Bibai Dam
The is a dam in Bibai, Hokkaidō, Japan. The Bibai Dam is constructed along the Mikawa River and is part of the Ishikari River water system. Bibai Dam was Hokkaido's first multipurpose auxiliary dam project. It is a 35.5m tall concrete Gravity dam. The dam was named after the Bibai Lake in 1987 by public designation. History In August 1966, a flood occurred in the city of Bibai, Hokkaido which led to the deaths of 2 and the tremendous damage to the city. This led to the small and medium rivers and lakes improvement project review. A study of the revision of the high water flow rate and flood control plan conclusion that a flood dam plan should be considered. Due to the sharp decline in coal demand, the main industry in the region, the industrial structure was forced to change and the industrial area was moved from Chashinai Station to Naie, Hokkaido in order to attract more business to the industrial park. Due to urbanization, it became necessary to secure a new wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hokkaidō
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''. Nussbaum, Louis-Frédéric. (2005). "Hokkaidō" in Although there were Japanese settlers who ruled the southern tip of the island since the 16th century, Hokkaido was considered foreign territory that was inhabited by the indigenous people of the island, known as the Ainu people.

Hectares
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is ...

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 ...

Babai River
The Babai River ( ne, बबई नदी) originates in and completely drains Inner Terai Dang Valley of Mid-Western Nepal. Dang is an oval valley between the Mahabharat Range and Siwalik Hills in its eponymous district. Dang was anciently home to indigenous Tharu people and came to be ruled from India by the House of Tulsipur who also counted as one of the Baise Rajya ( ne, बाइसे राज्य)—a confederation of 22 petty kingdoms in the Karnali (Ghagra) region. About 1760 AD all these kingdoms were annexed by the Shah Dynasty during the unification of Nepal, except Tulsipur lands south of the Siwalik Hills were not taken. Since Dang Valley was somewhat higher, cooler, better-drained and therefore less malarial than most of the country's Inner Terai, it was settled to some extent by Shah and Rana courtiers and other Paharis long before DDT was introduced to control the disease-bearing ''Anopheles'' mosquito. Exiting Dang Valley and its district, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crest Gate
Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm surge system. Since most of these devices operate by controlling the water surface elevation being stored or routed, they are also known as crest gates. In the case of flood bypass systems, floodgates sometimes are also used to lower the water levels in a main river or canal channels by allowing more water to flow into a flood bypass or detention basin when the main river or canal is approaching a flood stage. Types Valves Valves used in floodgate applications have a variety of design requirements and are usually located at the base of dams. Often, the most important requirement (besides regulating flow) is energy dissipation. Since water is very he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
