The Phum Duang River (or Khiri Rat River), which drains another 6,125 square kilometres (2,365 sq mi) west of the Tapi watershed, joins the estuary 15 kilometres (9 mi) west of Surat Thani in Phunphin district.

The river was named on 29 July 1915, after the river Tapi in Surat, India, shortly after the town of Surat Thani was named after the town Surat in Gujarat, India.

The island of Ko Lamphu (เกาะลำพู) is in the Tapi River, about 9 kilometres (6 mi) from its mouth, near Surat Thani town center.[1]

In 1975, an area of 29.6 square kilometres (11.4 sq mi) of swamp land on the east bank of the river in the Khian Sa District was declared the Nong Thung Thong non-hunting area.
