River Gipping
The River Gipping is the source river for the River Orwell in the county of Suffolk in East Anglia, England, which is named from the village of Gipping, and which gave its name to the former Gipping Rural District. The name is unrelated to the name of Ipswich. It rises near Mendlesham Green and flows in a south-westerly direction to reach Stowmarket. From there it flows towards the south or south east, passing through Needham Market and a number of villages to reach Ipswich, where it becomes the Orwell. The river has supplied power to a number of watermills, several of which are still standing. None are operational, although the mill at Baylham retains most of its machinery, and is the only complete mill on the river.
Gibe River
The Gibe rises at an elevation of more than 2,000 m north of Bila town and west of the Chomen swamp (specifically, from Gudeya Bila woreda, which is located in the East Welega Zone, Oromia Region). The river is then flowing generally to the southeast to its confluence with the Wabe River. Its tributaries include the Amara, Alanga and Gilgel Gibe rivers. The southern drainage area of the Gibe includes the historic Gibe region, where a number of the former kingdoms of the Oromo and Sidama peoples were located. The Gibe River terminates at the confluence with the Wabe River at an elevation of 1060 m from where the resulting river downstream is called the Omo River.
