ABSTRACT

PAGE 12.10. 1887 Syracuse NE/USA 23.03. 1955 Denver CO/USA John Chatfield Page obtained the BS degree from University of Nebraska, Lincoln NE, and the MS degree in 1911 from Cornell University, Ithaca NY. After work as a topographer with the US Bureau of Reclamation USBR he became in 1909 city engineer of Grand Junction CO. From 1911 to 1925 he was junior engineer with USBR, Denver CO, then until 1930 superintendent of the Grand Valley Project in Colorado, involved in the design of Boulder Dam until 1935, from when he was acting commissioner until 1943, finally retiring as consulting engineer at Denver CO. Page had been connected to irrigation work in Western US almost all through his professional career. In 1935 he was transferred to Washington DC to head up the USBR Engineering Division following Elwood Mead (1858-1936). Under Page’s direction the Bureau carried forward the Colorado River Project as well as such large work as the Central Valley Project in California, and the Columbia Basin irrigation and power projects in Washington State. The main dams on which Page was involved were Hoover Dam, Grand Coulee Dam, and Marshall Ford Dam. Due to ill health, Page resigned in 1943 as commissioner, but continued as a consultant until 1947. He was elected in 1953 Honorary Member ASCE. A memorial to the late Page was unveiled at his namesake city Page AZ in 1964, located two miles from Glen Canyon Dam, consisting of a low concrete platform, a flagpole and a bronze mounted on the block of polished granite.

PALMER 20.01. 1878 Berkeley CA/USA 08.12. 1960 Los Angeles CA/USA Harold King Palmer received his education from the University of California, Berkeley CA, with a BS degree in 1898, and the PhD degree in 1903. He was a fellow assistant of an observatory from 1898 to 1906, including two years in a branch observatory in Chile, and a computer of the San Joaquin Kings River Canal & Irrigation Co. from 1907 to 1908. From 1909 to 1925 he was a junior, assistant and engineer of the US Indian Irrigation Service, from when he was a designer and chief draftsman of its Office Engineer. Palmer was member of the American Society of Civil Engineers ASCE, and the National Geographical Society. Palmer’s name has been particularly connected to a design made to measure discharge in sewers of circular shape. Whereas the original design of Ralph Leroy Parshall (18811959) was applied in open channels, the Palmer-Bowlus design applies to closedconduit conditions. Both are essentially based on the critical flow theorem, by which the transition from sub-to supercritical flow is forced by a channel contraction. This basic hydraulic principle allows for discharge determination with only one depth reading upstream of the contraction. The Palmer-Bowlus flume was perfected by Wells and Harold Benedict Gotaas (1906-1977), and an improved portable version was recently fabricated in Japan. The discharge coefficient varies only within a small range, and the modular limit undergoes an only small variation, rendering the device practical. Anonymous (1941). Palmer Harold K.
