Abstract

The paper deals with complex hydrological/hydrogeological behaviour in the Rjecina karst spring and river basin located in the north-western part of the deep and developed Croatian Dinaric karst. The Rjecina Spring is one of the major karst springs in Croatia, used for water supply of Rijeka City and its surrounding area. Beside the use of Rjecina spring for water supply, the development of the Rijeka hydroelectric power plant (HEPP) also changed hydrological and hydrogeological regime of the whole catchment. In order to analyse the anthropogenic influences in the system, hydrological analysis of the Rjecina river and spring discharge was done, as well as the analysis of the available data of groundwater measurements. The analysis showed that, due to the increase of water caption and decrease of precipitation, the average annual spring discharge decreased for approximately 25% in the 1980-2016 period. Detailed analysis of groundwater measurements indicated aquifer behaviour and the need for additional measurements and catchment delineation. Key words: hydrology, hydrogeology, karst, Rjecina Spring, Rjecina River, Dinaric karst.

Rječina岩溶泉水和河流（Dinaric岩溶）的水资源分析

本文研究了位于克罗地亚迪纳里克岩溶深发育区西北部的Rjecina岩溶泉和河流域复杂的水文地质行为。Rjecina泉是克罗地亚主要的喀斯特泉之一，用于里耶卡市及其周边地区的供水。除了使用Rjecina泉供水外，Rijeka水电站(HEPP)的开发也改变了整个流域的水文和水文地质状况。为了分析该系统的人为影响，对Rjecina河和泉水流量进行了水文分析，并对现有地下水测量数据进行了分析。分析表明，1980—2016年，由于水量增加和降水减少，年平均春季流量减少了约25%。对地下水测量的详细分析表明，含水层的行为和需要进行额外的测量和集水区划定。关键词:水文学，水文地质，喀斯特，Rjecina泉，Rjecina河，Dinaric喀斯特中文名称:aniziza vodnih virov kraskega krasa (Dinarski kras); cliek obravnava zapletene hidroloske/hidrogeoloske razmere v zaledju kraskega in reke Riecine v severozahodnem delu globokega in dobro razvitega hrvaskega Dinarskega krasa。Izvir Rjecina je eden najvecjih kraskih izvirov na Hrvaskem, zajet je za oskrbo ' s pitno vodo za mesto Reka in njeno okolico。Poleg rabe izvira Rjecine za oskrbo z vodo je razlog za spremenjen hidroloski in hydrogeology režim celotnega zaledja tudi gradja hidroelektrarne Reka (HEPP)。分析人类的生长发育和生长发育系统，分析人类的生长发育和生长发育，分析人类的生长发育和生长发育，分析人类的生长发育。1980-2016 zmanjsal za približno 25%。虎翅虫分析有价值的动物，有价值的动物，有价值的动物，有价值的动物，有价值的动物，有价值的动物。kljune: hydrorologija, hydrogeoologija, kras, izvir Rjecina, reka Rjecina, Dinarski kras。

期刊介绍： Karst areas occupy 10-20 % of ice-free land. Dissolution of rock by natural waters has given rise to specific landscape and underground. Karst surface features and caves have attracted man''s curiosity since the dawn of humanity and have been a focus to scientific studies since more than half of millennia. Acta Carsologica publishes original research papers and reviews, letters, essays and reports covering topics related to specific of karst areas. These comprise, but are not limited to karst geology, hydrology, and geomorphology, speleology, hydrogeology, biospeleology and history of karst science.
