The Nisava river water quality as the indicator of the sustainable development of the city of Nis

Abstract

The Nišava river has a great importance for the sustainable development of the city of Niš. From the Mediana spring, which is on the bank of the Nišava, the city of Niš satisfies around 30% of its water demand. The aim of this paper is to, on the basis of the analysis of several tens of parameters of water quality; determine whether the Nišava river is a limiting factor to the sustainable development of the city of Niš. For this purpose the data of Public Utility Company Naissus have been used, as it collects daily samples of the Nišava river water. The number of conducted analyses, depending on the water quality parameters, varies from 1 to 1,240. The obtained results, which have been presented in detail in the paper, indicate that a great majority of analyses, of almost all the water quality parameters, is within predicted range. At the end of the paper, certain measures have been proposed, which should contribute to the sustainable development of Niš in this field.

Trend analysis of water quality parameters for the Nisava river

“…In the present study, series of daily water temperature (T, o C), electrical conductivity (EC, μS/cm), pH, biochemical oxygen demand (BOD, mg/l), dissolved oxygen (DO, mg/l), total hardness ( o dH), chlorides (Cl -, mg/l), calcium (Ca 2+ , mg/l), magnesium (Mg 2+ , mg/l), nitrate (NO 3 -, mg/l), nitrite (NO 2 -, mg/l) and sulfates (SO The statistic data analysis showed that a large majority of the results of analyses of almost all the water quality parameters is within predicted limits (Brankovic and Trajkovic 2007). There are numerous examples corroborating this assertion.…”

“…Public awareness, as well as active participation of the public in the decision making process during development and enforcement of legislation are necessary for sustainable water management (Branković, Trajković, 2007).…”

Air pollution as the cause of urban stress. A case study: Nemanjica Boulevard, Nis, Serbia

“…The advantage is that the northeast moderate winds dominate the area thus blocking the higher concentration of exhaust fumes in the air. Nemanjića Boulevard is situated near to Nisava River (Brankovic and Trajkovic 2008), in the eastern part of Niš, in the vicinity of the centre of town and represents a very important traffic route which connects the central to the eastern part of the town. It passes through the town centre parallel with Dr Zorana Đinđića Boulevard and them together flow into Cara Konstantina Boulevard.…”
