This course explores the fundamental principles of hydroelectric dams, including their design, operation, and the process of converting
GATE : A dam gate is used to control the flow of water in a dam by regulating the amount of water that flow into or out of the reservoir. 2.
The hydraulic design of dams is essential for managing water flow and pressure to ensure safety and efficiency, preventing structural failures and
This diagram illustrates the basic working principle of a hydroelectric dam, which harnesses the energy of flowing water to generate electricity
One of the most important things for realising river-based hydropower electricity generation is sufficient gravitational potential energy and kinetic energy.

The general data presented in sections two and three gives an idea of the extreme diversity of the millions of very large or very small dams worldwide. Dam design and construction methods for the most usual types of large dams are presented and justified in section four. The possibility and usefulness of building as many dams in the 21st century as have been built in the 20th is analyzed in section six. 4 Dam Design and Construction. – Ninety-seven percent of this total storage is created by the “large dams.” As classified by International Commissions on Large Dams (I.C.O.L.D.), large dams include the 40 000 dams higher than 15m and a few thousand lower dams with storage of over 3 million m3. – Two percent of the total storage is created by over 150 000 small dams (5 to 15m high) with reservoirs between 100 000 and 3 million m3.

A **dam** is a structure that impounds or restricts the flow of water. Dams are classified into four basic types: gravity dams are massive structures made of concrete or masonry that rely on their weight to resist the force of impounded water; embankment dams are large earthworks "Earthworks (engineering)") consisting of rocks, clay, sand, soil, or gravel; buttress dams consist of a sloped, concrete face supported on the downstream side by a series of triangular buttresses; and arch dams use a curved concrete wall to transfer the weight of the water to the surrounding valley walls. Irrigation is a critical application of dams: about 20% of the world's arable land is irrigated using water from reservoirs impounded by dams.
* Dams Are a Vital Part of the National Infrastructure. The purpose of a dam is to impound (store) water, wastewater or liquid borne materials for any of several reasons, such as flood control, human water supply, irrigation, livestock water supply, energy generation, containment of mine tailings, recreation, or pollution control. Manmade dams may be classified according to the type of construction material used, the methods used in construction, the slope or cross-section of the dam, the way the dam resists the forces of the water pressure behind it, the means used for controlling seepage and, occasionally, according to the purpose of the dam. **Embankment Dams**:Embankment dams are the most common type of dam in use today. The ability of an embankment dam to resist the reservoir water pressure is primarily a result of the mass weight, type and strength of the materials from which the dam is made.
