Abstract of the Thesis

Lake Urmia was the second largest permanent hyper-saline lake in the World and the biggest in Middle East. The alerting situation of the lake pushed the authority such that the United Nations declared it as the wetland of international importance and World’s biosphere reserve. In late 1990’s water level in the lake started to decline with a sharp trend such that a wasteland of salty desert was conceptualized for the lake’s future. Many researchers around the world tried to model, suggest or decode the fact behind the lake’s atrophy mostly accused by miss-management, dam construction, development of agricultural zones, climate change etc. as the main reason for the lake atrophy.

In this study, a lake water budget approach using hydro-meteorological variables; precipitation, evaporation, runoff and groundwater, was considered. For this aim, data from meteorological stations, stream-flow gauging stations and groundwater wells were gathered. Data were analyzed and a data inventory was obtained. The data inventory consists of 253 meteorological stations, 156 stream-flow gauging stations, 593 groundwater wells and 1 lake water level station all scattered over the Lake Urmia basin. Precipitation and evaporation were taken from meteorological stations. In this study, 7 meteorological stations, 18 stream-flow gauging stations and 9 groundwater wells were considered together with the lake water level station. The selected stations and groundwater wells are close to the lake and scatter around it. 

Data in the selected stations and groundwater wells were checked against any missing data periods. Most of the stations were found with missing data. Groundwater wells have particularly long period of time with no data. For getting a common period for the analysis, missing data were reconstructed by a frequency domain analysis using decomposition. With this method, each time series of each station and groundwater well were decomposed into its components; trend, cycle, seasonality and randomness. An additive decomposition method was chosen. Observed time series was divided into calibration and validation parts. The decomposition method was used to fit a model to the calibration time series and to validate it then on the validation time series. Once validated, the model was run to reconstruct the missing data. This procedure was applied on all time series of precipitation, evaporation, runoff and groundwater. The observed and reconstructed precipitation, evaporation, runoff and groundwater time series were used to calculate lake water level. The calculated lake water level was compared with the observed lake water level. They were found in a very good agreement. This has been considered as a further validation of the reconstructed missing data. 

Observed and reconstructed hydro-meteorological data were used together to develop models for forecasting lake water level. In the model, lake water depth was considered instead of lake water level. For this aim, two methods were combined. First, lake water depth was regressed on independent variables; precipitation, evaporation, runoff and groundwater. The second step is the development of stochastic model for each variable. Auto-regressive integrated moving average (ARIMA) models were used. A number of models were tested and finally the best models were determined based on performance criteria for each variable. The number of parameters was kept at minimum for the sake of parsimony. As the final step in the modeling, not hydro-meteorological variables (precipitation, evaporation, runoff and groundwater) but their selected stochastic models were inserted into the regression model developed at the very beginning step. This is defined as regressive-stochastic depth model.

Alternatively, difference in the lake water levels of two subsequent months was taken into account instead of the lake water depth when the regression model is developed in the first step. Because lake water depth can mask change in the lake water level as they have different orders of magnitudes.

From this study it is seen that Lake Urmia is under a serious atrophy problem that should be studied in a long-term interdisciplinary approach. Lake Urmia has a considerably well documented data although record periods without data may become problematic. The frequency domain analysis can be a tool to satisfactorily reconstruct the missing data in the hydro-meteorological time series. Lake water level models can be developed based on either lake water depth or the difference in the lake water level between subsequent months. Due to the order of magnitude difference between the depth and the depth difference, it is clear that depth models can mask the effect of each input variable; precipitation, evaporation, runoff and groundwater, on the lake water level. Therefore, depth difference models should be preferred for the sake of understanding the physical process in the lake water level precisely. Regressive-stochastic models were found successful in calculating the lake water level. In the proposed regressive-stochastic models, only previously observed hydro-meteorological data are needed. This is a good opportunity for one to be able to estimate the next month lake water level. This will help us decision makers to act in advance.

As a future suggestion, the lake and its watershed should be investigated through an interdisciplinary approach. As the change is a continuous process it is suggested that any model proposed should be revised every several years and/or after any major change happens in the basin.

Diminishing of surface of lake Urmia

Lake Urmia is an endorheic salt lake in northwestern Iran near Iran's border with Turkey.[1][2] The lake is between the provinces of East Azerbaijan andWest Azerbaijan in Iran, and west of the southern portion of the Caspian Sea. At its full size, it was the largest lake in the Middle East and the sixth largest saltwater lake on earth with a surface area of approximately 5,200 km² (2,000 mile²), 140 km (87 mi) length, 55 km (34 mi) width, and 16 m (52 ft) depth.[3]
Lake Urmia along with its once approximately 102 islands are protected as a national park by the Iranian Department of Environment.
Along with Lake Van and Lake Sevan, Urmia was considered one of the three great lakes of the historical Armenian Kingdom, collectively referred to as the 'Seas of Armenia'.

