Endeavor to change the course of history, has always been a primary motive of human civilization, through several centuries. It has been observed throughout history, that several times people have tried to undertake a feat which brings them in direct face-off with nature. May it be the intent to master the air by inventing airplanes, building mega-structures such as pyramids, or even stopping the flow of one of the world’s largest water resources, “The Niagara Falls”.
Niagara Falls consists of Horseshoe Falls and the American Falls. Due to several years of rocks falling in, between the year 1931 and 1954, the American Falls faced erosion, which if not prevented would have resulted in the permanent extinction of the American Falls. With resulting public outcry and protests to save the American Falls, the United States Army Corps of Engineers (USACE) – Buffalo district was encumbered with the immense responsibility of dewatering the American Falls for repairs. Taking up this historic challenge, a cofferdam was constructed, that took 3 days after working in two 11-hour shifts, resulting in cutting off of the flow of the Falls from 60,000 gallons per second to one-fourth of its capacity of 15,000 gallons per second.
