Kundalika River
The Kundalika is a small river flowing from the hills of Sahyadri to the Arabian Sea. This river originates at a small town called Bhira in the Indian state of Maharashtra, 150 km south east of Bombay (Mumbai). The important towns located on the banks of Kundalika are Kolad, Korlai, Chaul, Roha and Salav. Details River Kundalika is fed by the excess water from Tata Power's Mulshi Dam Project on to a series of hydroelectric projects and dams, including Ravalje followed by Bhira and then Dholvan, where the water is released in the morning typically at 6am. The gush of the water reaches Sutarwadi at 7:30am and water rises at Kolad at 10:00am. A historical trade route called Savalya Ghat descends in Kundalika Valley from Tamhini Ghat Road. Beautifully carved staircases exist at some places, and there are two small water cisterns. This river was a means of trade in ancient times. There are many forts on the hills along the river, including Surgad, Avchitgad, Birwadi fort, Kor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Korlai Fort
Korlai Fort is a colonial fort in the Raigad district of Maharashtra, India. Formerly a part of the Chaul in Portuguese India, the structure is a specimen of Portuguese colonial architecture. It was built as a companion to the fort at Chaul, at this strategic position the Portuguese could use it to defend their province which stretched from Korlai to the Fort Bassein. Vestiges of the Portuguese occupation are manifested in the distinct dialect of the Korlai villages inhabitants which is a Luso-Indian creole called Korlai Portuguese Creole. History This fort was built in 1521 by the Portuguese with the permission of the Ahmednagar sultanate. In 1521, taking advantage of the confusion in the aftermath of the death of the Burhan Nizam the Portuguese tried to take over the fort. However the sultan retaliated and sent some of his best men to reclaim the fort. Subsequently, a truce was reached in which the Ahmednagar sultanate occupied the island and no further fortification of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Maharashtra
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, ...

Raigad District
Raigad district (Marathi pronunciation: �aːjɡəɖ, previously Colaba district, is a district in the Konkan division of Maharashtra, India. The district was renamed to Raigad after the fort that was the first capital of the former Maratha Empire, which in turn was renamed from its earlier name - Rairi. The fort is located in the interior regions of the district, in dense forests on a west-facing spur of the Western Ghats of Sahyadri Range. In 2011 the district had a population of 2,634,200, compared to 2,207,929 in 2001. The name was changed in the regime of Chief Minister A. R. Antulay on 1 January 1981. In 2011 urban dwellers had increased to 36.91% from 24.22% in 2001. Alibag is the headquarters of Raigad district.

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Devkund Waterfall
Devkund Waterfall is a waterfall located near Bhira, in Raigad district, Maharastra, India. It is a 'plunge' waterfall pouring massive amounts of water on the rocky surface underneath. It is a popular spot for one day picnics. Location Devkund Waterfall is located in Bhira Patnus and since it went viral on social media, it has become extremely crowded and dangerous place. Several lives have been lost while amateurs try to visit this place on their own. It is the confluence of three waterfalls and is said to be the origin of Kundalika River. It is about a three-hour trek from base village along the dam backwater and through forest to reach this place known as ‘Devkund’. A major part of the trek goes through some semi-dried forests with the river running parallel and sometimes crisscrossing through the route. A guide is required to be taken during the trek as there is dense forest around. Commutation *Distance from Pune: 110 km *Distance from Mumbai: 170 km *Dist ...

Tailrace
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth. Some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a water wheel is called a mill race. The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace. Waterwheels were used for various purposes from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelton Wheel
The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energywhich made for a very efficient turbine. History file:Pelton wheel (patent).png, Figure from Lester Allan Pelton's original October 1880 patent Lester Allan Pelton was born in Vermillion, Ohio in 1829. In 1850, he traveled overland to take part in the California Gold Rush ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical cir ...

Revdanda
Revdanda is a village near Alibaug, Raigad District, Maharashtra. It's the site of the medieval 'Chaul harbor'. Directions India. It is connected through a coastal highway (Sagari Mahamarg) away from Alibag, away from Mumbai, 37km away from Roha and 33km away from Murud. Until a few years ago the coastal road that goes south from Alibag used to terminate at Revdanda where it encountered the Kundalika creek. A bridge now spans the creek and the whole stretch southward of Revdanda up to Murud-Janjira has now become accessible. Part of the town is situated within the premises of Revdanda fort, an old Portuguese fort. History The history of Revdanda and the surrounding villages are quite similar to Chaul, due to their close proximity to the town. Muslim Rule In 1490 the area fell under the Ahmadnagar Sultanate. Portuguese Era In 1505, Portuguese commander Dom Lourenço de Almeida defeated the Muslims and conquered the area around Chaul. In 1508, Venetian mercenaries along ...
