Abstract The inflow of mine water to mining operations is often caused by random events such as precipitation. Consequently, the regime can be defined a function applying theory processes. Regression models multiple linear correlation type have been used simulate into operations, produce short-range predictions and facilitate rapid response inside mine. significance lies in ability predict consequences (mine inflow), nature (meteorological parameters: precipitation air temperature)....

The study area is the city of Zintan, in northwestern Libya, which has grown over past 30 years. Its current population roughly 30,000. Although part commercial, most engages agriculture and primarily grows cereal crops (wheat barley). demand growing for agricultural products increased, intensifying use fertilizers, pesticides, insecticides. Consequently, concentrations potentially toxic elements (PTE) soil have increased. To assess quality (to provide a snapshot condition soil), systematic...

Soviet and Mongolian geologists initiated geological exploration of Mongolia for minerals after World War II (1945). These activities lasted until the breakup USSR in 1991. As part this systematic uranium rare element was undertaken across Mongolia. New resumed at beginning 21st century a range ore mineral deposit styles including uranium, coal, base precious metals Fe-ore. This generally by Western-based companies. paper presents results from regional reassessment company 2011 radiometric...

Serbian military topographic and cartographic activity has existed for almost 150 years. During that time, a relatively small country like Serbia faced difficult temptations but successfully produced maps. this period, was affected by numerous wars other trials. First, there war liberation with the Turkish Empire, then came Balkan Wars, First Second World Wars transformation of Yugoslavia from kingdom into socialist state, as well final disintegration Yugoslavia. all army managed to create...

Groundwater is a renewable resource wholly or partially protected from external influences (pollutants) by nature. Currently, about 75% of the population Republic Serbia meets its water needs using underground water. Hence, this represents an essential strategic our country; according to data Water Management Foundation (VOS, 2001), existing sources used in quantities 23m3/s. As 67.13m3/s estimated potential Serbia, we state that only 1/3 total available these waters usage. Therefore, can...

Monitoring of water levels and flow rates the Velika Morava River, due to its significance for Republic Serbia, was established over 100 years ago at profiles Ljubičevski Most Ćuprija. This followed a year later by activation Varvarin monitoring station, then in 1935 Žabarski Most, 1952 Bagrdan station. Groundwater started 1977 with 12 piezometers network gradually expanded include 92 2002. study presents comparative analysis level elevations River associated arranged along normal river...

According to the tectonic architecture of Balkan Peninsula, territory Macedonia belongs Dinarides, Rhodope and Carpatho-Balkanides. In a relatively small area, has very complex geological structure, which was shaped by intense long-term processes, followed magmatism wide spectrum, from ultrabasic acidic. From stratigraphic point view, formations consist oldest Precambrian high-grade metamorphic rocks youngest Quaternary deposits, such structure conditions creation different hydrogeological...

The Loess plateau is a geological formation that originated during the Pleistocene epoch and prevalent in Vojvodina, Serbia. type of sedimentary rock made up fine siltstones; it exhibits subtle layering, capillary porosity, vertical collapsing. This was created through silt-sized fraction deposition dust carried by wind over grassy regions colder periods. Over time, these deposits were lithified, layer paleosol developed above loess warmer climate phases. Up to Slankamen area, maintains...

The monitoring and analysis of concentrations toxic metals (lead cadmium) in soils crops indicate that farmland Serbia is generally not polluted, the quality naturally good. Such are therefore suitable for organic farming. All noted instances contamination by a local nature only, result fertilizers pesticides, municipal waste, exhaust gases, nearby production facilities, smelting plants, mines, tailings ponds, etc. Locations this type need to be monitored regularly, status soil assessed....

The Velika Morava River originates at the junction of Južna and Zapadna town Stalać in Serbia. It is 185 km long empties into Danube. Basin occupies a land area 37 444 km2. river flows through central Serbia, which features most fertile highest population density country. Public water supply this region Serbia relies on groundwater formed alluvial sediments Morava. Both industry agriculture are well developed. There intensive sand gravel mining along riverbanks, has deepened channel by as...

The aim of the study was to evaluate potential risks radiation near abandoned uranium mines, tailing dumps, or deposits on Mountain Stara Planina, Serbia. For risk assessment several parameters were determined: radium equivalent activity, Raeq, external hazard index, Hex, gamma absorbed dose rate, D, annual effective background outdoor exposure, AEDoutdoor, and excess lifetime cancer risk, ELCR. Obtained results showed that all samples, except one, have Raeq value up two times higher than...

Dojkinacka River is one of the rare small river basins in Republic Serbia where regular measurements water levels and flows are made. Hydrometeorology Department has been carrying out flow regime since 1981, using measurement station Visocka Rzana which 205m upstream from river's flowing into Visocica. These still applied today therefore there data for last 35 years classifies this basin as hydrologically researched followed-up basin. However, problem that they usually not well covered by...

Detailed hydrological and hydrogeological assessments of karst spring discharge require information about the groundwater regime in study area/watershed. However, monitoring is often organized locally sporadically, as required for specific studies or projects, seldom lasts longer than one year. On other hand, if time series quantitative parameters are shorter 15 years, watershed considered to be ungauged. As a result, aquifer budget ungauged watersheds can misleading. To minimize water...
