Kuji River (Iwate)
is a river in Kuji, Iwate of Japan. It rises at Mount Myojindake located in Kitakami Mountains, and flows into the Pacific Ocean at Kuji City. It is in length, and is designated as a Class B river. The urban area of Kuji City is situated on the alluvial plain of the river. is located along the upper reach of the river. It has a water spring named Furosen (不老泉, literally "ageless spring"), which is known for one of the valuable water springs in Iwate. Water from the spring was initially utilized for placer gold mining in Meiji Era. Later in the Taisho Era it was named after a legend, in which one had become immortal after drinking the water. The valley is a part of Kuji-Hiraniwa Prefectural Natural Park. Kuji Region used to contain characteristic Tatara furnaces, in which a water wheel was utilized to supply the air to the furnace, while in many other regions of the country man-power was utilized. Today some parts of the furnaces remain along a tributary river of Kuji ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alluvial Plain
An alluvial plain is a largely flat landform created by the deposition of sediment over a long period of time by one or more rivers coming from highland regions, from which alluvial soil forms. A floodplain is part of the process, being the smaller area over which the rivers flood at a particular period of time, whereas the alluvial plain is the larger area representing the region over which the floodplains have shifted over geological time. As the highlands erode due to weathering and water flow, the sediment from the hills is transported to the lower plain. Various creeks will carry the water further to a river, lake, bay, or ocean. As the sediments are deposited during flood conditions in the floodplain of a creek, the elevation of the floodplain will be raised. As this reduces the channel floodwater capacity, the creek will, over time, seek new, lower paths, forming a meander (a curving sinuous path). The leftover higher locations, typically natural levees at the margins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Water Wheel
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth. Some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a water wheel is called a mill race. The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace. Waterwheels were used for various purposes from ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tatara (furnace)
The is the traditional Japanese furnace used for smelting iron and steel. The word later also came to mean the entire building housing the furnace. The traditional steel in Japan comes from ironsand processed in a special way, called tatara system.https://www.jsme.or.jp/tsd/ICBTT/conference02/TatsuoINOUE.html "Science of Tatara and Japanese Sword - Traditional Technology viewed from Modern Science" by Tatsuo INOUE Iron ore was used in the first steel manufacturing in Japan. Tatara steelmaking process using ironsand was conducted in the Kibi Province, which later became the base of the Bizen school of swordsmithing, around the middle of the sixth century, and steelmaking using ironsand is thought to have spread from Kibi to various places in Japan. In western Japan, a low box-shaped furnace different from the Chinese and Korean style was used to refine iron, and in eastern Japan, both a low box-shaped furnace and a vertical furnace unique to Japan were used.

Meiji Era
The is an era of Japanese history that extended from October 23, 1868 to July 30, 1912. The Meiji era was the first half of the Empire of Japan, when the Japanese people moved from being an isolated feudal society at risk of colonization by Western powers to the new paradigm of a modern, industrialized nation state and emergent great power, influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas. As a result of such wholesale adoption of radically different ideas, the changes to Japan were profound, and affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded to the reign of Emperor Meiji. It was preceded by the Keiō era and was succeeded by the Taishō era, upon the accession of Emperor Taishō. The rapid modernization during the Meiji era was not without its opponents, as the rapid changes to society caused many disaffected traditionalists from the former samurai cl ...

Placer Mining
Placer mining () is the mining of stream bed (Alluvium, alluvial) deposits for minerals. This may be done by open-pit mining, open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in Alluvium, alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total deposit. Since gems and heavy metals like gold are considerably denser than sand, they tend to accumulate at the base of placer deposits. Placer deposits can be as young as a few years old, such as the Canadian Queen Charlotte beach gold placer deposits, or billions of years old like the Elliot Lake uranium paleoplacer within the Huronian Supergroup i ...

Class A River
Rivers in Japan are classified according to criteria set by the , which was introduced in 1967. Rivers are designated as Class A or Class B river systems by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT). Class A rivers is a designation applied to rivers and waterways deemed to be important to the economy of the nation as a whole, as well as those deemed important to the conservation of nature within Japan. There are currently 109 rivers with this designation. List of Class A river systems The number of dams only includes existing and unestablished dams that meet the criteria ( or more in bank height) of the River Law. The management entity is irrelevant. The number in parentheses is the number of dams on the main river, excluding tributaries. The number of dams does not always exceed the number of hydroelectric plants because plants with intake weirs less than high are not considered dams.
