Sažetak
This paper presents the results of the recession analysis of the karst spring hydrograph for period of 8 years (1994 – 2001). The Bulaž spring is a typical karst well of the rising type. The water appears at the contact of the limestone and Quaternary sediments. The catchment area of the spring (105km2) is built up of highly fractured carbonate rocks (permeable rocks), and flysch sediments (impermeable medium). The recession analysis of karst spring hydrograph was performed manually (Maillet, 1905) and with automated technique (Posavec, 2006). The results were compared and used to predict a minimum spring discharge, to estimat groundwater recharge with adapted method, applied by Meyboom (1961), and to structural adjustment of the karst aquifer system. The results of recession analysis indicate significant and rapid changes of outflow, with fast stabilization on relatively small and steady volume of the baseflow. The calculated recession coefficient refers to a quick drainage, large drainable porosity, large transmissivity and small water storage. In the case of the Bulaž spring, the applied analysis are considered as reliable and highly accurate for practical purposes in water supply.
