What are multi-purpose river projects explained in class 7 Geography?

Archaeological and historical records show that from ancient times we have been constructing sophisticated hydraulic structures (Sringaverapur near Allahabad, dams, lakes, and irrigation systems during the time of Chandragupta Maurya, Bhopal Lake, and the tank in Hauz Khas, Delhi) like dams built of stone rubble, reservoirs or lakes, embankments and canals for irrigation.

Adam is a barrier across flowing water that obstructs, directs, or retards the flow, often creating a reservoir, lake, or impoundment. "Dam" refers to the reservoir rather than the structure. Dams are classified according to structure, intended purpose, or height. Based on the structure and the materials used, dams are classified as timber dams, embankment dams, or masonry dams, with several subtypes. According to the height, dams can be categorized as large dams and major densely as low dams, medium height dams, and high dams.

A dam or a series of dams are built on a river and its tributaries to solve various purposes. Purposes solved through a Multi-Purpose River Project are:

1. Control flood and drought.
2. Checks soil erosion.
3. Provides water for irrigation, drinking and industrial purposes.
4. Generates Electricity.
5. Provides inland navigation.
6. Provides facilities for recreation.
7. Preservation of wildlife, forests and development of fisheries.

Jawaharlal Nehru proudly proclaimed the dams as the `temples of modern India'; the reason being that it would integrate the development of agriculture and the village economy with rapid industrialization and growth of the urban economy.
