GABCIKOV~-NAGYMAROS ITYDROELECTRIC PROJECT DESCRIBED
Prague GEODETICKY A KAkTOGRAFICKY OBZGR in Slova~ No 11, Nov 80 pp 273-279
[Article by Eng Milan Balaz, Hydroconsult, Bratislava: "Geodetic Work for the
System of Hydraulic Install.ations on the Danube"]
~ [Excerpts]
Introduction
On 30 June 1978 the agreement between the Czechoslovak Socialist Republic and
the Hungarian People's Republic to build and operate the Gabcikovo-Nagymaros
system of h~draulic installations (Fig 1) went into effect. According to this
agreement, the two parties are to build a systpm of hydraulic installations as
- a joint investment project, consisting of the Gabcikovo hydraulic installation
and "the Nagymaros hydraulic installation, which will form a unified operating
_ system of facilities, _
The composition of the main facilities in the system is as follows:
Tfie Gabcikovo installation I~as the following main components:
--the Hrusov-Dunakiliti Reservoir on a section of the Danube in Czechoslovak and
Hungarian territory;
--the Dunakiliti Dam (Fig 2) and auxiliary lock on the Hungarian side; -
--the bypass channel, i.e., a water supply and drainage channei on the Czechoslovak -
side;
--a station on the 3ypass channel at Gabcikovo ~n ~he Czechos~ovak side (Fig 3),
which will consist of a liydroelectric power station with an installed capacity of
720 megawatts, two locks, and auxiliary facilities;
- --the improved old Danube channel, a dredged and regulated channel of the Danube
in ~he joint Czechoslovak-Hungarian section.

Th~ Naomaros hydroelectric installation inc~udes the following:
' --a reservoir and the necessary protective works on a section of the Danube and on
- sections of tributaries affected by rising water levels on the Czechoslovak and
- Hungarian sides. On the Czechoslovak side these include 8 areas requiring
- protective works: the lower Ipel, the lower Hron, the Kravany, the Iza, Komarno
cit~, Komarno-Medvedov, the left bank of the Vah, the right bank of the Vah, and
the Little Danube;
--a station on the Hungarian side (Fig 4) which consists of a dam, a hydroe~.ectric
plant with an installed capacity of 158 r1W, two locks and auxiliary works;
--the deepened and regulated channel of the Danube in the Hungarian section of the
river.
~
The concept of the system of hydraulic installations includes a~oint investment
program. Detailed technical data on the system are given in the ;oint draft
agreement developed in accordance with the agreement between the Czechoslovak and
Hungarian governments.
The work on the ,joint investment project by the ~..wo sides is so organized that the
energy units will be put into operation in 1986-1990.
- The enormous size of the joint investment required that considerable geodetic work
be done on both Czechoslovak and HLngarian territory, and that the basis be laid
for wor':,ing out the joint draft agreement and for working out th~ performance plans
required for the construction itself.
Geodetic Work for the Joint Draft Agreeme*~t
It was agreed that each country would use its own coordinate system for th~
location geodetic wark:
--on the Czechoslovak side the Unified Trigonometric Survey Net�~rork (S-JTSK) will
be used;
--on the Hungarian side the Budapest Stereographic national coordinates system
will be used. The Nagymaros station is an exception, because there a local
y coordinate system supplementary to the national coordinate system will be used.
Some facilities in the system cross national boundaries (i.e., are partly in
Czechoslovakia and partly in Hungary). Accordingly it has been agreed that
positional and elevation base junction points with permanent stabilization will
be built in 5 locations, with their coordinates determined in the Czechoslovak
- and Hungarian coordinate systems and their elevations in the Bvp system. These
_ locations are: Cunovo-Ra~ka, Hrusov-Dunakiliti, Palkovicovo, Salka-Letkes, and
Lela-Letkes. At each location two points will be established on the Caechoslovak
side and two in the Hungarian side. The coordinates of the points have been
determined with a trioonometric precisj.on of the Sth ~rder, and the elevations
by the VPM metfiod.
