Dams of India have been built across many perennial rivers since the independence of India. These dams in India are a part of several multi-purpose projects to serve a variety of needs. In a multi-purpose project‚ a river forms a unit and a river valley is developed‚ by exploiting all the resources of the river. Basically‚ dams are built to harness the river water so that it can be utilised according to the needs. A multipurpose project is launched often for storing water for irrigation purposes

A dam is a barrier that impounds water or underground streams. Dams generally serve the primary purpose of retaining water‚ while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. Hydropower and pumped-storage hydroelectricity are often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations.

Irrigation and it’s Methods Irrigation may be defined as the science of artificial application of water to the land or soil. It is the replacement of rainfall with water from another source in order to grow crops. Several methods of irrigation are used today depending on the water availability and the type of crop to be irrigated. Some of these methods are: 1) Flood irrigation: In flood irrigation‚ a large amount of water is brought to the field and flows on the ground among the crops

METHODS OF IRRIGATION The manner in which water is applied to the land is commonly referred to as method of irrigation. These methods are adopted to apply irrigation water to the crop depending on the landscape‚ amount of water and equipment available‚ the crop and method of cultivation of crop. The main aim of these methods is to store water in the effective root zone uniformly and in maximum quantity ensuring minimum water loss and to get optimum yield. Various methods of irrigation are: 1. Surface

Hydroelectric Dams Introduction In this Alternative Energy Project you are going to read about Hydroelectric Dams‚ and learn how Hydroelectric Dams work. You will also be reading the disadvantages and advantages of hydroelectric dams‚ and more. How does Hydroelectric Dams work? Hydroelectric Dams works by letting the energy of the water flow turn into an electric voltage. Then water goes through a series of turbines‚ then the water makes the turbines turn‚ and then it creates electricity

ABSTRACT The main objective of this essay was to evaluate the impact of dams on the economic‚ social and environmental contexts. The idea was to analyse the dam’s major impact on each of these aspects. In the economic background‚ the benefits that hydroelectric dams provide were discussed in addition to the dam’s economic role in agriculture and food supply. Next‚ social impacts of dams were assessed which were mostly negative that dealt with population displacement and cultural sites destruction
