Identification of Depth in South-Western Bosnia Using the Tracer Method

Abstract

The Glamocko Polje is the surface and underground watershed between the river basins of the Black Sea and the Adriatic Sea. The recharge areas of groundwater, flow towards the Bistrica, Zabljak, and Duman springs (in the Livanjsko Polje and River Cetina basins) towards the south; to the Ribnik and Sana river springs towards the north, and to the Pliva and Janja river springs. Complicated thrust tectonics, hanging and deep-lying hydrogeological barriers give rise to complicated hydrogeological relations. Groundwater tracing helped to determine the position of watersheds and depths to groundwater in this part of the Dinaridic karst. Water discharge at the named springs is controlled (besides the temporary flooding of the poljes), by groundwater karst conduits from the swallow holes to the springs.
