What does swollen uvala mean?

A swollen uvala refers to a geological feature characterized by a large, often elongated depression formed by the merging of multiple sinkholes in karst landscapes. This phenomenon typically occurs in limestone regions where dissolution processes have eroded the rock, leading to the formation of these depressions. The term "swollen" suggests that the uvala has expanded or become more pronounced, possibly due to increased erosion or subsidence. Uvalas are significant in understanding karst topography and hydrology.
