Sažetak
Water in forest ecosystem can be present in the forms of precipitation, flood, groundwater and air humidity. Hydrological water cycle takes place via basic hydrological processes such as evapotranspiration, precipitations, infiltration and outflow. Some infrastructural interventions and recent climatic changes in the area of lowland forests have caused changes of flood water and groundwater trends as well as precipitation and evapotranspiration amounts. Water quality is determined by a large number of indicators that can be classified into physical, chemical and biological indicator groups. One of water quality chemical indicators is presence of metals in water. Higher concentrations of metals in natural waters are undesirable as they are polluters of water systems and dangerous for living organisms. Particularly dangerous are cadmium and lead. The objective of this paper is to analyze watercourse levels, groundwater depths, relations between precipitation waters, flood waters, groundwaters and relative air humidity and evapotranspiration. Further objective is to analyze pollution of precipitation and flood waters in lowland forest ecosystems. Research was conducted in the area of Posavina. Precipitation data of Nova Gradiška meteorological station, watercourse levels of Sava River and groundwater depths data from piezometer station were used for analysis of hydrological relations in lowland forest ecosystems. Evapotranspirationwas calculated using Thorntwait method. For water quality analysis, precipitation water was collected at six sampler sites during the spring of 2015. Flood water and lentic water in three microrelief types was collected in three repetitions during the spring of 2015. Water samples were collected in plastic (polypropylene) bottles of 100 ml volume. Trends of river Sava water levels as well as groundwater levels have dropped significantly. Precipitation volume trend in the research area is positive, but not statistically significant, while evapotranspiration amounts have increased significantly. Significant correlation has been determined between particular water forms in hydrological cycle, more precisely, between precipitation waters, flood waters and groundwaters, as well as relative air humidity and evapotranspiration. Pollution of precipitation waters with metals was not found. Flood water was found to be significantly polluted with Al, Fe and Mn in certain microrelief types.
