Summary: Identification and modelling of karst hydrological system is based on analysis of flow in karst according to ground water levels and karst spring hydrographs fluctuation. By analysing the hydrographs of karst springs it is possible to identify aquifer characteristics and, accordingly, the main features of a karst rock - fissure massif. Consequently, relevant data can be obtained by analysing hydrograph recession curves. The project presents a detailed analysis and exploration of numerous cases of break points on recession curves via various values of the recesion coefficient alfa in Maillet's equation. It also identifies the relationship between alfa and a linear reservoir coefficient by employing groundwater hydrograph method. It is shown that the linear reservoir coefficient changes with time in accordance with changes of the flow conditions in the karst massif. The main goal of scientific investigations deals with various methods of solving the complex problems of the hydrological transformation of rainfall into runoff in karst terrains. A lot of examples of a typical karst catchment are used to illustrate, explaine and solve several hydrological problems in karst. According numerous intensive investigations it is possible to define catchment area in karst and the volume of the underground karst reservoir.

Keywords: Karst hydrology, Karst spring hydrograph, Recession curves and recession coefficient alfa, Ground water in karst, Rythmic karst springs, Water tracing in karst, Karst aquifer, Catchment area and boundaries in karst.

Research goals: IDENTIFICATION AND MODELLING OF KARST HYDROLOGICAL SYSTEM
