Dimitrovgrad

• developed river network• 13 monitoring stations• encompasses 25% of the Juzna Morava basin by area and 32 % by discharge (very rich with water)

• 2 m3/s < Qav < 31 m3/s from Dimitrovgrad (border monitoring site) to Nis (mouth to Juzna Morava)

• low flow: cca 6 m3/s• mean high flow: cca 200 m3/s (Q100 = 988 m

3/s)

Nisava: Hydrogelogy

Velika Morava Basin comprise parts of the several Hydrogeological Units:

•Central Serbia: The most important are alluvial aquifers (exposed to highly intensive anthropogenic impacts) of the Velika, Južna and Zapadna Morava. The Velika Morava alluvium is the main water-bearing medium, comprised of 6-60 m thick sandy-gravelly sediments. The major Neogene aquifers are in the Leskovac and Jagodina-Paraćin basins. The extent of the karstic aquifers is limited.

Eastern Serbia: Large alluvial aquifers are rare (the Nišava and Timok basins). Most important is the artificially-recharged Mediana water source in the City of Niš, with yield of some 600 l/s.Thelarge number of karstic springs, 16 of which have a minimum Q > 100 l/s. Neogene aquifers in isolated lacustrine basins are less significant.

Nisava: WFD implementationTransboundary GW bodies,GW use

In 2007 as a part of UN ECE “First Assesment of rivers , lakes and groundwaters”, possible TB GWs identified between Serbia and Bulgaria (No. 34 “Stara planina/Salasha Montana”Transboundary Groundwaters).

In the Velika Morava Basin, 3 GW bodies are part of this : Vidlič, Stara planina and Nišava 2.

No transboundary impact observed.

Nisava: WFD implementationSurface waters

Activities performed so far

(rivers with catcment area > 100 km2)

•identification of surface waters categories

•river typology

•delineation of river water bodies

•provisional identification of HMWB

•identification of pressures

•risk assessment for large rivers (Nisava)

Nisava: WFD implementationSurface waters bodies

Nisava: main pressures

HYMO:

• large dams (Zavoj , Sukovo)

• number of small HP plants

• flood protection structures and river training works (mainly on the Nisava River)

Point sources:

• municipal, industrial sources

Risk assessment (only for the Nisava river)

• 2 of 3 water bodies possibly at risk from organic pollution, hazardous substances and nutrients

Nisava: transboundaryimpact

• river engineering works in BG

• affected rivers: Nisava, Visocica

• pressure: water abstraction – diverting to another catcment

• impact: decrease of mean and low flows at entrance to RS

Nisava: status, measures

• No status assessment so far in Serbia

• List of measures only at the Danube river basin level(in favorable conditions, improvement of the wastewater treatment issues in the city of Nis can be expected)

Thanks for your attention…
