which river takes its name from loess soil
Yellow River Early Chinese literature including the Yu Gong or Tribute of Yu dating to the Warring States period (475–221 BC) refers to the Yellow River as simply 河 (Old Chinese: *C.gˤaj,[2] modern Chinese (Pinyin) Hé), a character that has come to mean "river" in modern usage. The first appearance of the name 黃河 (Old Chinese: *N-kʷˤaŋ C.gˤaj; Middle Chinese: Huang Ha[2]) is in the Book of Han written during the Eastern Han dynasty about the Western Han dynasty. The adjective "yellow" describes the perennial color of the muddy water in the lower course of the river, which arises from soil (loess) being carried downstream.
Arkansas River At 1,469 miles (2,364 km), it is the sixth-longest river in the United States,[7] the second-longest tributary in the Mississippi–Missouri system, and the 45th longest river in the world. Its origin is in the Rocky Mountains in Lake County, Colorado, near Leadville. In 1859, placer gold discovered in the Leadville area brought thousands seeking to strike it rich, but the easily recovered placer gold was quickly exhausted.[8] The Arkansas River's mouth is at Napoleon, Arkansas, and its drainage basin covers nearly 170,000 sq mi (440,300 km²).[5] In terms of volume, the river is much smaller than the Missouri and Ohio Rivers, with a mean discharge of roughly 41,000 cubic feet per second (1,200 m3/s).
