The Changane River (Rio Changane) is a river in Mozambique, a tributary to the Limpopo River which it joins near the coast, just past the town of Chibuto. It forms part of the eastern boundary of Gaza Province. The Changane is the easternmost tributary of the Limpopo, entering it from the left near its mouth on the Indian Ocean
The Changane and its main tributaries rise close to the border with Zimbabwe.
The river runs southwards roughly along the 34°E line of longitude from about 22°S to about 24°S latitude.
The river drains the wetlands of Banhine National Park.
The basin covers 6,557,055 hectares (25,316.93sqmi), or about 15.9% of the Limpopo Basin.
The river mainly flows through a dry region.
In the interior, annual rainfall is as low as 400 millimetres (16in), rising to 800 millimetres (31in) near the coast.
The Changane River Valley is near sea level, and was once a beach line.
The Changane has a very low runoff coefficient and long periods with no discharge at all.
... risks of flooding in and around Beira, Buzi and Nhamatanda, “severe river flooding is probable in the Lower Limpopo basin” where the Changane tributary joins the Limpopo near Chibuto, with the Chokwe and Xai-Xai districts in Gaza Province expected to be hardest-hit.
