Ciabrus
The Tsibritsa ( bg, Цибрица, ; also transliterated as ''Cibrica'', ''Tzibritza''; la, Ciabrus) is a river in the western Danubian Plain of northern Bulgaria and a right tributary of the Danube. The river originates in the Shiroka Planina ("Wide Mountain") area of the Fore-Balkan Mountains near the Serbian border and flows in a northeast direction diagonally through Montana Province. East of the village of Dolni Tsibar in Valchedram municipality, it flows into the Danube. The Tsibritsa has a length of 91.2 kilometres and a drainage basin of 922 square kilometres. At Ignatovo near the Tsibritsa's mouth its average discharge is 2 cubic metres per second. The river's waters are used for irrigation. The low plateau between the Tsibritsa to the west and the Ogosta to the east is known as Zlatiya and is a fertile agricultural region.

Triballi
The Triballi ( grc, Τριβαλλοί, Triballoí, lat, Triballi) were an ancient people who lived in northern Bulgaria in the region of Roman Oescus up to southeastern Serbia, possibly near the territory of the Morava Valley in the late Iron Age. The Triballi lived between Thracians to the east, Illyrians the west and Celts to the north and were influenced by them. As such in contemporary sources, they are variably described as an independent, Thracian, Illyrian or Celtic tribe. As an existing people, the Triballi are mentioned for the last time by Roman historian Appian (2nd century CE). According to Appian, the Triballi were reduced in numbers through their wars against the Scordisci and fled among the Getae, north of the Danube before they went extinct as a distinct people. History The Triballi ( grc, Τριβαλλοί, Triballoí) are mentioned for the first in history by ancient Greek authors of Classical period: Aristotle and Demosthenes, both of whom lived in the 4th ...

Danube
The Danube ( ; ) is a river that was once a long-standing frontier of the Roman Empire and today connects 10 European countries, running through their territories or being a border. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The largest cities on the river are Vienna, Budapest, Belgrade and Bratislava, all of which are the capitals of their respective countries; the Danube passes through four capital cities, more than any other river in the world. Five more capital cities lie in the Danube's basin: Bucharest, Sofia, Zagreb, Ljubljana and Sarajevo. The fourth-largest city in its basin is Munich, the capital of Bavaria, standing on the Isar River. The Danube is the second-longest river in Europe, after the Volga in Russia. It flows through much of Central and Sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thracians
The Thracians (; grc, Θρᾷκες ''Thrāikes''; la, Thraci) were an Indo-European languages, Indo-European speaking people who inhabited large parts of Eastern Europe, Eastern and Southeast Europe, Southeastern Europe in ancient history.. "The Thracians were an Indo-European people who occupied the area between northern Greece, southern Russia, and north-western Turkey. They shared the same language and culture... There may have been as many as a million Thracians, diveded among up to 40 tribes." Thracians resided mainly in the Balkans (mostly Present (time), modern day Bulgaria, Turkey and Greece) but were also located in Anatolia, Anatolia (Asia Minor) and other locations in Eastern Europe. The exact origin of Thracians is unknown, but it is believed that proto-Thracians descended from a purported mixture of Proto-Indo-Europeans and Early European Farmers, arriving from the rest of Asia and Africa through the Asia Minor (Anatolia). The proto-Thracian culture developed int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Rome
In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC) and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually dominated the Italian Peninsula, assimilated the Greek culture of southern Italy ( Magna Grecia) and the Etruscan culture and acquired an Empire that took in much of Europe and the lands and peoples surrounding the Mediterranean Sea. It was among the largest empires in the ancient world, with an estimated 50 to 90 million inhabitants, roughly 20% of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zlatiya (region)
Zlatia ( bg, Златия, often with a definite article: Златията, ''Zlatiata''; also ''Zlatiya'', ''Zlatija'') is a small geographic region in Northern Bulgaria. Zlatia is a low asymmetrical plateau in the northwestern part of the country, a subregion of the Danubian Plain. It lies between three rivers: the Tsibritsa to the west, the Ogosta to the east and the Danube to the north. The plateau's elevation is around 100–150 metres above mean sea level, the highest point reaching 176 m near the Danube. The soil is a fertile chernozem; no rivers cross the plateau, but by heavy rainfall the ravines are drained away to the east by the Ogosta river and ultimately into the Danube. Zlatia has been an Important Bird Area since 2005 (parts of it since 199and has been included in the European Union, EU's Natura 2000 ecological network. The protected area covers 434.987 square kilometre Although most of the region is composed of arable land, there are still some extant ...

Ogosta
The Ogosta ( bg, Огоста , Latin: ''Augusta''), is the largest river in Northwestern Bulgaria, a right tributary of the Danube. It originates at Chiprovska Mountain, 2,168 meters high section of the Western Balkan Mountains, at about an altitude of 1,760 meters, on the border with Serbia. The towns of Chiprovtsi, Montana, Bulgaria, Montana, and Miziya are situated on the river's banks. The Ogosta river is 147.4 km in length and is fed by 40 tributaries (including the Skat (river), Skat River) in a watershed of 3,157 square kilometers. The average water discharge in the lower course of the river is 18 cubic meters per second. Along the river's length there are 14 irrigation systems, 8 hydropower plants, and 13 dams. Although the river is used for domestic consumption, it does suffer from pollution, particularly from nitrate, nitrates. These come from the use of fertilizers that are not fully used by the plants. Other than that, there were intensive mining activities along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irri ...

Second
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discharge (hydrology)
In hydrology, discharge is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids (e.g. sediment), dissolved chemicals (e.g. CaCO3(aq)), or biologic material (e.g. diatoms) in addition to the water itself. Terms may vary between disciplines. For example, a fluvial hydrologist studying natural river systems may define discharge as streamflow, whereas an engineer operating a reservoir system may equate it with outflow, contrasted with inflow. Theory and calculation A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure. For measuring the discharge of a river we need a different method and the most common is the 'area-velocity' method. ...

Drainage Basin
A drainage basin is an area of land where 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 a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asp ...
