Abstract

The area with which we are concerned extends from the southern border of the Sudan to Kosti on the White Nile, from latitude 3° 30' N. to latitude 13° N. The tribal areas in which the effects of the Equatorial Nile Project will be felt directly are those on the banks of the main rivers, the Bahr el Jebel, the Bahr el Zeraf, the White Nile, and parts of the Bahr el Ghazal and the Sobat. They lie roughly between longitudes 29° and 34° East. The description of this area from the point of view of hydrology will have to include oth~r areas whose rivers run into and affect the Jonglei Area itself. For convenience, the topographical account which follows is divided into four parts, the first dealing with the main rivers, and the remainder with each of three natural hydrological divisions which are as fonows: (I) East of the Bah"l"el Jebel and south of the White Nile and the Sobat-the South-Eastern Area. (2) West of the BahT el Jebel and south of the BahT el Ghazal- the South-Western Area. (3) North of the White Nile to Kosti-the Northern Area.
