Changhua Plain
Changhua Plain, which is sometimes listed as "Changhua Coastal Plain", is an alluvial plain in central Taiwan on the west coast between the Old Zhuoshui River and Dadu River, and bordered to the east by the Bagua Plateau.
It occupied the northern parts of Changhua County, with a length of about 40 km and a width varying between 12–15 km. While the area is mostly flat, the altitude ranges from about 12 m to 45 meters above sea level.
Except for Bagua Plateau, Changhua County is divided into two plains: Changhua Plain and the Zhuoshui River Alluvial Fan, separated by the Old Zhuoshui River.
