Lake Ülemiste
Lake Ülemiste ( et, Ülemiste järv) is the largest of the lakes surrounding Tallinn, Estonia. Ülemiste is the main part of the Tallinn water supply system, which supplies the city with most of its drinking water. The lake is fed mostly by Kurna stream and the Pirita River, through the Vaskjala–Ülemiste canal. Lennart Meri Tallinn Airport is located on the eastern shore of the lake and aircraft regularly take off and land over the lake. The airport maintains the necessary equipment ready to salvage in a short time any aircraft that crashes into the lake, as required by International Civil Aviation Organization regulations. The Tallinn Water Company, AS Tallinna Vesi, has a treatment plant on the north shore of the lake which supplies 90% of the water to the city. The remaining 10% comes from ground water wells, which are maintained as a backup in case the lake becomes contaminated. On 18 March 2010, a DHL Antonov An-26 aircraft made an emergency landing on the ice of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tallinn Bay
Tallinn Bay ( et, Tallinna laht) is a bay in Estonia on the southern coast of the Gulf of Finland. The Estonian capital city Tallinn is located on the southern coast of the bay. Tallinn Bay itself is divided into several parts: Tallinn Roadstead (), Kopli Bay, Kakumäe Bay and Paljassaare Bay. The islands Naissaar and Aegna border the bay in the north, the Viimsi Peninsula to the east. The shore waters are shallow but deep rapidly. Tallinn Bay has a steep slope, which allows for good water exchange with the waters of the Gulf of Finland. Tallinn Bay is one of the deepest bays in Estonia, max depth is about 100 m.Autorite kollektiiv. 1996. ''Mereleksikon''.

Gulf Of Finland
The Gulf of Finland ( fi, Suomenlahti; et, Soome laht; rus, Фи́нский зали́в, r=Finskiy zaliv, p=ˈfʲinskʲɪj zɐˈlʲif; sv, Finska viken) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in Russia to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. Proposals for a tunnel through the gulf have been made. Geography The gulf has an area of . The length (from the Hanko Peninsula to Saint Petersburg) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Watermill
A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, wire drawing mills. One major way to classify watermills is by wheel orientation (vertical or horizontal), one powered by a vertical waterwheel through a gear mechanism, and the other equipped with a horizontal waterwheel without such a mechanism. The former type can be further divided, depending on where the water hits the wheel paddles, into undershot, overshot, breastshot and pitchback (backshot or reverse shot) waterwheel mills. Another way to classify water mills is by an essential trait about their location: tide mills ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sewage
Sewage (or domestic sewage, domestic wastewater, municipal wastewater) is a type of wastewater that is produced by a community of people. It is typically transported through a sewer system. Sewage consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in the locality. Sub-types of sewage are greywater (from sinks, bathtubs, showers, dishwashers, and clothes washers) and blackwater (the water used to flush toilets, combined with the human waste that it flushes away). Sewage also contains soaps and detergents. Food waste may be present from dishwashing, and food quantities may be increased where garbage disposal units are used. In regions where toilet paper is used rather than bidets, that paper is also added to the sewage. Sewage contains macro-pollutants and micro-pollutants, and may also incorporate some municipal solid waste and pollutants from industrial wastewater. Sewage usually travels from a building's ...

Former Rivers
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the adv ...
