Hittite records indicate that Samuha was located on a navigable river, which tends to support the Euphrates location. Oliver Gurney notes in the above-cited work that the Halys river is also navigable in sections. He favored the Euphrates location, noting that the Murad Su, the present day Murat River had river traffic in 1866. The Murat river is a tributary of the Euphrates river. Both proposed locations are south of the Kaskian incursion that overtook Hattusa and required the Hittite leadership to move to Samuha.
