Reservoir
A reservoir is partly artificial lake for storing water. Building an embankment or to preserve a supply of water for is an ancient practice. In building artificial lakes for a municipal water supply it is necessary to consider the amount and distribution of rainfall, evaporation, soil or rock conditions, and elevation. The ground of the reservoir may be naturally impervious enough to prevent excessive seepage, or a clay or other lining may have to be built.
Reservoirs are also built on the headstreams of or along the rivers to aid in flood control, on canals to maintain water level for navigation, and to ensure water supply for hydroelectric plants. Some reservoirs are built on the tributaries of large rivers to act as catch basins for silt.
They form the utilization of water resources. The need for reservoirs is caused by the great unevenness in the distribution of river discharge during the course of the year, as well as its unequal territorial distribution. Reservoirs may have diurnal, weekly, seasonal (or yearly), and even longer periods of regulation.
