Aswan Dam Abdel Nasser. The Free Officers were convinced that the Nile Waters had to be stored in Egypt for political reasons, and within two months, the plan of Daninos was accepted. Initially, both the United States and the USSR were interested in helping the development of the dam, but this movement happened in the midst of the Cold War, as well as of growing intra-Arab rivalries. In 1955, Nasser was trying to portray himself as the leader of Arab nationalism, in opposition to the traditional monarchies, especially the Hashemite Kingdom of Iraq following its signing of the 1955 Baghdad Pact. At
Hydropower policy in the United States of 90% efficiency. More importantly, Francis's mathematical and graphical calculation methods advanced turbine design and engineering and allowed confident design of high efficiency turbines to exactly match a site's flow conditions. In the 1870s and deriving from uses in the mining industry, the high efficiency Pelton wheel impulse turbine was developed to use hydropower under very different flow and pressure conditions. Advances in dam design also progressed, with the completion of Old Aswan Dam being considered a milestone of engineering over nature. At the time of its construction, nothing of such scale had ever been attempted: it also became one
