Describe Three Benefits and Three Costs of Damming Rivers

Dams provide a range of economic environmental and social benefits including recreation flood control water supply hydroelectric power waste management river navigation and wildlife. The purpose of this lesson is to encourage students to look at a complex issue from differing viewpoints and to reach a decision on its merits after examining multiple points of view.

What Are The Advantages And Disadvantages Of Dams Quora Greenhouse Gases Essay Energy Transformations

Hydroelectricity means clean and cheap energy for today and for tomorrow.

. Creating a reservoir means a large area must be flooded often prime riverside land. This lesson will allow students to evaluate the costsbenefits of the Three Gorges Dam project on the Yangtze River in China. Coral reefs are being degraded through a process known as coral bleaching.

Compare and contrast the main types of freshwater ecosystems. Edwards Dam is small compared with other dams recently under consideration for removal. Name and describe the major zones of a typical pond or lake.

Downstream of a dam the river is starved of its structural materials and cannot provide habitat according to the Hydropower Reform Coalition a collection of. Electricity is produced at the constant rate with the help of hydroelectricity or hydroelectric power. Some of the advantages are.

Coral bleaching occurs when coral are stressed most commonly by an increase in ocean surface temperatures and pollution. They also absorb wave energy which protects our shorelines. How much less CaCO3 in kg is expected to be deposited in 2050 than would be deposited if ocean water pH were to remain at its current value.

They provide activities like fishing boating swimming camping and hiking. Three Gorges Dam can efficiently store the water from upper stream and reduce the flood during the flood season. Flood control is a vital Three Gorges Dam benefit.

Describe three benefits and three costs of damming rivers. Pros of dams. ANS- The costs and benefits of Damming Rivers has been briefly ststed below.

Barges and ships can navigate along a river carrying large loads of food and merchandise. The World Commission on Dams estimates that 40-80 million people have been displaced by dam construction in living memory. Flood control and protection of low lying areas during heavy rainfall.

BENEFITS- A dam Helps us to retain our water supply when we dam a river water is pool to form a reservoir behind the structure of the dam due to this population around. Tourism and Tourist spots are developed. This style of transportation is effective because the loads carried can be quite large.

Since ancient time Yangtze River floods have been disasters to people especially in the section of Hubei province and Dongting Lake area. In general damming rivers and installing hydropower turbines permanently alters the environment and disrupts naturally functioning ecosystems. The state uses an interest rate of 5 for flood protection.

Hydroelectric power is created when water passes through a dam via a turbine. For example populations of wild salmon and trout which migrate back and forth between upstream spawning grounds and the ocean have fallen off by as much as 90 percent in parts of the US. Due to the damming of.

Advantages of Dams Advantages of dams are numerous that is the reason so much money and work goes into building and maintaining them. There are also increased health risks associated with the construction of large dam and reservoir systems especially in tropical and sub-tropical areas where the disruption of the natural drainage ecologies provides fertile ground for the growth of. Increasing the dams height will 1 reduce a floods probability 2 reduce the damage when floods occur and 3 cost more.

Mainly Hydroelectricity power is generated which is reliable than wind and solar energy. Creates a reserve of water for drinking and irrigational purpose. During drought conditions water stored in dams can be used.

Dams for all their attractive benefits are saddled with an overflow of negative impacts. Hydroelectricity is one of the most studied forms of alternative energy as it is relatively reliable and stable and most hydroelectric power plants have low. Some of those costs include a negative impact on the natural ecosystem risk of flooding which can result in relocating nearby residents and costly repairs as dams age.

It offers a vast potential and is available where development is most necessary. With an average lifetime of 50 to 100 years hydroelectric developments are long-term investments that can benefit various generations. A costbenefit study concluded that necessary structural repairs would have cost 17 times the cost of removing the dam and restoring anadromous fish passages ARFETU 1999.

Up to 24 cash back Because of ocean acidification it is expected that in 2050 the mass of CaCO3deposited annually in coral reefs will be 20 percent less than is deposited currently. Coral reefs promote a high level of biodiverse sea life. One of the most beneficial aspects of dams is the potential to create hydroelectric power.

What particular environmental health and social concerns. Dams provide for drinking water generate electricity and facilitate irrigation which is beneficial. Rivers and streams provide a great opportunity for transportation.

However as with most things building dams can comes with its costs. Which dam height minimizes the expected total annual cost.
