data sources
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)
mapping the danube river using arc view 3 2
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
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
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
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
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

Gabcikovo Water Project

Approximately 100 miles

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

Opposing Views
alternative c i
Alternative C (I)
  • After discussion and deliberation, Alternative C began construction in July 1991
alternative c ii
Alternative C (II)
  • Reservoir
  • Connection Dike (Dam)
  • Headrace Canal
  • Gabcikovo River Step (hydroelectric power station and two navigation locks
gabcikovo water project1
Gabcikovo Water Project
  • Reduced to approximately 30 miles
limiting factors
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
