Sažetak
Local water resources on karst islands are of high importance due to their specific location and general characteristics of karst. They are characterized by spatial detachment and isolation from the regional aquifer, as well as greater openness to the influence of the sea and salt intrusions, especially in terms of continuing and intensifying the present trend of sea level rise. Beside the use of well known hydrologic and hydrogeological methods in the research of water resources increase and their exploatation, such detachment and isolation dictates application of some new, innovative approaches. This paper shows an analysis of the island of Krk that is located in northern Adriatic with the area of 405.2 km2.and approximately 18, 000 permanent residents. Number of inhabitants increases drastically during summer months due to numerous visitors, when the island's water reserves are minimal. The paper describes methods for estimating global water balance of the island using Langbein's method in GIS environment, detection of coastal concentrated groundwater discharges using thermal- infrared images, and the use of the results of the performed analysis for the island's aquifer functioning on specific water intake locations. The most important water resources of the Krk Island are: coastal lake Njivice (cryptodepression) and accumulation Ponikve in the central part of the island. For these two permanent surface water phenomenon correlation analysis of the dynamics of the surface water and groundwater fluctuations will be performed. The paper also describes evaluation of the possibilities of using precipitation to meet part of the island's water needs in agriculture.
