Proglacial karst system: example from Blidinje, Bosnia and Herzegovina

Blidinje is tectonically derived lowland in the Dinaric Alps within Bosnia and Herzegovina. It is engulfed between the Vran, Čvrsnica and Čabulja Mountains. The Blidinje study area is predominantly built of limestone and dolostone, where karst, fluvial and glacial geomorphological systems interchange. The area was occupied by piedmont type glaciers as can be recognised from the palaeoglacial landform morphology, which exhibit large lobate moraine ridges or hummocky moraines on a predominantly levelled surface. The exceptionally well-preserved moraines indicate that the largest piedmont glacier lobe was ̴3 km wide and more than 100 m thick. Piedmont glaciers in Blidinje formed due to unconfined plain, adjacent to the mountain. Some slopes above the Blidinje depression acts as a fluviokarst, which is indicated by fluvial erosion on steep slopes and local deposition beneath them. Due to complex nature of the study it is acting as a depositional trap for interchanging depositional sequences of the surrounding non-karstic interferences.
