Sažetak
A conceptual approach and the resulting mathematical model for groundwater budget estimation are presented. The karst underground is considered as a lumped system that contains the soil cover, epikarst, phreatic and vadose zones, where the epikarst is divided to the perched and transitory zones. The proposed parameter estimation procedure merges the soilmoisture- balance and the groundwater-balance approaches in order to obtain the complete groundwater budget. The effective rainfall is calculated by using the mathematical model based on soil-moisture balance equations. This model considers separately the soil cover and epikarst perched storage. The groundwater recharge is calculated by applying the mathematical model based on groundwater balance equations. The groundwater recharge model consists of two linear and one nonlinear reservoir representing the vadose seepage, vadose flow and shaft flow. The proposed model is applied to the Jadro Springs located in the Dinaric karst area in Croatia.
