Introduction to the Purari River catchment ( Papua New Guinea).

Abstract

The Purari catchment occupies a considerable portion of the central and southern part of mainland Papua New Guinea. It lies between the Kikori and Vailala rivers, and its headwaters comprise the basins of the Erave, Kaugel, Wahgi, Asaro and Aure rivers. The main divide between the north and south flowing rivers of the New Guinea island runs along the Hagen Range, the Sepik-Wahgi Divide, and the Bismarck Range. These three mountain ranges form part of the watershed of the Purari catchment. -from Author
