Elementary Cellular Automaton. The simplest class of one-dimensional cellular automata. Elementary cellular automata have two possible values for each cell (0 or 1), and rules that depend only on nearest neighbor values.
TVA's hydroelectric system consists of: 29 power-generating dams throughout the Tennessee River system, some of which date back to the TVAâs early days in the 1930s. A pumped-storage plant near Chattanooga called Raccoon Mountain. Purchased power from eight dams on the Cumberland River operated by the Army Corps of Engineers.
Early dam building took place in Mesopotamia and the Middle East. Dams were used to control the water level, for Mesopotamia's weather affected the Tigris and Euphrates rivers, and could be quite unpredictable. The earliest known dam is the Jawa Dam in Jordan, 100 kilometres (62 mi) northeast of the capital Amman. dry dam also known as a flood retarding structure, is a dam designed to control flooding. It normally holds back no water and allows the channel to flow freely, except during periods of intense flow that would otherwise cause flooding downstream.
