Rajesh Kocchar further notes that, even if the Sutlej and the Yamuna had drained into the Ghaggar during Rigvedic, it still would not fit the Rigvedic descriptions because "the snow-fed Satluj and Yamuna would strengthen lower Ghaggar. Upper Ghaggar would still be as puny as it is today." Helmand river An alternative suggestion for the identity of the early Rigvedic Sarasvati River is the Helmand River and its tributary Arghandab in the Arachosia region in Afghanistan, separated from the watershed of the Indus by the Sanglakh Range. The Helmand historically besides Avestan Haetumant bore the name Haraxvaiti, which is the Avestan form cognate to Sanskrit Sarasvati. The Avesta extols the Helmand in similar terms to those used in the Rigveda with respect to the Sarasvati: "The bountiful, glorious Haetumant swelling its white waves rolling down its copious flood". However unlike the Rigvedic Sarasvati, Helmand river never attained the status of a deity despite the praises in the Avesta. The identification of the Sarasvati river with the Helmand river was first proposed by Thomas (1886), followed by Alfred Hillebrandt a couple of years thereafter. According to Konrad Klaus (1989), the geographic situation of the Sarasvati and the Helmand rivers are similar. Both flow into terminal lakes: The Helmand flows into a swamp on the Iranian plateau (the extended wetland and lake system of Hamun-i-Helmand). This matches the Rigvedic description of the Sarasvati flowing to the samudra, which according to him at that time meant 'confluence', 'lake', 'heavenly lake', 'ocean'; the current meaning of 'terrestrial ocean' was not even felt in the Pali Canon. Rajesh Kocchar, after a detailed analysis of the Vedic texts and geological environments of the rivers, concludes that there are two Sarasvati rivers mentioned in the Rigveda. The early Rigvedic Sarasvati, which he calls Naditama Sarasvati, is described in suktas 2.41, 7.36, etc. of the family books of the Rigveda, and drains into a samudra. The description of the Naditama Sarasvati in the Rigveda matches the physical features of the Helmand River in Afghanistan, more precisely its tributary the Harut River, whose older name was Haraxvatī in Avestan. The later Rigvedic Sarasvati, which he calls Vinasana Sarasvati, is described in the Rigvedic Nadistuti sukta (10.75), which was composed centuries later, after an eastward migration of the bearers of the Rigvedic culture to the western Gangetic plain some 600 km to the east. The Sarasvati by this time had
