– A Swallow Hole (Ponor) is a point where surface water disappears underground, typically small in size.
– A Sink Hole (Doline) is a closed depression in the ground surface caused by dissolution or collapse, larger than a swallow hole but generally smaller than uvalas and poljes.
– An Uvala is a compound sinkhole formed by the merging of several dolines, thus larger than a single sinkhole.
– A Polje is a large, flat-floored depression in a karst region, often elongated and bounded by steep walls. They can be several kilometers long and wide and are the largest karst depressions.
