Recommended: Importance of hydropower energy

What is Hydroelectric Power (H.E.P.)? Hydropower is the power/electricity, which is generated form energy of water flow. This source of power is considered to be renewable energy as it is constantly refilled due to the water cycle. In addition to the water cycle, hydropower is dependent upon stored gravitational energy. A rock on top of a hill contains potential energy because of its position. If a force pushes the rock, it rolls down the hill because of the force of gravity. Potential energy is then converted to kinetic energy until it reaches the bottom of the hill and stops.

HPE history: Humans have used the power of moving water for over 2,000 years. The first references to watermills are found in Greek, Roman, and Chinese texts. They described vertical waterwheels in rivers and streams. …show more content…

Small hydropower has been developed by many countries, especially the developing countries. Compared to large hydropower, it takes less time and efforts to integrate small hydro schemes into local environments. It has been increasingly used in many parts of the world as an alternative energy source, especially in remote areas where other power sources are not viable. These power systems can be installed in small rivers or streams with little or marginal environmental effect. Most small hydropower systems do not require the construction of a dam, but are rather run of river schemes. Small hydro in isolated systems may be also connected to grid, if available at a later date. Such integration with a grid shall improve the total benefits of hydropower projects and quantum shall be as per site-specific conditions. Comparative advantage of the small hydro has already resulted in a large number of these installations all over the world. The success of the small hydro option depends on careful selection and timely completion of the best sites. The redundancies in terms of stake are reduced. All

How Did Johnstown Flood

246 Words | 1 Pages

In the town of Johnstown they had steal industries that were booming, and it gave steady paychecks to the workers who worked really hard and long shifts of 12 hours long 6 days a week. Since the town was in a valley with hills surrounding it, it didn't have much of a chance if a flood ever occurred. But the people of Johnstown had no idea of the risk they were at. There was a man made lake that was held by a dam that was made of earth but it was so poorly built that it sagged in the middle and leaked, and it was not easy to release water if it ever became too full. In late May of 1889 came clouds of rain as it rained it filled up the reservoir.

Sacramento River Write-Up

263 Words | 2 Pages

Lab Write-Up The Sacramento River, a meandering river located in Northern California, appears to have changed significantly from 1998 to present day. The winding curves of the river were much more pronounced and dramatic until erosion and decomposition affected the sediment amount in the river, changing its shape. As it flows, it deposits sediment on banks that lie on the insides of curves (point bar deposits), and erode the banks on the outside of curves. The low, crescent-shaped deposit of sediment on the inside of a meander is a point bar, which is spotted several times in the river. It is a feature of erosion that shapes the river into its current form.

Atchafalaya River Research Paper

3137 Words | 13 Pages

It was running at about twelve miles an hour significantly faster than the Yukon after breakup and it was pounding into the so-called stilling basin on the downstream side, the least still place you would ever see. There was a high sill next to this one a separate weir, two-thirds of a mile long and set two feet above the local flood stage, its purpose being to help regulate the flow of extremely high waters. The low sill, as the one we stood on was frequently called, was the prime valve at Old River, and dealt with the water every day. In the mid-sixties, a man alone had come down from Wisconsin in a small double-ended vessel with curling ends and tumblehome a craft that would not have been unfamiliar to the Algonquians, who named the Mississippi. A towboat coming up the Atchafalaya may be running from Corpus Christi to Vicksburg with a cargo of gasoline, or from Houston to St. Paul with ethylene glycol.

Columbia River Plateau

1086 Words | 5 Pages

In the winter, the river flows at about 1,700 cfs due to the glacial runoff and in the summer the flow decreases as the temperature increases. Since meandering channels form on low slopes, the velocity is low and must flow through easily eroded bedrock which would be low sediments. The strongest current is on the cut bank where the larger rocks settle and in the point bar, where the slowest velocity occurs, is where deposition of small sediment falls. The river has low energy and therefore is a wide valley where the energy is directed side by side and eventually forms the meandering
