TIFF Sidescan-Sonar mosaic of Lake Mohave : UTM, Zone 11, NAD83 Projection

Lake Mohave is one of several multi-purpose reservoirs that have been constructed on the Colorado River. The lake was formed upon completion of the Davis Dam in 1953. No mapping of the floor of the lake had been conducted since completion of the Davis Dam. The U.S. Geological Survey, in cooperation with researchers from the University of Nevada Las Vegas, completed a geophysical survey of this lake in April 2002. The survey included collection of sidescan sonar imagery of nearly the entire lake floor, and high-resolution seismic-reflection profiles along widely spaced lines throughout the lake. The detailed mapping of the lake floor was used to determine the amount of sediment that had accumulated in the lake since impoundment, its distribution, and the processes of deposition.

莫哈韦湖（Lake Mohave）是科罗拉多河上修建的多用途水库之一。该湖于1953年戴维斯大坝（Davis Dam）竣工后形成。自戴维斯大坝建成以来，尚未开展过该湖湖床的测绘工作。美国地质调查局（U.S. Geological Survey）与内华达大学拉斯维加斯分校（University of Nevada Las Vegas）的研究人员合作，于2002年4月完成了该湖的地球物理勘测。本次勘测涵盖了几乎全湖湖床的侧扫声呐影像（sidescan sonar imagery）采集，以及沿全湖范围内间距较大的测线获取的高分辨率地震反射剖面（high-resolution seismic-reflection profiles）。此次精细湖床测绘被用于确定该水库自蓄水以来的沉积物蓄积量、分布特征及沉积作用过程。
