Tase Dam
is a multipurpose dam located on the Sarugaishi River in the former town of Tōwa which is now a part of the city of Hanamaki in Iwate Prefecture, in the Tohoku region of northern Japan. Completed in 1954, it is managed by the Tohoku Regional Development Bureau of the Ministry of Land, Infrastructure and Transport. Located on the Sarugaishi River, a branch of the Kitakami River, it is the first of the dams completed as part of the Kitakami Area Comprehensive Development Plan (KVA). The dam creates , a popular sightseeing spot. History The lower reaches of the Kitakami River are subject to flooding, especially near its dual mouths at the city of Ichinoseki, Iwate, and plans to increase the river width were impractical due to urbanisation of the area. The Home Ministry, together with Tokyo Imperial University drafted a flood control plan in 1926, which was upgraded in 1938 when implementation began. The plan called for the construction of five large dams on the main stream of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarugaishi River
The is a river in Iwate Prefecture, Japan. The Sarugaishi River rises in the Kitakami Mountains just south of Mt. Yakushi in Tōno and empties into the Kitakami River in Hanamaki. The Tase Dam is on the Sarugaishi River, in eastern Hanamaki in the former town of Tōwa. This dam was completed in 1953. There is a legend that the entire floodplain of the river in Tōno was once a large lake dammed by the hills in Miyamori. Course left, The Sarugaishi and Hayase Rivers From its headwaters in Hayachine Quasi-National Park near Mt. Yakushi the Sarugaishi River flows directly south through the Tsukimoushi section of the city of Tōno. In Matsuzaki the river makes a slow and gentle bend to the west and flows west-southwest through Ayaori. In Miyamori the Sarugaishi encounters large hills that force the river into a steep and winding canyon which continues into Hanamaki where the Tase Dam impounds the water. Lake Tase bends back to the north with the outflow of the dam directed eastw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dams Completed In 1954
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tennessee Valley Authority
The Tennessee Valley Authority (TVA) is a federally owned electric utility corporation in the United States. TVA's service area covers all of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small areas of Georgia, North Carolina, and Virginia. While owned by the federal government, TVA receives no taxpayer funding and operates similarly to a private for-profit company. It is headquartered in Knoxville, Tennessee, and is the sixth largest power supplier and largest public utility in the country. The TVA was created by Congress in 1933 as part of President Franklin D. Roosevelt's New Deal. Its initial purpose was to provide navigation, flood control, electricity generation, fertilizer manufacturing, regional planning, and economic development to the Tennessee Valley, a region that had suffered from lack of infrastructure and poverty during the Great Depression, relative to the rest of the nation. TVA was envisioned both as a power supplier and a regional economi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shigeru Yoshida
(22 September 1878 – 20 October 1967) was a Japanese diplomat and politician who served as prime minister of Japan from 1946 to 1947 and from 1948 to 1954. Yoshida was one of the longest-serving Japanese prime ministers, and is the third-longest serving prime minister of post-occupation Japan. Early life and education Yoshida was born on 22 September 1878, in Kanda-Surugadai, Tokyo, the fifth son of political activist and former samurai Tsuna Takeuchi. Tsuna was a devout supporter of Itagaki Taisuke and would later serve in the first National Diet in 1890. Yoshida's biological mother's identity is not known. Shortly before his birth, his biological father was arrested for anti-government conspiracy, and his mother gave birth to him at the house of Kenzō Yoshida, a friend of his father. As young samurai, Tsuna and Kenzō had made a name amidst the decades of unrest around the time of Meiji Restoration. In August 1881, Yoshida was adopted by Kenzō Yoshida and his wife Kotoko ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather (climate cha ...

Kitakami River
The is the fourth largest river in Japan and the largest in the Tōhoku region. It is long and drains an area of . page 793 It flows through mostly rural areas of Iwate and Miyagi Prefectures. The source of the river is the Mount Nanashiruge in northern Iwate, from which it flows to the south between the Kitakami Mountains and the Ōu Mountains. The river is unusual in that it has two mouths, one flowing south into Ishinomaki Bay and the other flowing east into the Pacific Ocean, both in Ishinomaki City. The Kitakami river was an important transportation route during the Edo period and before the building of railways in the early Meiji period. Numerous dams have been constructed on the river and its tributaries from the Taishō and Shōwa periods for hydroelectric power generation, flood control and irrigation. However, another unusual feature is that there are no dams from its mouth to the Shijūshida Dam north of Morioka. This allows for a spectacular salmon run every fal ...

Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...
