Lake Urmia
Lake Urmia; az, اۇرمۇ گؤلۆ, script=Arab, italic=no, Urmu gölü; ku, گۆلائوو رمیەیێ, Gola Ûrmiyeyê; hy, Ուրմիա լիճ, Urmia lich; arc, ܝܡܬܐ ܕܐܘܪܡܝܐ is an endorheic salt lake in Iran. The lake is located between the provinces of East Azerbaijan and West Azerbaijan in Iran, and west of the southern portion of the Caspian Sea. At its greatest extent, it was the largest lake in the Middle East and the sixth-largest saltwater lake on Earth, with a surface area of approximately , a length of , a width of , and a maximum depth of . By late 2017, the lake had shrunk to 10% of its former size (and 1/60 of water volume in 1998) due to persistent general drought in Iran, but also the damming of the local rivers that flow into it, and the pumping of groundwater from the surrounding area. This dry spell was broken in 2019 and the lake is now filling up once again, due to both increased rain and water diversion from the Zab River by the Lake ...

Salmas
Salmas ( fa, سلماس; ; ; ; syr, ܣܵܠܵܡܵܣ, Salamas) is the capital of Salmas County, West Azerbaijan Province in Iran. It is located northwest of Lake Urmia, near Turkey. According to the 2019 census, the city's population is 127,864. The majority of the population is composed of Azerbaijanis and Kurds with some Armenians, Assyrians, and Jews. History Etymology and early history According to Encyclopædia Britannica the earliest historic recognition of Salmas could be found at the time of Ardashir I's reign (224–242 AD) via a petroglyph of him on horseback while receiving surrender of the Parthian personage. In another contribution by Britannica, on an animated political map of Sassanid Empire at the time of Shapur I's reign (240–270 AD), Salmas is markedly acknowledged as one of the renown and apparently important cities of the empire with the same original name as now. There is a speculation that the nickname of the city, Shapur, might be derived from the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Catchment Area
In human geography, a catchment area is the area from which a location, such as a city, service or institution, attracts a population that uses its services and economic opportunities. Catchment areas may be defined based on from where people are naturally drawn to a location (for example, labour catchment area) or as established by governments or organizations for the provision of services. Governments and community service organizations often define catchment areas for planning purposes and public safety such as ensuring universal access to services like fire departments, police departments, ambulance bases and hospitals. In business, a catchment area is used to describe the influence from which a retail location draws its customers. Airport catchment areas can inform efforts to estimate route profitability. Types of catchment areas Catchments can be defined relative to a location and based upon a number of factors, including distance, travel time, geographic boundaries or popu ...

Meter
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redefiniti ...

Phytoplankton
Phytoplankton () are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems. The name comes from the Greek words (), meaning 'plant', and (), meaning 'wanderer' or 'drifter'. Phytoplankton obtain their energy through photosynthesis, as do trees and other plants on land. This means phytoplankton must have light from the sun, so they live in the well-lit surface layers (euphotic zone) of oceans and lakes. In comparison with terrestrial plants, phytoplankton are distributed over a larger surface area, are exposed to less seasonal variation and have markedly faster turnover rates than trees (days versus decades). As a result, phytoplankton respond rapidly on a global scale to climate variations. Phytoplankton form the base of marine and freshwater food webs and are key players in the global carbon cycle. They account for about half of global photosynthetic activity and at least half of the oxygen production, despite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Iran
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, " burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, s ...
