A water wheel is a machine for converting the kinetic energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wheel (usually constructed from wood or metal), with numerous blades or buckets attached to the outer rim forming the drive mechanism. Water wheels were still in commercial ...
In the Malkus waterwheel, a constant flow of water pours in at the top bucket of a simple circular symmetrical waterwheel and the base of each bucket is perforated to allow the outflow of water. At low rates of inflow, the wheel rolls permanently in the same direction.
The norias discharge water into aqueducts built on tall stone arches. To catch the water, each aqueduct has a very short section parallel to the water wheel and the river. This joins at 90 degrees the main section of the aqueduct, which leads away from the river and was sometimes many hundreds of metres long. [12]

The undershot water wheel and overshot water wheel, both animal- and water-driven, and with either a compartmented body (Latin tympanum) or a compartmented rim, were used by Hellenistic engineers between the 3rd and 2nd century BC. [11] In 1st century BC, Roman architect Vitruvius described the function of the noria. [12]
These include all three variants of the vertical water wheel as well as the horizontal water wheel. [6] Apart from its main use in grinding flour, water-power was also applied to pounding grain, [7] crushing ore, [8] sawing stones [9] and possibly fulling and bellows for iron furnaces. [10]

The software provides tools to automate various basic and advanced delineations, calculations, and modeling processes. [9] It supports river hydraulic and storm drain models, lumped parameter, regression, 2D hydrologic modeling of watersheds, and can be used to model both water quantity and water quality.
