supports: Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf. The Swiss Plateau or Central Plateau  constitutes one of the three major landscapes in Switzerland alongside the Jura Mountains and the Swiss Alps. It covers about 30% of the Swiss surface. It comprises the regions between the Jura and the Alps, partly flat but mostly hilly, and lies at an average height between 400 and 700 m AMSL. It is by far the most densely populated region of Switzerland, and the most important with respect to economy and transportation. France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux. Etymology is the study of the history of words, their origins, and how their form and meaning have changed over time. By extension, the term "the etymology (of a word)" means the origin of the particular word. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope). They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses. Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state. Ticino , formally the Republic and Canton of Ticino (;  ; see also in other languages) is the southernmost canton of Switzerland. Ticino borders the Canton of Uri to the north, Valais to the west (through the Novena Pass), Graubünden to the northeast, Italy's regions of Piedmont and Lombardy to the south and it surrounds the small Italian exclave of Campione d'Italia. Geneva (, , , ) is the second most populous city in Switzerland (after Zürich) and is the most populous city of Romandy, the French-speaking part of Switzerland. Situated where the Rhône exits Lake Geneva, it is the capital of the Republic and Canton of Geneva. The Alps are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across eight Alpine countries: Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the FrenchItalian border, and at is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres (just over 13,000 feet). The League of God's House (German: "Gotteshausbund", Italian: "Lega Caddea") was formed in what is now Switzerland on January 29, 1367 to resist the rising power of the Bishopric of Chur and the House of Habsburg. The League allied with the Grey League and the League of the Ten Jurisdictions in 1471 to form the Three Leagues. The League of God's House, together with the two other Leagues, was allied with the Old Swiss Confederacy throughout the 15th and 16th centuries. After the Napoleonic wars the League of God's House became a part of the Swiss canton of Graubünden. The League of the Ten Jurisdictions was the last of the Three Leagues founded during the Middle Ages in what is now Canton Graubünden of Switzerland. The League was created in the County of Toggenburg after the counts of Toggenburg died out. The League initially existed to resist the power of the House of Habsburg, and quickly allied with the Grey League and the League of God's House. In 1524 the three leagues joined together to become the Free State of the Three Leagues, which existed until the Napoleonic dissolution of the Free State. A landlocked state or landlocked country is a sovereign state entirely enclosed by land, or whose only coastlines lie on closed seas. There are currently 48 such countries, including four partially recognised states. Only two, Bolivia and Paraguay in South America, lie outside Afro-Eurasia (the Old World). A dam is a barrier that impounds 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 water or for storage of 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 Grey League (, or ), sometimes called "Oberbund", formed in 1395 in the "Vorderrhein" and "Hinterrhein" valleys, Raetia. The name Grey League is derived from the homespun grey clothes worn by the people. The league became part of the canton of Graubünden. The Grey League allied itself to the two other powers of Raetia in 1471, forming the Three Leagues. It was also an associate and ally of the Swiss Confederation and played a role in the build up to the Thirty Years' War. Lai da Curnera is a reservoir on the river Rein da Curnera in the municipality of Tujetsch, in the Grisons, Switzerland. The reservoir is linked to Lai da Sontga Maria and Lai da Nalps in the neighboring valley. The lake's volume is 41.1 mio m³ and its surface area 0.81 km². A federal republic is a federation of states with a republican form of government. At its core, the literal meaning of the word republic when used to reference a form of government means: "a country that is governed by elected representatives and by an elected leader (such as a president) rather than by a king or queen". Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries. Swiss German (Standard German: "Schweizerdeutsch", , and others) refers to any of the Alemannic dialects spoken in the German-speaking part of Switzerland and in some Alpine communities in Northern Italy bordering Switzerland. Occasionally, the Alemannic dialects spoken in other countries are grouped together with Swiss German, as well, especially the dialects of Liechtenstein and Austrian Vorarlberg, which are closely associated to Switzerland's. Liechtenstein , officially the Principality of Liechtenstein, is a doubly landlocked German-speaking microstate in Central Europe. It is a constitutional monarchy with the rank of principality, headed by the Prince of Liechtenstein. Lai da Sontga Maria (Italian: "Lago di Santa Maria") is a lake, located north of the Lukmanier Pass in Switzerland. It lies almost entirely in the municipality of Medel (canton of Graubünden), a tiny fraction of the south-west part of the lake belonging to the municipalities of Quinto and Blenio (canton of Ticino). The reservoir has a surface area is 1.77 km². The arch dam Santa Maria was completed in 1968. The main road of the Lukmanier Pass runs along the eastern shore of the lake. Lai da Nalps is a reservoir in the municipality of Tujetsch , Grisons , Switzerland . It has a capacity of 45 million m³ and a surface area of 0.91 km² . The reservoir is connected to Lai da Sontga Maria and Lai da Curnera in neighboring valleys . A levee,, dike, dyke, embankment, floodbank or stopbank is an elongated naturally occurring ridge or artificially constructed fill or wall, which regulates water levels. It is usually earthen and often parallel to the course of a river in its floodplain or along low-lying coastlines. Central Europe lies between Eastern Europe and Western Europe. The concept of Central Europe is based on a common historical, social and cultural identity. Central Europe is going through a phase of "strategic awakening", with initiatives such as the CEI, Centrope or V4. While the region's economy shows high disparities with regard to income, all Central European countries are listed by the Human Development Index as very highly developed. Blenio is a municipality of the district of Blenio, in the canton of Ticino, Switzerland. A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams. The city of Bern or Berne (; Bernese German: "Bärn" ) is the de facto capital of Switzerland, referred to by the Swiss as their (e.g. in German) "Bundesstadt," or "federal city". With a population of 141,762 (November 2016), Bern is the fourth most populous city in Switzerland. The Bern agglomeration, which includes 36 municipalities, had a population of 406,900 in 2014. The metropolitan area had a population of 660,000 in 2000. Bern is also the capital of the canton of Bern, the second most populous of Switzerland's cantons. Switzerland, officially the Swiss Confederation, is a federal republic in Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. 
  The country is situated in Western-Central Europe, and is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of . While the Alps occupy the greater part of the territory, the Swiss population of approximately eight million people is concentrated mostly on the plateau, where the largest cities are to be found: among them are the two global cities and economic centres Zürich and Geneva. Grisons (  see also other names) is the largest and easternmost canton of Switzerland. The canton shares borders with the cantons of Ticino, Uri, Glarus and St. Gallen and international borders with Italy, Austria and Liechtenstein. The name Graubünden translates as the "Grey Leagues," referring to the canton's origin in three local alliances, the League of God's House, the Grey League, and the League of the Ten Jurisdictions. Grisons is also home to three of Switzerland's ethnic groups and the subsequent languages of Swiss German, Italian and Romansh are all native to the state. It is the only officially trilingual canton and the only canton where the Romansh language has official status. A reservoir (etymology: from French "réservoir" a "storehouse" ) is a storage space for fluids. These fluids may be water, hydrocarbons or gas. A reservoir usually means an enlarged natural or artificial lake, storage pond or impoundment created using a dam or lock to store water.
  Reservoirs can be created by controlling a stream that drains an existing body of water. They can also be constructed in river valleys using a dam. Alternately, a reservoir can be built by excavating flat ground and/or constructing retaining walls and levees. An arch dam is a solid dam made of concrete that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, compressing and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow gorges or canyons with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas. Tujetsch is a municipality in the district of Surselva in the canton of Graubünden in Switzerland.
