> The Niagara Falls are voluminous waterfalls on the Niagara River, straddling the international border between the Canadian province of Ontario and the U.S. state of New York. The falls are 17 miles (27 km) north-northwest of Buffalo, New York and 75 miles (120 km) south-southeast of Toronto, Ontario, between the twin cities of Niagara Falls, Ontario, and Niagara Falls, New York.
Niagara Falls is composed of two major sections separated by Goat Island: Horseshoe Falls, the majority of which lies on the Canadian side of the border, and American Falls on the American side. The smaller Bridal Veil Falls are also located on the American side, separated from the main falls by Luna Island.
Niagara Falls were formed when glaciers receded at the end of the Wisconsin glaciation (the last ice age), and water from the newly-formed Great Lakes carved a path through the Niagara Escarpment en route to the Atlantic Ocean. While not exceptionally high, the Niagara Falls are very wide. More than six million cubic feet (168,000 m³) of water falls over the crest line every minute in high flow, and almost 4 million cubic feet (110,000 m³) on average. It is the most powerful waterfall in North America.
The Niagara Falls are renowned both for their beauty and as a valuable source of hydroelectric power. Managing the balance between recreational, commercial, and industrial uses has been a challenge for the stewards of the falls since the 1800s.
> Characteristics : Niagara Falls is divided into the Horseshoe Falls and the American Falls. The Horseshoe Falls drop about 173 feet (53 m), the height of the American Falls varies between 70-100 feet (21 m) because of the presence of giant boulders at its base. The larger Horseshoe Falls are about 2,600 feet (792 m) wide, while the American Falls are 1,060 feet (323 m) wide.
The volume of water approaching the falls during peak flow season may sometimes be as much as 202,000 cubic feet per second (5,720 m³/s). Since the flow is a direct function of the Lake Erie water elevation, it typically peaks in late spring or early summer. During the summer months, 100,000 cubic feet per second (2,832 m³/s) of water actually traverses the Falls, some 90% of which goes over the Horseshoe Falls, while the balance is diverted to hydroelectric facilities. This is accomplished by employing a weir with movable gates upstream from the Horseshoe Falls. The Falls flow is further halved at night, and during the low tourist season in the winter, remains a flat 50,000 cubic feet per second (1,416 m³/s). Water diversion is regulated by the 1950 Niagara Treaty and is administered by the International Niagara Board of Control (IJC).
Viewpoints on the American shore generally are astride or behind the falls. The falls face directly toward the Canadian shore.
> The Future of Niagara Falls :
The future of Niagara Falls is not easily predicted. The Falls of Niagara as we know it today will remain as it is for thousands of years to come.
Erosion is the largest factor which will alter its appearance in the future. Some have estimated that the Falls would continue eroding southward for the next 8,000 years at which time it would reach the limits of Lake Erie.
The eastern seaboard of North American is today still rising from the glacial rebound effect. It has been suggested that as the land rises on the eastern seaboard that water flow to the ocean will slow and reverse so that in the future the Falls would be much diminished or cease to exist entirely.
Perhaps the most realistic outlook is that the Falls will continue to erode southward. There is no doubt that at some point in its future that the main Horseshoe Falls once it has eroded far enough south, will cut off the water flow to the American Falls. The Falls of Niagara will once again become one.
The greatest threat to the integrity of the Horseshoe Falls and the American Falls is rock falls. The American Falls has been the victim of many rock falls in the past. As the rock talus collects at the base, it reduces the distance of the water fall and creates more of a cascade effect.
In the future substantial rock falls may affect the appearance and change the Falls of Niagara to mere water cascades and/or rapids.
