Kuhls are built along the hill gradient for maintaining proper gravity for irrigation and running water mills (Fig. 2.7a & b). Wooden water channels are also used for running water-flour mills. These wooden channels are generally made by making notches at the natural water sources and the water is diverted to the water mill, using the natural gravitational flow of water. Since the topography of the area consists of very high slopes and rocky terrain's, wooden water channels are used at many places as water passes from one place to another.
Granite stones are used for grinding food grains. Long wooden channel placed at steep gradient is used for maintaining the high speed of the water flow. This is necessary for maintaining the high speed of the water mills wheel (Fig. 2.7a/b).
Now a days water mills are very rare. Water mill technology is in an extinct stage, because of power supply availability and less grain production. Food is purchased from cooperative societies or private shops now a days.
