Clemens Herschel
Clemens Herschel (March 23, 1842 – March 1, 1930) was an American hydraulic engineer. His career extended from about 1860 to 1930, and he is best known for inventing the Venturi meter, which was the first large-scale, accurate device for measuring water flow. He developed this device while serving as director of the Holyoke Testing Flume, a turbine testing facility which he would redesign, which became the first modern hydraulics laboratory in the United States and the world. Early life and education Clemens was born in Vienna on March 23, 1842 to Samuel and Therese Hirschl (née Kohn). His family immigrated to Davenport, Iowa in 1850. He spent most of his life practicing his profession in Massachusetts, New York and New Jersey. He attended Harvard University, where he received his bachelor of science degree in 1860 from the Lawrence Scientific School.''New York Times.'' "Clemens Herschel Dies in 89th Year."

Giovanni Battista Venturi
Giovanni Battista Venturi (11 September 1746 – 10 September 1822) was an Italian physicist, savant, man of letters, diplomat and historian of science. He was the discoverer of the Venturi effect, which was described in 1797 in his ''Recherches Experimentales sur le Principe de la Communication Laterale du Mouvement dans les Fluides appliqué a l'Explication de Differens Phenomènes Hydrauliques'', translated into English by William Nicholson as "Experimental Inquiries Concerning the Principle of the Lateral Communication of a Motion in Fluids," and published in 1836 in Thomas Tredgold's ''Tracts on Hydraulics''. Because of this discovery, he is the eponym for the Venturi tube, the Venturi flow meter and the Venturi pump. Career Born in Bibbiano, Italy, in the Province of Reggio Emilia Giovanni was a contemporary of Lagrange and Laplace, and a pupil of Lazzaro Spallanzani. He was ordained as a priest in 1769, at the age of 23, and in the same year was appointed as teacher of l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institution Of Civil Engineers

Thompsonville, Connecticut
Thompsonville is a census-designated place (CDP) in the town of Enfield in Hartford County, Connecticut, United States. The population of the CDP was 8,577 at the 2010 census. History Thompsonville was established in the 19th century as a carpet-manufacturing community. Orrin Thompson, from whom the community takes its name, built a dam across Freshwater Brook in 1828 and opened the first carpet mill in 1829. Thompson's first mill, named "White Mill", employed skilled weavers brought from Scotland. Initially its product was largely flat-woven ingrain carpeting, an inexpensive type of carpeting, but over time it added more expensive weaves, such as three-ply ingrain and loop brussels. The mill had 230 looms in operation as of 1846. Carpeting continued to be manufactured in Thompsonville until 1971, by which time most production had shifted to the southern United States. Geography According to the United States Census Bureau, the CDP has a total area of , of which is land and , o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New York City Water Supply System
A combination of aqueducts, reservoirs, and tunnels supplies fresh water to New York City. With three major water systems ( Croton, Catskill, and Delaware) stretching up to away from the city, its water supply system is one of the most extensive municipal water systems in the world. New York's water treatment process is simpler than most other American cities. This largely reflects how well protected its watersheds are. The city has sought to restrict development surrounding them. One of its largest watershed protection programs is the Land Acquisition Program, under which the New York City Department of Environmental Protection (DEP) has purchased or protected, through conservation easement, over since 1997. With all the care given, the city's water supply system is partially exempted from filtration requirements by both the federal and the state government, saving more than "$10 billion to build a massive filtration plant, and at least another $100 million annually on it ...

Niagara Falls
Niagara Falls () is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the province of Ontario in Canada and the state of New York in the United States. The largest of the three is Horseshoe Falls, which straddles the international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island and from American Falls by Luna Island, with both islands situated in New York. Formed by the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls have the highest flow rate of any waterfall in North America that has a vertical drop of more than . During peak daytime tourist hours, more than of water goes over the crest of the falls every minute. Horseshoe Falls is the most powerful waterfall in North America, as measured by flow rate. Niagara Falls is famed for its b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rockaway River
The Rockaway River is a tributary of the Passaic River, approximately 35 mi (56 km) long, in northern New Jersey in the United States. The upper course of the river flows through a wooded mountainous valley, whereas the lower course flows through the populated New Jersey suburbs and former industrial area west of New York City. It drains an area of approximately 130 sq mi (340 km²). It rises in the Oak Ridge neighborhood of Jefferson Township. It flows SSW, in a direct course between in the valley between the mountain ridges. Northeast of Wharton it emerges from the mountains and flows generally east in a meandering course, past Wharton, Dover (where it enters a concrete channel), Rockaway, Denville and Boonton, where it passes through the Boonton Gorge. The gorge begins with the impressive 25 foot Boonton Falls. It continues for a little over 1 mile (1.6 km) dropping around through nearly continuous class 3 and 4 whitewater. On the south s ...
