The Planina Polje is located in the northwestern part of Notranjsko Podolje, Slovenia. Annual floods cover the flattened floor of the polje at elevation 445 m a.s.l. and reach the depth of approximately 8 meters. Loamy sediments which were found on surface and subsurface features from the inflow part of Planina Polje up to the elevations of about 495 m a.s.l., indirectly show that floods in the past must have been much more extensive than the recent ones. Radiocarbon dating of flowstone layer from such extreme floods appeared around 5,706 t +- 49 BP. The time frame of the flood roughly corresponds with the Altihermal (8,000-5,000 BP). More humid mid-Holocene climate might be the main cause for the high floods on Planina Polje.
