Answers
a)The Aswan Dam, or more specifically since the 1960s, the Aswan High Dam, is an embankment dam built across the Nile in Aswan, Egypt, between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream.
Location: Aswan, Egypt
Maximum water depth: 180 m (590 ft)
Spillway capacity: 11,000 m3/s (390,000 cu ft/s)
Total capacity: 132 km3 (107,000,000 acre⋅ft)
b)Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt
c)Damodar River (Pron: /ˈdæmoˌdaː/) is a river flowing across the Indian states of Jharkhand and West Bengal. Rich in mineral resources, the valley is home to large-scale mining and industrial activity. Earlier known as the Sorrow of Bengal[2] because of its ravaging floods in the plains of West Bengal, the Damodar and its tributaries have been somewhat tamed with the construction of several dams. It is the most polluted river of India (by 2003).[3]
d)Hirakud Dam is built across the Mahanadi River, about 15 kilometres (9.3 mi) from Sambalpur in the state of Odisha in India. Behind the dam extends a lake, Hirakud Reservoir, 55 km (34 mi) long. It is one of the first major multipurpose river valley projects started after India's independence.
1.Multipurpose River Valley Projects in India
Multipurpose river valley projects are basically designed for the development of irrigation for agriculture and electricity through the construction of dams. Initially, dams were built only for storing rain water to prevent flooding but now it became multipurpose. Here, we are giving the list of important river-valley projects in India which will help the students for quick revision.
