Answer: The history of American Indians before European contact is broadly divided into three major periods: the Paleo-Indian period, the Archaic period (8000–1000 b.c.), and the Woodland period (1000 b.c.–1600 a.d.). The limited evidence available about the Paleo-Indian period suggests that the first Indians in the Southeast, as elsewhere, were nomadic, hunting and defending themselves with stone tools (knives and scrapers), clubs, and spears, which were at times tipped with wellcrafted, fluted stone points. During the Archaic period, basketry, bone tools, and finer stone tools appeared. Archaic peoples also began to develop more specialized knowledge of their local environments and the animals and plants that lived there. Though they did not generally travel far beyond these familiar environments, American Indians during this period did begin to establish trade and migration routes that brought the native peoples of the Carolinas in contact with other bands and tribes.
Himalayan Rivers contain large quantities of sediment with hard abrasive particles, which is a hurdle for the economic exploitation of hydropower resources. The design and operation of headwork components in hydropower plants can only manipulate sediment particle size and hence only sediment concentration in the water.
