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.
Gaoping River
The Gaoping River headwaters originate near Yushan in northern Kaohsiung’s Tauyuan District and a small part of southern Nantou County. The upper section of the river, known as the Laonong, flows through a series of rugged canyons, through Liouguei and Gaoshu, and is joined by the Zhuokou River. The Laonong emerges from the mountains at Meinong as a wide braided stream and after being joined by the Ailiao from the east, the Gaoping proper is formed, which flows about south along the coastal plain, through Pingtung County, emptying into the Taiwan Strait in Linyuan District. The Qishan River and the Wuluo River flow into the lower section of the Gaoping from north and east, respectively.
With an average annual discharge of , the Gaoping River is the second largest of Taiwan’s rivers by volume, following the Tamsui River. About 90 percent of the precipitation, and consequently about 70–90 percent of the total flow, occurs during the rainy season from May to October. Like many Taiwanese rivers, the Gaoping carries large amounts of silt, ranging from 36 to 49 million tons per year; it is the second largest river in Taiwan (after the Zhuoshui River) in terms of suspended-sediment load.
