GIS MODELLING OF SOLAR POTENTIAL IN TOPLICA REGION

by Aleksandar Valjarević

In this paper we investigated possible potential solar area on Toplica region based on GIS (Geographical Information system) and using a special kriging method with the help of open sources GIS software Quantum GIS. This kriging method is very special to vectorized and calculated the small area. The statistical approach calculated between datasets of three meteorological stations (Niš, Prokuplje, Kuršumlija). Data using of insolation from that meteorological stations from the period of (1953-2013) is useful for a solution to calculating solar potential. The also used parameter is hypsometry of relief of the whole area of Toplica region. Area of Toplica region is 2.231 km2 with a population of 90600 citizens. Divided into fourth municipalities (Prokuplje, Žitoradja, Black, Kuršumlija). The GIS modeling indicates that ideal areas for solar development are located the potential places in Toplica region. Only 13.6 km2 of the head model scores that were in the 90-100% range. However, given the statewide high insolation values with minimal variance, solar projects may be better suited for small-scale residential or commercial projects.

CLIMATIC REGIONS OF KOSOVO AND METOHIJA

by Radomir Ivanović, Aleksandar Valjarević, Danijela Vukojičić, Dragan Radovanović

The Following the average and extreme values of climatic elements, specific climatic indices and field research, we can select three climatic types in Kosovo and Metohija - the altered Mediterranean, continental and mountainous type. The altered Mediterranean type is present in southern and western Metohija , to be specific, it affects the Prizren Field, the Suva Reka and Orahovac Valley as well as the right bank of the Beli Drim from Pecka Bistrica to the Serbia - Albania border. Gradually and practically unnoticeably, it transforms itself into a moderate continental type which dominates over the remaining valley and mountainous parts of Kosovo. It affects parts of northern Metohija, Drenica and the entire Kosovo valley along with smaller sidelong dells - Malo Kosovo and Kosovsko Pomoravlje. Because of their exquisite heights, the mountains that complete the Kosovo Metohija Valley have a specific climatic type, at their lower slopes it is sub - mountainous and at the higher ones it is typically mountainous. Within these climatic types, several climatic sub regions are present. Their frontiers are not precise or sharp. Rather, their climatic changes are gradual and moderate from one sub-region to the other.

MONITORING OF THE ABSORBED DOSE OF RATES RADIATION IN THE RURAL AREAS

by Biljana Vučković, Smilja Čanaćević

Man is constantly exposed to radiation from the radionuclides from the environment. This study presents the results of measuring the absorbed dose rates of natural ionizing radiation in rural areas in the municipality of Štrpce, in southern part of Kosovo and Metohija. The measurements were conducted in 20 houses in two cycles: when rooms were not heated, and when they were warmed up in the same season. Ten observed houses were with basement rooms, and ten others were without basements. The absorbed dose rate of radiation was measured by Gaiger-Miller's counter DR-M3. Mean value of the measured absorbed dose rate was 1.93 μGy/h - in the first cycle and 1.47 μGy/h - in the second cycle. At the same time the values of the absorbed dose of radiation in the environmental were measured, and obtained values were 1.77 μGy/h and 1.33 μGy/h, respectively. Relations between absorbed dose in the premises and in the environment were 1.09 in first cycle, and 1.1 in the second cycle of measurements.
