The U.S. has more than 87,000 dams greater than six feet high (and two million overall). While many dams continue to provide benefits such as flood control, irrigation, and water supply, for other dams the cost of maintenance or the negative effects on communities, fish, and tribes justifies their removal.
Dam owners and regulators decide whether to remove a dam by weighing many factors including: the cost of removal and the ability to replace any lost power generation against avoided long-term maintenance; safety concerns; benefits to endangered fish populations; increased recreational and commercial fishing; and restoration of cultural values of nearby tribes.
By 2020, roughly 70% of dams will be more than 50 years old, inviting us to reconsider the value to the public of long-term investments in this infrastructure.
Landslides along cut banks are common; a landslide along a cut bank affects the discharge of a river because the landslide the discharge would increase because the cross-sectional area of the river would increase.
Landslides are resulting from disturbances in the herbal stability of a slope. They are able to accompany heavy rains or comply with droughts, earthquakes, or volcanic eruptions. Mudslides broaden while water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.
The cross-sectional area is the place of a -dimensional form that is obtained while a three-dimensional item - which includes a cylinder - is sliced perpendicular to some special axis at a factor.
Cut banks are caused by the moving water of the river sporting away the earth. A factor bar then again is placed on the interior of a bend in a river (meander). Because the river curves around the bend within the river, the water slows down and sediment is dropped to the river bed.

The correct answer is - To help schools across Georgia integrate peacefully.
The Sibley Commission in 1960 in Georgia, had the purpose to help the schools in the state to integrate peacefully and without any problems.
This commission put an ultimatum to the Georgia governor that either the schools will integrate and stop the segregation, or all the schools will be forbidden to work.
The officials of Georgia had to accept this as they could not afford all the schools to be closed. Finally, Georgia started integrating the children of all ethnic and racial groups in the schools, thus putting the racism aside.
