The Effects of Dam Construction on the Trinity River Those working in Watershed management know there is little doubt these days that dam construction on our nation’s waterways is having a detrimental effect on rivers and their associated ecosystems. Many of the harmful effects created by dams are not always perceivable to the untrained observer‚ nor can they be observed on a temporal basis since changes to stream morphology may occur over a span of a few years‚ to hundreds and even thousands

(2010-MC-54) What is Hydroelectric power? Renewable source of energy It is renewable because the process takes nothing away from the environment . Advantages 1. Flexibility 2. Low power costs The major advantage of hydroelectricity is elimination of the cost of fuel. No import of fossil fuel is required. The average cost of electricity is less. Long economic lives. Low cost of labor. 3. Suitability for industrial applications While many hydroelectric projects supply

Hydroelectric The Hoover Dam does more than attract tourist‚ it provides power to 8 million people (32). Instead of using a heat source to create steam to turn a turbine like most power plants‚ hydroelectric plants use the natural flow of water and divert it through a turbine via a dam. The estimated available hydro energy in the United States‚ discounting wilderness preserves and the likes‚ is 65 gigawatts. One significant advantage of hydroelectric power in the U.S. is that there are existing

INTRODUCTION In hydroelectric power plant‚ turbine been used to generate power from reservoir of water. Turbine been selected by their characteristic curves based on the potential energy available in the water and the amount of power to be generated. Turbine is a type that develops torque by reacting to the pressure or weight of a fluid. The operation of reaction turbine can be describes by the Newton’s third law of motion that is for every action‚ there is an equal and opposite reaction. In this

A grand scheme that the Brazilian Government used was to build a dam in 1984. It was the fourth largest dam in the world and it cost 5 billion dollars. The Brazilian government plans to build more dams in the amazon to harness the power of various rivers with money borrowed from other countries. The idea of dams such as these is to generate cheap electricity for Brazilian industrustys. The water held back by the dams has flooded a huge area of forest. The forest wasn’t cleared‚ (though it should
