Topic 1-SP 1A-Auburn Dam Cost Read the article affached which discusses the history and coat of Auburn Dantastof Sacent) on the American River (Tempting tate: A toment of doubts, Matt Weser)

The article state the cost of Auburn Dam is going to be about $5 billion $5 x 10%) and will impound 2.3 monace-tof water reservoir capacity, not the analyield. This is the cost toplan, design, and construct the denie.Austul parameter to estimate the cost of a dam is the size of the reserva impounded behind the dam possible to express the cost of the dama Sacre-ft of reservoir capacity. This is the first cond" or the capital coaf as you will be learning in Engineering Economics. In Engineering Economics we have to ask ourselves ‘n spending $5 billion a worthwhile experi economically atractive? Do the time benefits exceed the cost of the dare?" To aver the questions we need to identify the benefits and assign a cost for the benefits. For a water resource project, this is trequently the amount of water the dam and reservoir will yield, (usually acte-fy) or the value of the electric energy sy KW-year generated by the dam's hydroelectric turbines. The water han value and can be sold to water agencies, the electric power can be sold to power companies. Both will in tam sell to customers, the yoursel The amount of water generated annually (on the average, became one your indiferent from the next) is called the annual yield. This is NOT the size of the reservar, but only a small portion of the reservar. For the Autumdam and reservoir, the yield is 350,000 acre-flyour. Note that the average annual river tow at the care ai 16 x 10 million acre-yr. but most of the river flow is owned by other water agencies through long-term water rights. As a result, only 350,000 acre-your is available for auntamen a. Assuming the project cost of Aubum Dam is $5 billion and the reservat capacity is 2.3 million acre-t, as stated in the article, determine the Aubur Dam project cast in terms of $perace-of reserva storage There is a list of 5 dam and their costs at the end of the Welser article, the top: 3 have been built the est two have not; those are just states of coat." Se reserva is currently under consideration by a number of agencies in Southern Cali b. Determine the cast of the dam and reservoir, in terms of $ per acre-ft of storage for the five dama Inted at the end of the article. Compare the castinal to the per acre- of storage for the five da anders in the cost of the Aubum Damable compared to the other das and reservoirs? If you do, explain your reasoning if you do not explain your ring c. If the economic life of the Autum Dan will be 50 years, how much water acre), based on the annual average of 350,000 acre-year can be produced by the Autumn darn over its economic d. If we were to do a very simple economic analysis, not considering the time value of money or the operation and maintenance cost to keep the facility operating, determine the cost of the water produced, $acre-, based on the economic life of the dar, its original cost of $5 billion, and the total amount of water which the dam and reservoir will produce over its 50-year late? Crics have said the cost of water from Aubum dam is just too expensive.
