AB  - The complex Krupaja karst system, located in Serbia, which consists of a strong karst spring, a thermal karst spring, and a borehole that captures sub-thermal waters, has been studied. A phenomenon which gives rise to the occurrence of karst waters of three different temperatures within a relatively short distance (about 200 m) led us to assume that these karst waters are formed within the same karst aquifer and circulate through different levels of karst channels that are zonally distributed within a vertical profile; this was confirmed by assessing the groundwater ages. Based on the development of karstification, as presented in this paper, as well as on previous investigations, explanations of four types of circulation within same karst system are provided. The results of measurements of stable isotopes (H, 18O, and 13C) and radioactive isotopes of tritium and T+He and 14C, as well as hydrochemical water analyses, speleogenetic spatial modeling, speleodiving research, etc., confirmed the assumption that these groundwaters belong to the same karst system. However, these karst waters have different residence times, i.e., from only a few days to over several decades and even up to approximately 4000 years, circulating through channels with various distributions along the depth of the karst aquifer.

AB  - The results of long-term groundwater monitoring in the Bileća reservoir adjacent (eastern Herzegovina, Bosnia and Herzegovina) indicate that there is a good hydraulic connection between the reservoir and the karst aquifer located in the right bank of the reservoir. In remote parts of the right-bank karst aquifer, due to complex lithostratigraphic characteristics and a tectonic structure, the influence of the reservoir is very variable and has been insufficiently studied up until now. This paper presents the analysis and synthesis of new, relevant hydrogeological data, as a basis for the creation of a 3D spatial model, i.e., the analysis of the karst system’s behaviour, both under regular and artificial hydrological conditions of surface reservoir construction and its continuous use (filling and emptying). The interactive connection of the model and complex surface and groundwater time series monitoring data of this system is presented through the analysis of its hydrodynamic characteristics, which completes the spatial model of the karst regime caused by low and high groundwater levels and low and high reservoir water levels. The integration of all the data into one model and further multiparametric analyses revealed the different types of hydrodynamic conditions prevailing in the karst aquifer with regard to the influence of the high or low waters of the reservoir.

AB  - Eastern Herzegovina is highly karstified area, with porosity of karstified rock mass between 0.8 and 2%. It is an area with high precipitation (average annual values in wet year are around 2450 mm), but its distribution is uneven, with 70% of annual precipitation occurring during the wet season (late fall to early spring). The outflow coefficients are very high, between 0.7 and 0.8. The ratio between flow in the low water period (Q95%) and in the period of high water flow (Q1%) is 1:4000(5000). Due to such hydrological conditions, with limited dewatering capacity of karst channels and ponors, floods of karst poljes occur frequently. This article presents, in very general terms, the properties of the natural water regime of the Gatačko Polje, highest polje in Eastern Herzegovina, including some hydrological and hydrogeological specificity. Special attention is referred to floods and possible ways to mitigate such events, as there are coal mine and coal power plant “Gacko” situated in the polje. Several possible measures are presented in the paper, such as passive protection measures, active flood protection by proper reservoirs management, as well as spatial planning measures. Also, the possibility of transferring part of the water from the Gatačko Polje watershed to the multipurpose hydrosystem Trebišnjica for usage in hydropower production, irrigation, water supply and other secondary benefits is considered.

AB  - In general, karst is known as extreme environment for construction of large structures. The average precipitation of karst poljes at Dinaric region of the Eastern Herzegovina for a wet year is about 2450 mm. Daily precipitation can be more than 250 mm. Due to prevailing underground drainage and limited dewatering capacity of ponors the floods are frequent. Only agricultural land is in the karst poljes, which remain flooded from 150 to 250 days in average per year. The population remains low as these difficult living conditions have driven people out of this region for many decades. Possibilities for socio-economic developments are poor. One of these poljes the Gatačko Polje is situated at the highest elevation of the Eastern Herzegovina. Uneven water regime of polje is typical for regions with deep and high developed karst. Sometimes floods are disastrous particularly for infrastructure. To change inconvenient natural water regime a few possible options are analyzed.
In article are presented, in very general, properties of natural regime of the Gatačko Polje, including some hydrological and hydrogeological specificities. Many decades behind two mutually coupled questions were analyzed: possibility to transfer the part water from the Gatačko Polje catchment to be used at the Multipurpose Hydrosystem Trebišnjica for power production, irrigation, water supply and other secondary benefits, and at the same time, to protect infrastructure, particularly to prevent disastrous effect on the Thermal Power Plant.
