Epigraphist H. V. Trivedi identified the Parnna river as the Purna stream that flows beside the Girvad (Girwar) village near Mount Abu and Chandravati. Balogh doubts the accuracy of this identification, noting that this stream is too insignificant to be mentioned as a landmark in the inscription, and is not located on the way from Chadnravati to Malava, where the battle was likely fought. According to Balogh, Parnna may be a shorter form of Parnnasha (IAST: Parṇṇāśā), which is most likely another name for the Banas River.
