Prieglius
The Pregolya or Pregola (; ; ; ) is a river in the Russian Kaliningrad Oblast exclave. Name A possible ancient name by Ptolemy of the Pregolya River is Chronos (from Germanic *''hrauna'', "stony"), although other theories identify Chronos as a much larger river, the Nemunas. The oldest recorded names of the river are ''Prigora'' (1302), ''Pregor'' (1359), ''Pregoll, Pregel'' (1331), ''Pregill'' (1460). Georg Gerullis connected the name with Lithuanian ''prãgaras'', ''pragorė̃'' ("abyss") and the Lithuanian verb ''gérti'' ("drink"). Vytautas Mažiulis instead derived it from ''spragė́ti'' or ''sprógti'' ("burst") and the suffix -''ara'' ("river"). Overview It starts as a confluence of the Instruch and the Angrapa and drains into the Baltic Sea through the Vistula Lagoon. Its length under the name of Pregolya is 123 km, 292 km including the Angrapa. The basin has an area of 15,500 km2. The average flow is 90 m3/s. Euler's Seven Bridges of Königsberg pro ...

Gvardeysk
Gvardeysk ( rus, Гвардейск, p=ɡvɐrˈdʲejsk, a=Ru-Гвардейск.oga; known prior to 1946 by its German name Tapiau ; ; ), is a town and the administrative center of Gvardeysky District in Kaliningrad Oblast, Russia, located on the right bank of the Pregolya River east of Kaliningrad. Population figures: It is located within the historic region of Sambia. History Peter of Dusburg wrote of a settlement known as Tapiow, first documented in 1254, and the neighboring fort ''Surgurbi'' built by 1265.Oesterley, p. 676 The Old Prussian names were derived from the words , , , , meaning 'warm', and , meaning 'around the mountain'. During the 13th century Prussian Crusade, the area was conquered by the Teutonic Knights. To protect Samland from the Nadruvians and Scalvians, the crusaders built a wooden fort between the Deime and Pregel Rivers in 1283–1290. This was replaced by Tapiau Castle, a stone Ordensburg, in 1351. The settlement gradually became know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rivers Of Russia
Russia can be divided into a European and an Asian part. The dividing line is generally considered to be the Ural Mountains. The European part is drained into the Arctic Ocean, Baltic Sea, Black Sea, and Caspian Sea. The Asian part is drained into the Arctic Ocean and the Pacific Ocean. Notable rivers of Russia in Europe are the Volga (which is the longest river in Europe), Pechora, Don, Kama, Oka and the Northern Dvina, while several other rivers originate in Russia but flow into other countries, such as the Dnieper (flowing through Russia, then Belarus and Ukraine and into the Black Sea) and the Western Dvina (flowing through Russia, then Belarus and Latvia into the Baltic Sea). In Asia, important rivers are the Ob, the Irtysh, the Yenisei, the Angara, the Lena, the Amur, the Yana, the Indigirka, and the Kolyma. In the list below, the rivers are grouped by the seas or oceans into which they flow. Rivers that flow into other rivers are ordered by the proximit ...

Łyna (river)
The Łyna (; ; ; - ''Lava''), is a river that begins in northern Poland's Warmian-Masurian Voivodeship and ends in Russia's Kaliningrad Oblast. The Łyna is a tributary of the Pregolya River, and has a total length of 264 km (207 km in Poland and 57 km in Russia) and a basin area of 7,126 km² (5,298 km² in Poland). It is connected to Lake Mamry by the 18th-century Masurian Canal. The river's source is located near the village of Łyna in Masuria, Poland. It then flows through the regions of Warmia, Bartia and Nadrovia. History In historical terms, the river fell within the area of the medieval Monastic state of the Teutonic Knights established in the 13th century. In 1454, the adjacent territory was incorporated by King Casimir IV Jagiellon to the Kingdom of Poland upon the request of the anti-Teutonic Prussian Confederation. It was confirmed as part of Poland after the subsequent Thirteen Years' War, the longest of all Polish–Teutonic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pissa (river)
The Pissa () is a river in the Kaliningrad Oblast in Russia near Chernyakhovsk. Etymology The Pissa, Inster and Angerapp (Angrapa) are tributaries to the Pregolya, Pregel river. These names, of Old Prussian origin, were used by Germans of East Prussia until 1945. According to an anecdote, the inhabitants of Gumbinnen were embarrassed by the name (sounding similar to the vulgar word ''Pisse'', cognate to English "piss") and asked King Friedrich Wilhelm IV for a name change. He is said to have replied ''"Approved. Recommend Urinoco"'' - a toilet humour, toilet pun on Orinoco.Gordon A.

Znamensk, Kaliningrad Oblast
Znamensk (; ; ; ) is a types of inhabited localities in Russia, rural locality (a settlement) in Gvardeysky District of Kaliningrad Oblast, Russia, located on the right bank of the Pregolya River at its confluence with the Łyna River, Lava River east of Kaliningrad. Population figures: History The site of today's Znamensk was originally an Old Prussians, Old Prussian fort, with a settlement named ''Velowe'' nearby. The site featured an unusually large oak tree, considered sacred by the local Prussians. It survived at least until 1595, when it was mentioned by Caspar Hennenberger. Around 1255, the locality was fortified, but the castle was surrendered to the Teutonic Knights by its mayor, Tirslo. The Teutons continued to use the castle and began to colonize the region with ethnic Germans, Germans, giving the settlement the name ''Wehlau''. It received its civic charter in 1335 and in 1339 and became a centre for horse stables and horse trade. Until the late 19th century, the t ...

Seven Bridges Of Königsberg
The Seven Bridges of Königsberg is a historically notable problem in mathematics. Its negative resolution by Leonhard Euler, in 1736, laid the foundations of graph theory and prefigured the idea of topology. The city of Königsberg in Prussia (now Kaliningrad, Russia) was set on both sides of the Pregel River, and included two large islands— Kneiphof and Lomse—which were connected to each other, and to the two mainland portions of the city, by seven bridges. The problem was to devise a walk through the city that would cross each of those bridges once and only once. By way of specifying the logical task unambiguously, solutions involving either # reaching an island or mainland bank other than via one of the bridges, or # accessing any bridge without crossing to its other end are explicitly unacceptable. Euler proved that the problem has no solution. The difficulty he faced was the development of a suitable technique of analysis, and of subsequent tests that established ...

Confluence
In geography, a confluence (also ''conflux'') occurs where two or more watercourses join to form a single channel (geography), channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the river source, source of a river of a new name (such as the confluence of the Monongahela River, Monongahela and Allegheny River, Allegheny rivers, forming the Ohio River); or where two separated channels of a river (forming a river island) rejoin downstream from their point of separation. Scientific study Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern [downstream o ...
