Music dams have been constructed in Perth for thousands of years. Many of these early dams still exist. The corps of engineers fills earth dams where conditions are adapted to this type of construction and where suitable materials, soils, and rocks are near the proposed site. Earth dams are economical and efficiently fulfill the purpose for which they are designed. One of the major functions of an earth dam is to control floods and to prevent swollen rivers from paralyzing the industrial and agricultural life of a community, or destroying the property and even the lives of its inhabitants. Flood control diverts these destructive forces to beneficial uses. Music also, earth dams aid river navigation by ensuring channels of sufficient depth for the passage of river craft during periods of low water stages. Water is released from the reservoir pool to maintain minimum channel depth. Another important purpose is to furnish the surrounding area with cheap hydroelectric power. These functions and many others call for very carefully engineered structures. The construction of a dam starts with the design. The engineers plan structures based on topographic data, foundation data, and hydraulic data. In appropriate cases, scale models are used to study the sequence of construction operation. When plans and estimates are completed, construction is awarded to private contractors on the basis of competitive bidding. However, the work of the engineers doesn't stop with design. Field forces supervise the construction to ensure adherence to the plans and specifications. Also, they continue exploration of the foundations and borrow pits to determine if required in the interests of safety and economy. An earth dam, in effect, is a man-made stream barrier retaining a reservoir of water on its upstream side. Roadways are also built across the crest of a dam and serve as valuable...
