I was unsure about submitting it to you because I only know them as two distinct rivers, the rivers are Tarim and Khotan (both in China) however, the Khotan flows into the Tarim so I suppose that a stretch of the river maybe the Tarim - Khotan.
Hello again Purplebird,another thank you,you must have a very good reference book for rivers(better than mine) could you just check AANDRAE for me please.
