Water management in karst areas is a challenge as the regime of waters is generally characterized by substantial temporal variability. Water balance analysis is a necessary part of hydrogeological research. The aim of the paper is to study specific features of the water regime and balance of karst springs from the Lovech-Tarnovo karst basin, as well as to evaluate their recharge area. For monthly water balance calculations, the software WaterbalANce was used that is based on the Thornthwaite–Mather method. In addi...

Many studies confirm a shift to warmer climate in South East Europe. In Bulgaria, warming trends have been registered since the end of the last century, and different scenarios show increased air temperatures in the future. In the face of climate change, it is a challenge to assess its effect on water resources. The aim of the paper is to evaluate the possible impact of climate change on the discharge of two springs from the Lovech-Tarnovo karst basin. This study uses the monthly water balance method to compare th...
