The exchange of information and findings obtained in other karst regions worldwide allows for an integral approach to this complex issue, and thereby contribute towards finding reliable solutions. The basic objective of the conference was to apply an interdisciplinary approach to scientifically assess the issues of sustainable development of all forms of karst. The issue was approached from different perspectives, from those of a technical and biological nature, to those addressing the social aspects of environmental issues and life on the karst. The conference itself was held at the Plitvice Lakes (World Heritage Site), one of the most fascinating phenomena on Earth. During the conference, one half-day excursion was organized to visit National Park Plitvice Lakes. Following the conference, an excursion was organised to visit several other significant phenomena of the Dinaric karst in Croatia. Conference themes were: - Geological aspects - Geomorphological aspects - Hydrological and hydrogeological aspects - Coastal and submerged karst - Biological and ecological aspects of karst - Anthropogenic impacts and protecting karst - Sociological, demographic and social aspects of karst - Dinaric karst and other karst regions (China, Alpine, Caribbean karst, etc.) The publication will serve as a contribution to the VIIth Phase of the International Hydrological Programme (IHP 2008-2013) of UNESCO, which has endeavoured to address demands arising from a rapidly changing world.

A sinking surface streamflow can be defined as a surface river or stream flowing onto or over karst and which then disappears completely underground through a swallow hole and which may or may not rise again and flow as a resurgent surface river or stream. A losing streamflow can be defined as an open stream or river that loses water as it flows downstream. The level of water in a losing stream is above the water table: in comparison, the level of water in a gaining stream is below the water table. In a losing stream water infiltrates underground, because the water table is below the bottom of the stream channel. Underground or subterranean streamflows are subsurface karst passages with the main characteristics of open rivers or streams. In underground streamflows water flows through caves, caverns, karst conduits and large galleries in karst underground. The paper treats some conceptual aspects of sinking, losing and underground streamflows. Some cases of the special hydrological and hydrogeological behaviour of karst sinking, losing and underground streamflows are explained. Keywords: karst, sinking, losing, underground streamflow 1 Introduction Karst is defined as a terrain, generally underlain by limestone or dolomite, in which the topography is chiefly formed by the dissolving of rock, and which is characterised by sinkholes, sinking streams, closed depressions, subterranean drainage and caves (Field 2002). A wide range of closed surface depressions, a well-developed underground drainage system, and strong interaction the between circulation of surface water and groundwater typify karst. Due to very high infiltration rates, especially in bare karst, overland and surface flow is rare in comparison with non-karst terrains. Carbonate rocks are more soluble than many other rocks. They are subject to a number of geomorphological processes. The processes involved in the weathering and erosion of carbonate rocks are many and diverse. The varied and often spectacular surface landforms are merely a guide to the presence of unpredictable conduits, fissures and cavities beneath the ground. But at the same time these subsurface