Names and etymologies[edit]



Currently the lake is named after the provincial capital city of Urmia, originally an Assyrian name meaning Puddle of water. However, in the early 1930s, it was called Lake Rezaiyeh (Persian: دریاچه رضائیه‎) after Reza Shah Pahlavi, it was after the Iranian Revolution in the late 1970s, that the lake was renamed Urmia. Its ancient Old Persian name was Chichast (meaning, "glittering"–a reference to the glittering mineral particles suspended in the lake water and found along its shores). In medieval times it came to be known as Lake Kabuda (Kabodan),[4] from the word for "azure" in Persian, or 'կապույտ' ("Kapuyt/Gabuyd") in Armenian. The Latin name was Lacus Matianus so it is referred to in some texts as Lake Matianus or Lake Matiene.
Locally, the lake is referred to in Persian as دریاچه ارومیه, Daryāche-ye Orūmiye; inAzerbaijani as Urmu gölü, ﺍﻭﺭﻣﻮ ﮔﺆﻟﻮ, and in Kurdish as Wermy. The Armenianname is Կապուտան ծով, Kaputan ts'ov.

History[edit]


O
ne of the early mentions of Lake Urmia is from the Assyrian records from 9th century BCE. There, in the records of Shalmaneser III (reign 858–824 BCE), two names are mentioned in the area of Lake Urmia: Parsuwash (i.e. the Persians) and Matai (i.e. the Mitanni). It is not completely clear whether these referred to places or tribes or what their relationship was to the subsequent list of personal names and "kings". But Matais wereMedes and linguistically the name Parsuwash matches the Old Persian word pārsa, an Achaemenid ethnolinguistic designation.[5]
The lake was the center of the Mannaean Kingdom. A potential Mannaean settlement, represented by the ruin mound ofHasanlu, was on the south side of the lake. Mannae was overrun by the people who were called Matiani or Matieni, anIranian people variously identified as Scythian, Saka, Sarmatian, or Cimmerian. It is not clear whether the lake took its name from the people or the people from the lake, but the country came to be called Matiene or Matiane, and gave the lake its Latin name.
In the last five hundred years the area around Lake Urmia has been home to Iranians, Kurds, Assyrians, Armenians, andAzeris.

Chemistry[edit]


The main cations in the lake water include Na+, K+, Ca2+, Li+ and Mg2+, while Cl−, SO42−, HCO3− are the main anions. The Na+ and Cl− concentration is roughly four times the concentration of natural seawater. Sodium ions are at slightly higher concentration in the south compared to the north of the lake, which could result from the shallower depth in the south, and a higher net evaporation rate.
The lake is divided into north and south, separated by a causeway in which a 1.5-kilometre (0.93 mi) gap provides little exchange of water between the two parts. Due to drought and increased demands for agricultural water in the lake's basin, the salinity of the lake has risen to more than 300 g/litre during recent years, and large areas of the lake bed have been desiccated.[6]

Lake Urmia is home to some 212 species of birds, 41 reptiles, 7 amphibians, and 27 species of mammals,[9] including the Iranian yellow deer.[10] It is an internationally registered protected area as both a UNESCO Biosphere Reserve[8] and a Ramsar site.[11] The Iranian Dept. of Environment has designated most of the lake as a National Park.[12]
The recent drought has significantly decreased the annual amount of water the lake receives. This in turn has increased the salinity of the lake's water, lowering the lake viability as home to thousands of migratory birds including the large flamingo populations. The salinity has particularly increased in the half of the lake north of the causeway.
The lake is marked by more than a hundred small, rocky islands, which serve as stopover points during the migrations of several wild birds including flamingos, pelicans,spoonbills, ibises, storks, shelducks, avocets, stilts, and gulls.
By virtue of its high salinity, the lake no longer sustains any fish species. Nonetheless, Lake Urmia is considered a significant natural habitat of Artemia, which serve as food source for the migratory birds such as flamingos.[13] In early 2013, the then-head of the Iranian Artemia Research Center was quoted that Artemia Urmiana had gone extinct due to the drastic increases in salinity. However this assessment has been contradicted.[14]
The lake is a major barrier between two of the most important cities in West Azerbaijan and East Azerbaijan provinces, Urmia and Tabriz. A project to build a highway across the lake was initiated in the 1970s but was abandoned after the Iranian Revolution of 1979, having finished a 15 km causeway with an unbridged gap. The project was revived in the early 2000s, and was completed in November 2008 with the opening of the 1.5 km Urmia Lake Bridge across the remaining gap.[15] The highly saline environment is already heavily rusting the steel on the bridge despite anti-corrosion treatment. Experts have warned that the construction of the causeway and bridge, together with a series of ecological factors, will eventually lead to the drying up of the lake, turning it into a salt marsh which will directly affect the climate of the region. Lake Urmia has been shrinking for a long time, with an annual evaporation rate of 0.6m to 1m (24 to 39 inches). Although measures are now being taken to reverse the trend[16] the lake has shrunk by 60% and could disappear entirely.[16] Only 5% of the lake's water remains.[17]

