Discussion of a recent paper: M. H. Ghobadi; M. Torabi-Kaveh; M. Miri; N. Mahdiabadi; An introduction to the karst geomorphology of the Bisetun–Tāq-e Bostan historical region (northeast Kermanshah, Iran) with special emphasis on karst development as a serious threat for the UNESCO World Heritage Site, Bulletin of Engineering Geology and the Environment, DOI 10.1007/s10064-014-0662-0

The article under discussion, whilst providing generalized accounts of the effects of waterflows in karstic formations, fails, in the opinion of this respondent, to substantiate the claims that an immediate threat is posed to the continued preservation of the monuments at Tāq-e Bostān, the focus of this response.
