“…Obviously, it is achieved with wisely water management. BONACCI et al [2012] applied linear programming method to get optimal water distribution for the Korčula. They took even the agriculture into account, but they did not elaborate actual agricultural requirements.…”

The island of Korčula is located along the eastern coast of the Adriatic Sea. It has Mediterranean climate with mild and wet winters and hot and dry summers. The island's water supply has been managed in two ways: through a pipeline from the mainland and by drawing groundwater. The island's water is mainly used for drinking and for sanitary needs of the population and tourists, and only a small part is used in industrial production. Tourism causes high seasonal water needs which can hardly be met with the existing water supply system. Agriculture has long tradition on the island. Today, 3 500 ha are cultivated which is about 12.7% of island area, while only 20 ha are irrigated. Therefore total agricultural production is variable and mainly depends on climate. Due to more often and stronger droughts, yields are decreased which causes high economical losses. This paper deals with island's natural features, water needs especially for agriculture, water resources management and finally it suggests measures and activities to improve existing water use.

“…Spectral and correlation analyses are common and generally accepted methods of hydrological research in karst areas [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. However, standard hydrological research of the Dinaric karst in Croatia has been carried out mostly on smaller areas and some regional research [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40], while spectral and correlation analysis began to be carried out recently in the southern parts of the Dinaric karst [41][42][43][44][45].…”

Correlation and cross-spectral analysis of hydrographs was performed on the karst area of the mountainous section of the Kupa River in two time periods. Since there are karst aquifers in this area that is a part of strategic groundwater reserves of potable water, such an analysis could give better insight into the behavior of these aquifers. The functions used to describe karst aquifers are the cross-correlation function, coherence function, gain function, and phase function. The outcomes of the analysis results were very similar in the two analyzed periods, suggesting that differences in input signals between these two periods do not affect the aquifer function as a system filter. The results of this research suggest that the aquifer and overburden layer characteristics have a much stronger influence than the change of input signal on the runoff regime in the considered period.

“…Physical and chemical processes, including tectonic movements in limestone, dolomite, and other soluble rocks, have formed well-linked fissure systems in karst massifs, with dimensions varying from micrometers to several meters [3]. Water rapidly infiltrates the underground network of karst channels because there is extensive development of dissolution pores, caverns, solutional cavities, and subterranean stream systems, which causes surface-water scarcity [1,[4][5][6][7][8].…”

A groundwater model is needed to describe the complex groundwater confluence process of the groundwater system in karst areas. This is because surface water flows through dolines, grikes, and by other means and is directly exchanged with the groundwater. In this study, using the Xin’anjiang model, the conversion of surface water into groundwater and the influence of multiple series-parallel underground reservoirs on groundwater confluence through the generalization of dolines in karst areas were simulated. The water cycle process in the Sancha River Basin was simulated with measured data using multiobjective particle swarm optimization. Then, model parameters were validated with measured runoff data and compared with simulation results obtained using the traditional Xin’anjiang model based on its optimal parameters. The results showed that the determination coefficients of all hydrological stations over the study period were >0.76, and the Nash efficiency coefficient was >0.76, which were better than those for the improved Xin’anjiang model. Next, the simulation accuracy of the flood period in the karst area was analyzed. The model achieved a high fitting rate for the main flood peaks in a year, and the passing rate for the worst hydrological stations was 53%. Finally, the influence of karst development on the runoff was examined. The results indicate that different karst development stages and the heterogeneity of the karst in the basin have different effects on runoff.
