Big Dams

When the dam decides to use river resources, the government is faced with problems such as land use, energy production, use of natural resources. Dam reveals the dilemma faced to meet the needs of many confrontational human race and planning these important projects can support the growing population of the earth ecologically It must function for a sustainable system. INTRODUCTION In recent years, the United States has demolished many dams and has formulated plans for large hydroelectric dams in developing countries.

Not all dams cause enormous damage, but over 45,000 dams all over the world are causing huge damage. World dumb committees supported by the World Bank estimate that from 40 to 80 million people were exiled from the dam with the support of dam supporters and critics. 60% of the length of the world's large river system is at least moderately or seriously confused by the dam and the irrigation water associated therewith. Large scale reconstruction of rivers in the world is the main cause of the rapid decline of freshwater species. Approximately one-third of freshwater fish is classified as being on the verge of extinction or being vulnerable. Important but unknown proportions of shellfish, amphibian, plant and birds dependent on freshwater habitats are also in danger of extinction

So then why are there too many dams built in the rivers of the world? When the dam was compared with the alternative, there was no equal stadium ever. In government and enterprise, the corruption and the power of encouraging dams means that the feasibility study of the new dam often underestimates its expense and exaggerates its interests. If a comprehensive, transparent and participatory assessment of water and energy demand options is made, there are few large dams that can achieve this level. There is no doubt, this is a major factor in the scream, including such assessment against the World Commission's recommendations on dams by the dam.

The engineers of the regeneration engineers are looking forward to the design of this huge dam. By this time they are one of the most knowledge-rich and experienced dam builders in the world, even though they have never done such big things. Hoover Dam will be the world's tallest dam far than the dams ever constructed. The lake it creates will be the world's largest lake. The proposed dam is too expensive, the pressure on the water is high, and many people are worried. They are not sure if Reclamation engineers have sufficient knowledge and experience to make the dams strong and secure. Others want to know if the expected benefits are sufficient to justify the enormous cost. Despite these problems planning and design continues
