Poljes are very common karst depressions especially in the Dinaric Karst. Despite their many common characteristics, they occur in very different karst environments and function in various ways. Th e research presents a new typification of poljes, which simplifies the previous ones. It defines the poljes according to the geomorphological environment in which they occur as inundated, overflow, inflow and pre-glacial poljes. In the research, we defined all 35 karst poljes in Slovenia on the basis of the new typification.
