 However, because of the more arid conditions and equally intensive water use, the discharge of the Aras is much less than the Kura, so downstream of the confluence the river is still called the Kura.About 52% of the river's flow comes from snowmelt and glaciers, 30% comes from groundwater seepage, and roughly 18% from precipitation.Because of high water use, many of the smaller tributaries of the Kura no longer reach the river, instead disappearing in the plain many kilometers from their original mouths.
