Item type:Publication, MEASURING DEPOSED SEDIMENT IN SMALL RESERVOIRS, CASE STUDY: GRADOCE RESERVOIR(Journal Agriculture and Forestry, 2015-06-30)Reservoir sedimentation is a serious consequence of soil erosion with large environmental and economic implications. On the other hand, reservoir sedimentation also provides valuable information on erosion intensity and sediment transport within a drainage basin. A reservoir can be considered as a large scale experiment, as the outlet of a giant erosion plot. With the application of the global navigation satellite system (GNSS), the bathymetric measurements of the sediment in the reservoirs became much easier. The measurements done with GNSS supported echosounder are completed much faster with considerable accuracy. Because the time needed for the measurements is much shorter then besides the measurements of the established profiles also some additional measurements can be done. Namely this new method gives the opportunity for total measurement of the reservoirs on profiles and contour measurement. The case study was done on the reservoir “Gradče” which is a small reservoir with total storage of 1.8 106 m3.The reservoir siltation was measured twice (1984 and 1991) while the latest measurement was done in 2013 with echo-sounder with GPS support. Then the total deposited sediment was calculated and the deposition rates were calculated. It was concluded that until 1984 the deposition rate was 2.5 time higher than the later period (1984-2013).The used measuring method, combination of contour and cross-profile measurement, showed promising results. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Use of modern geomatic techniques for creating and updating a green cadastre of urban trees and shrubs: a case study of Kumanovo city river bank(Ss. Cyril and Methodius University in Skopje, Faculty of Forestry in Skopje, 2018); ; The goal of this paper is to implement modern, up-to-date, geomatics technique and technologies in the environment. The base is made in GIS software, a GPS device is used to record detailed points on the field and for recording and preparing a new orthophoto was used a modern sophisticated drone DJI Mavic Pro. QGIS (Quantum Geographic Information System), as a key software, was used for computer data processing and recordings obtained from the field research, and other utility programs were used to perform the tasks. The subject of the article is the Kumanovo city promenade in Macedonia, which is a convenient place to try and implement this data processing method. The results obtained give us a map of the entire urban dendroflora on the river bank in the city of Kumanovo. In fact, an inventory of all trees and shrubs was carried out, 4 projections were prepared with the help of modern applications, and as the ultimate goal, and a web digital map of the riverbank was prepared. This method can be applied in forestry, agriculture, water management, geodesy, space planning, sustainable development and environmental protection. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Relation between the level of degradation and the wind speed reduction efficiency of tree windbreaks systems in Ovche Pole region, Macedonia(IJERD – International Journal of Environmental and Rural Development, 2022); Mihara, MachitoOvche Pole is an agricultural region in Macedonia with dry climatic conditions characterized by low precipitation and high ambient temperatures during the growing period as well as prevailing winds that are present considerable time of the year. During the 1950s series of measures have been implemented to improve the agriculture productivity in the region. One of the measures taken was the establishment of tree windbreaks (field shelterbelts) aimed to reduce wind velocity and protect shelter crops. Ever since they become essential elements for the regional landscape, performing many important ecosystem functions. As far as authors' knowledge, so far there are no scientific studies that investigated the performance of the tree windbreaks in Ovche Pole-research area of this study. To fill the gap of scientific data, this study examines the relation between wind reduction efficiency of tree windbreaks with their level of degradation in that area. Optical porosity is used as a proxy for quantitative description of the level of degradation of the structure of the tree windbreaks. To this aim, field measurements for wind velocity and optical porosity (OP) were done on 3 (three) windbreaks sections. Photogrammetry method was used to determent the porosity at each windbreak section. Wind velocity field measurements were done with two handheld cone anemometers The windspeed reduction efficiency was assessed by comparing the windspeed at the windward side with the windspeed at 3 points on the leeward side. The results show that the level of degradation is significantly related with the relative windspeed at distance of 30m and 60m from the tree line at the leeward side. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Рачунање R – фактора (фактор ерозивне енергије кише) за потребе моделирања губитака земљишта помоћу RUSLE методе на основу годишњих падавина(Association of graduate engineers in torrent control of Serbia and University of Belgrade, Faculty of Forestry, Belgrade, Kneza Viseslava 1, 11030 Belgrade, 2022); ; Trendafilov, BozhinThe USLE / RUSLE method is the most widely used method in the world for calculating erosion intensity expressed as soil loss. IN the latest period, a map of soil loss EU was made by this method. One of the key parameters for applying the RUSLE method is the R - erosive energy factor for which a global world map model has been created too. In the Republic of North Macedonia there are no available data to use original access for calculation this factor. That is why the approach is based on the annual precipitations. Several equations developed in different parts of the world were analyzed. Calculation was done for data from 17 gauges stations in the country, and at the same time modeling has been done for the whole country on the basis of altitude. Comparison of the obtained values with the results for the border areas and high mountains in Greece and Bulgaria, showed that they are realistic and enable o be further applied in the final modeling for creation of Soil Loss map in the Republic of North Macedonia using RUSLE method. Average R - factor in states amounts to 533 (MJ mm ha-1 h-1 yr-1), and rises from 437 (MJ mm ha-1 h-1 yr-1) in Krivolaka district in the central part of the country, to 835 (MJ mm ha-1 h-1 yr-1) in the southwestern part of Shar Planinа and Korab mountains. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Development of Erosion Protection Zones in the Catchment of the Reservoir “Kalimanci”, North Macedonia(IJERD – International Journal of Environmental and Rural Development, 2023); ; ; Trendafilov, BozhinConstruction of reservoirs is a priority for ensuring sustainability of water resources. In the Republic of North Macedonia, there are 23 big and over 120 small water reservoirs. On the other hand, erosion and the filling of reservoirs with sediment is one of the main problems in reducing the lifespan of the reservoir. The total annual accumulated sediment in all the reservoirs in the Republic of Macedonia is 3,000,000 m3 (Erosion map of RM, 1993). The selected study area for the current research is the Kalimanci reservoir in the frames of the catchment of the Bregalnica River, North Macedonia. The main method used to estimate the sediment transport on catchment level is the Erosion Potential Method (EPM; Gavrilovic method), and the validity is assessed on the basis of accumulated sediment in the reservoirs. The EPM method only estimates the total transported sediment at one point. To estimate how the sediment is transported, re-transported, and accumulated in the river bed, a hydraulic sediment transport model (HEC RAS) was used. Then the critical sub-catchments from an erosion point of view are delineated. Most of the critical sub-catchments are situated around the Kalimanci reservoir, while the middle of the catchment experiences erosion of medium severity, and the highest parts of the Bregalnica River are the least critical. The largest part of the sediment transported by the Bregalnica River (nearly 75%) is deposited in the valleys. With the aggregation of the previous steps, the erosion zones of the Kalimanci reservoir were identified. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The Importance of Urban Planning and Landscape Design in the Process of Creating ‘Great Places’ for Citizens - Case study of Park Macedonia 1(SEEFOR, 2025-08-28); ; ; Orlović, SašaCreating places where urban life is better and of a higher quality is one of the main tasks of the modern society. These places are called ‘great places’ and urban parks have all the predispositions to be one of them. Due to the functions they perform, they are a necessary part of every city. Urban planning and landscape design are very important in the process of creating ‘great places’ for citizens. With their proper use, successful green spaces are created, which are functional and aesthetic at the same time. This is especially important since green areas in the urban environment are becoming less numerous. The subject of analysis in this paper is urban planning and landscape design through the example of Park Macedonia 1 in Skopje, North Macedonia. The park is analysed from different aspects (functionality, safety, plant species selection, layout of the plants and the use of basic principles of landscape design) to determine if this place is a ‘great place’, i.e. whether this place at the same time functional and aesthetic. The results show that Park Macedonia 1 is a ‘great place’; however, there are some gaps in its urban planning and landscape design. These gaps are reflected in the safety of the visitors and the functionality of the park, made in the process of plant species selection and landscape designing of the park, i.e. entrances and exits, layout of plants, incorrect use of focal points, and simplicity, rhythm and line as basic principles of landscape design. Analyses of Park Macedonia 1 in terms of urban planning and landscape design and the proposals for corrections can be used in the future design of ‘great places’ in urban areas like Skopje. - Some of the metrics are blocked by yourconsent settings
