Ritom Lake
__NOTOC__ Lago Ritom is a lake in the Piora valley, Ticino, Switzerland. The natural lake is used as a reservoir by the Swiss Federal Railways (SBB-CFF-FFS) to generate hydro-electric power for the Gotthard line. The first dam was built in 1918 and, in 1950, its height was increased by 23 m. Overview The lake's surface area is 1.49 km² at an elevation of 1850 m. With Lake Cadagno and Lago di Tom, it is one of the main lakes in the Piora valley. Before being used as a reservoir, Lake Ritom was a meromictic lake similar to the nearby Lake Cadagno. Transport The lake can be reached by funicular from Piotta 786 m below. The track with a length of 1,369 m has a maximum inclination of 87.8%, the highest in Europe after the Gelmerbahn funicular (106%).

Meromictic Lake
A meromictic lake is a lake which has layers of water that do not intermix. In ordinary, holomictic lakes, at least once each year, there is a physical mixing of the surface and the deep waters. The term ''meromictic'' was coined by the Austrian Ingo Findenegg in 1935, apparently based on the older word ''holomictic''. The concepts and terminology used in describing meromictic lakes were essentially complete following some additions by G. Evelyn Hutchinson in 1937. Characteristics Most lakes are ''holomictic'': at least once per year, the surface and the deep waters mix. In monomictic lakes, the mixing occurs once per year; in dimictic lakes, it occurs twice a year (typically spring and autumn), and in polymictic lakes, the mixing occurs several times a year. In meromictic lakes, the layers of water can remain unmixed for years, decades, or centuries. Meromictic lakes can usually be divided into three sections or layers. The bottom layer is the ''monimolimnion''; the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Mountain Lakes Of Switzerland
This is a list of high-altitude lakes of Switzerland. It includes all significant lakes located either entirely or partly in Switzerland, both natural and artificial, with an area of at least 4 ha (9.9 acres) and a location at over above sea level. This altitude approximately corresponds to the transition between the foothill zone and the montane zone in both the Alps and the Jura Mountains, the two mountainous areas of Switzerland. Lakes can be found up to elevations of almost , the climatic snow line in the Alps.

Gelmerbahn Funicular
The Gelmer Funicular is a cable railway in the canton of Bern, Switzerland. It links a lower terminus at Handegg, in the Haslital (the valley of the upper Aar (river), Aar River), with an upper terminus at the Gelmersee lake, above. With an incline of 106% (or 47°), Gelmerbahn was the steepest funicular in Switzerland and Europe, until the opening of the new Stoos Funicular in 2017. The Handegg terminus of the line is close to the road over the Grimsel Pass. It is accessible by car and by an infrequent PostBus Switzerland, PostBus service. It is technically not a funicular, which has two cars that counterbalance each other, but is propelled by a winch. History The funicular was originally built to facilitate the construction of the Gelmersee, a reservoir, constructed in 1926 in order to exploit the hydroelectric resources of the area and was not opened for public use until 2001. The line is owned and operated by Kraftwerke Oberhasli AG (KWO) which owns the power station. Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade (slope)
The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal plane, horizontal or its tangent. It is a special case of the slope, where zero indicates horizontal plane, horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, bank (geography), stream and river banks, and stream bed, beds are often described as grades, but typically the word "grade" is used for human-made surfaces such as roads, landscape grading, roof pitches, rail tracks, railroads, aqueduct (watercourse), aqueducts, and pedestrian or bicycle routes. The grade may refer to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piotta, Switzerland
Piotta is a village in the Quinto, Ticino, municipality of Quinto in the Swiss canton of Ticino.

Funicular
A funicular ( ) is a type of cable railway system that connects points along a railway track laid on a steep grade (slope), slope. The system is characterized by two counterbalanced carriages (also called cars or trains) permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. The term ''funicular'' derives from the Latin word , the diminutive of , meaning 'rope'. Operation In a funicular, both cars are permanently connected to the opposite ends of the same cable, known as a ''haul rope''; this haul rope runs through a system of pulleys at the upper end of the line. If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ticino
Ticino ( ), sometimes Tessin (), officially the Republic and Canton of Ticino or less formally the Canton of Ticino, is one of the Canton of Switzerland, 26 cantons forming the Switzerland, Swiss Confederation. It is composed of eight districts and its capital city is Bellinzona. It is also traditionally divided into the Sopraceneri and the Sottoceneri, respectively north and south of Monte Ceneri. Ticino is the southernmost canton of Switzerland. It is one of the three large southern Alps, Alpine cantons, along with Valais and the Grisons. However, unlike all other cantons, it lies almost entirely south of the Alps and has no natural access to the Swiss Plateau. Through the main crest of the Saint-Gotthard Massif, Gotthard and adjacent mountain ranges, it borders the canton of Valais to the northwest, the canton of Canton of Uri, Uri to the north and the canton of Grisons to the northeast; the latter canton being also the only one to share some borders with Ticino at the level ...

Lake Cadagno
__NOTOC__ Lake Cadagno (Italian: ''Lago di Cadagno'') is a meromictic lake in the Piora valley (canton of Ticino), Switzerland. As one of a few meromictic lakes in Europe, it is the object of numerous scientific studies. The Piora valley - located in the Saint-Gotthard Massif (central Swiss Alps) in the Southern part of Switzerland near Airolo at an altitude of 1921 m above sea level - is a landlocked alpine valley whose scientific value has been recognized for more than two centuries. In the past, the lake was used as a reservoir. Lake Cadagno is a rare example of crenogenic meromixis. Its waters show a permanent stratification due to a natural geological phenomenon. The lower abounds with dissolved mineral salts (sulphate, magnesium, calcium, carbonate) originating from sublacustrine springs, whereas the separate upper layer is permanently oxygenated. Anaerobic phototrophic bacteria – among them ''Chromatium okenii''—thrive between the two layers where they find the ideal cond ...
