Gandō Dam
is a dam on the Tandogawa River, a branch of the Kitakami River in Morioka, Iwate Prefecture, Japan, completed in 1960. History The need for storage reservoirs in the Kitakami River valley for irrigation purposes was recognized by the Meiji government at the start of the 20th century, due to repeated crop failures and conflicts between various communities over water rights. The river also suffered from severe environmental problems with acidic runoff from upstream mining operations. Plans for a series of dams was initiated in 1941 by the Ministry of Agriculture and Forestry, but all work was halted during World War II. The plan was revived after the war, and the Gandō Dam was the second to be completed after the Sannōkai Dam. Design The Gandō Dam was constructed to provide irrigation water, and also to supply the 41,000 KW Gandō No.1 Hydroelectric Plant and 8,300 KW Gandō No.2 Power Plants. The design of the dam is that of a sloped wall rockfill dam. The dam was completed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

They did have a number of things in common; according to Andrew Gordon, “It was precisely their intermediate status and their insecure salaried position, coupled with their sense of frustrated ambition and entitlement to rule, that account for the revolutionary energy of the Meiji insurgents and their far-reaching program of reform”. most were in their mid-40s, and most were from the four '' tozama'' domains of western Japan (Chōshū, Satsuma, Tosa and Hizen).

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] |

Rockfill Dam
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] |

Carp
Carp are various species of oily freshwater fish from the family Cyprinidae, a very large group of fish native to Europe and Asia. While carp is consumed in many parts of the world, they are generally considered an invasive species in parts of Africa, Australia and most of the United States. Biology The cypriniformes (family Cyprinidae) are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair of ribs is in contact with the extension of the labyrinth and the posterior with the swim bladder. The function is poorly understood, but this structure is presumed to take part in the transmission of vibrations from the swim bl ...

Smelt (fish)
Smelts are a family of small fish, the Osmeridae, found in the North Atlantic and North Pacific Oceans, as well as rivers, streams and lakes in Europe, North America and Northeast Asia. They are also known as freshwater smelts or typical smelts to distinguish them from the related Argentinidae (herring smelts or argentines), Bathylagidae (deep-sea smelts), and Retropinnidae (Australian and New Zealand smelts). Some smelt species are common in the North American Great Lakes, and in the lakes and seas of the northern part of Europe, where they run in large Shoaling and schooling, schools along the saltwater coastline during spring migration to their spawning streams. In some western parts of the United States, smelt populations have greatly declined in recent decades, leading to their protection under the Endangered Species Act. The Delta smelt (''Hypomesus transpacificus'') found in the Sacramento Delta of California, and the eulachon (''Thaleichthys pacificus'') found in the Nort ...
