Water wheels were most often used to power different types of mills. A combination of the water wheel and mill is called a watermill. An early horizontalwheeled watermill used for grinding grain in Greece was called the "Norse Mill." In Syria, watermills were called "noriahs." They were used for running mills to process cotton into cloth.
