Evaluation of simple reference evapotranspiration (ETo) methods has received considerable attention in developing countries where the weather data needed to estimate ETo by the Penman–Monteith FAO 56 (PMF-56) model are often incomplete and/or not available. In this study, eight pan evaporation-based, seven temperature-based, four radiation-based and ten(More)

Topic of this paper is air pollution as a cause of urban stress. This problem is analyzed within a case study in Bulevar Nemanjića in Niš. For the observed location, the measurements were conducted in a period of eight months (May 2007 – June 2007) by the Health Protection Institute in Nis. Motor traffic exhaust gases which were observed were:(More)
This paper presents the results of a study that simulates historic average discharges by means of an Artificial Neural Network, within a variety of input data combinations. A cluster of small area watersheds in Eastern Serbia was selected for the study. The input data considered were: climatic data (precipitation, average air temperatures, vapor pressure(More)
