The objective of this work is the study of two adjacent karst springs Jadro and Žrnovnica in Croatia. This work focuses on the effects of temperature, relative humidity, rainfall and discharges on the behaviour and relations of two adjacent karst springs. Partial correlation analysis implies that the impact of the control signal on the cross-correlation function between the input and output signal can be detected from the correlation coefficient between the input signal and control signal and from the cross-correlation function between the control signal and output signal. The groundwater recharge depends on the process of evapotranspiration and rainfall, so air temperature, relative humidity and rainfall control the spatial and temporal distribution of this process. The major contribution of the paper relies on the utilization of simple correlation and fist-order partial correlation analysis to characterize the functioning and relations of two adjacent karst springs in a dry and wet hydrological year by using hourly data. It has been confirmed that in the case of adjacent karst springs the discharge of each spring has effect on the rainfall-discharge correlation of the other spring. The demonstrated approach represents an improvement in investigating the relations of adjacent karst springs in dry and wet periods, and can be applied on any adjacent karst springs.
