposing Views
• Hungary– Gabcikovo would adversely
affect water quality increasing deposits of polluted clay in reduced flow regions
– Lowering of water table
– Danube villages flooded
– Ceased involvement 1989
– Change international boundary (trading tariffs(?))
• Slovakia– Guarantee 95% minimum
flow rate along original Danube
– Hydroelectric-power station provided nearly 2 billion KWH electrical energy during first year
– Replenish flow in river reaches near reservoir
– Significant financial investment
Alternative C (I)
• After discussion and deliberation, Alternative C began construction in July 1991
Alternative C (II)
• Reservoir• Connection
Dike (Dam)• Headrace
Canal• Gabcikovo
River Step (hydroelectric power station and two navigation locks
Gabcikovo Water Project
– Reduced to approximately 30 miles
Gabcikovo Structure
Opposing Perspectives
Limiting Factors
• Flow Data unavailable for post-1992 (to compare effects of the Gabcikovo project)
• Lack of scientific evidence available regarding effects of the Gabcikovo
• Language barrier
• Data available often did not include reference datum and/or projection
