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 ...

It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt (modern-day Bilecik Province) by the Turkoman tribal leader Osman I. After 1354, the Ottomans crossed into Europe and, with the conquest of the Balkans, the Ottoman beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the conquest of Constantinople in 1453 by Mehmed the Conqueror.

Sultan
Sultan (; ar, سلطان ', ) is a position with several historical meanings. Originally, it was an Arabic abstract noun meaning "strength", "authority", "rulership", derived from the verbal noun ', meaning "authority" or "power". Later, it came to be used as the title of certain rulers who claimed almost full sovereignty (i.e., not having dependence on any higher ruler) without claiming the overall caliphate, or to refer to a powerful governor of a province within the caliphate. The adjectival form of the word is "sultanic", and the state and territories ruled by a sultan, as well as his office, are referred to as a sultanate ( '. The term is distinct from king ( '), despite both referring to a sovereign ruler. The use of "sultan" is restricted to Muslim countries, where the title carries religious significance, contrasting the more secular ''king'', which is used in both Muslim and non-Muslim countries.

Mahmud II
Mahmud II ( ota, محمود ثانى, Maḥmûd-u s̠ânî, tr, II. Mahmud; 20 July 1785 – 1 July 1839) was the 30th Sultan of the Ottoman Empire from 1808 until his death in 1839. His reign is recognized for the extensive administrative, military, and fiscal reforms he instituted, which culminated in the Decree of Tanzimat ("reorganization") that was carried out by his sons Abdulmejid I and Abdülaziz. Often described as "Peter the Great of Turkey", Mahmud's reforms included the 1826 abolition of the conservative Janissary corps, which removed a major obstacle to his and his successors' reforms in the Empire. The reforms he instituted were characterized by political and social changes, which would eventually lead to the birth of the modern Turkish Republic. Notwithstanding his domestic reforms, Mahmud's reign was also marked by nationalist uprisings in Ottoman-ruled Serbia and Greece, leading to a loss of territory for the Empire following the emergence of an independ ...

Belgrad Forest
Belgrad Forest ( tr, Belgrad Ormanı) is a mixed deciduous forest lying adjacent to Istanbul, Turkey. It is named after the village next to the forest, settled by thousands of Serbs who were deported to the capital Constantinople from the city of Belgrade in 1521, when it fell to the Ottomans. Geographically, the forest is located at the easternmost point of the Thracian Peninsula. Forest terrain is divided between Sarıyer and Eyüp districts. Several historical reservoirs lie within the forest. History The Thracian village of Belgrad (from which the forest takes its name) was named after the thousands of Serbs that Suleiman the Magnificent had transferred to Thrace after the 1521 Siege of Belgrade. Size and composition of the forest With a region around 5,500 hectares of forest it houses many plant, bird and animal species. The most common tree in the forest is sessile oak (''Quercus petraea''). Belgrad Forest is under protection and is one of the most visited recreational a ...

Thalweg
In geography and fluvial geomorphology, a thalweg or talweg () is the line of lowest elevation within a valley or watercourse. Under international law, a thalweg is the middle of the primary navigable channel of a waterway that defines the boundary line between states. Also under international law, thalwegs can acquire special significance because disputed river borders are often deemed to run along the river's thalweg. Etymology The word ''thalweg'' is of 19th-century German origin. The German word (modern spelling ) is a compound noun that is built from the German elements (since Duden's orthography reform of 1901 written ) meaning ''valley'' (cognate with ''dale'' in English), and , meaning ''way.'' It literally means "valley way" and is used, with its modern spelling , in daily German to describe a path or road that follows the bottom of a valley, or in geography with the more technical meaning also adopted by English.