Bridge construction over Lake Urmia in 2005
On 2 August 2012, Mohammad-Javad Mohammadizadeh, the head of Iran's Environment Protection Organization, announced that Armenia has agreed on transferring water from Armenia to counter the critical fall in Lake Urmia's water levels, remarking that "hot weather and a lack of precipitation have brought the lake to its lowest water levels ever recorded". He added that recovery plans for the lake include the transfer of water from Eastern Azerbaijan Province. Previously, Iranian authorities had announced a plan to transfer water from the Aras River, which borders Iran and Azerbaijan; the 950-billion-toman plan was abandoned due to Azerbaijan's objections.[18]
In July 2014, Iran President Hassan Rouhani approved plans for a 14 trillion rial program (over $500 million) in the first year of a recovery plan. The money is supposed to be used for water management, reducing farmer's water use, and environmental restoration. Several months earlier, in March 2014, Iran's Department of Environment and the United Nations Development Programme (UNDP) issued a plan to save the lake and the nearby wetland, which called for spending $225 million in the first year and $1.3 billion overall for restoration.[19]
The Silveh Dam in Piranshahr County should be complete in 2015. Through a tunnel and canals it will transfer up to 121,700,000 m3 (98,700 acre·ft) of water from the Lavin River in the Little Zab basin to Lake Urmia basin annually.[20][21][22]

Palaeoecology[edit]

A palynological investigation on long cores from Lake Urmia has revealed a nearly 200 kyr record of vegetation and lake level changes. The vegetation has changed from the Artemisia/grass steppes during the glacial/stadialperiods to oak-juniper steppe-forests during the interglacial/interstadial periods. The lake seems to have had a complex hydrological history and its water levels have greatly fluctuated in the geological history. Very high lake levels have been suggested for some time intervals during the two last glacial periods as well as during both the Last Interglacial as well as theHolocene. Lowest lake levels have occurred during the last glacial periods.

Islands[edit]

Lake Urmia has approximately 102 islands.[23] See List of Lake Urmia's islands.
The lake's largest island, Shahi Island, is the burial place of Hulagu Khan, the grandson of Genghis Khan and the sacker of Baghdad. In 1967, the Iranian Department of Environment sent a team of scientists to study the ecology of Shahi Island. Various results of the study which included the breeding habits of brine shrimp were published by Javad Hashemi in the scientific journal, Iranian Scientific Sokhan.

Basin rivers[edit]

Environmental rallies[edit]

Recently, Lake Urmia faces the danger of drying out and the local Azeri population holds the Iranian regime accountable suspecting that the neglect for Lake Urmia’s environmental problems stems from the Iranian government’s deliberate policy to depopulate the area densely populated by an ethnic minority – the Azerbaijani people.[24]
  • On 2 April 2010 and 2011, and after several callings from Tractor Sazi F.C.'s fans in stadiums[25][26] and internet sites, protest demanding that the government take action to save Lake Urmia was held in Tabriz, Urmia, on the lake beach, and on top of the lake bridge. As a result, dozens of people were arrested by security forces.[27][28][29]
  • In August 2011, after the Iranian parliament dropped two emergency cases for reviving the lake, a number of soccer fans at Tabriz derby (soccer match between Tractor Sazi F.C. and Shahrdari Tabriz F.C.) were arrested for shouting slogans in favor of protecting the lake.[30] Later that same week, Iranian Azerbaijanians scheduled a protest against the parliament move. Despite the capture of more than 20 activists by security forces the day before the protest, numerous people attended the event in Urmia and a number of clashes with police were reported[31][32]
  • On 3 September 2011, Iranian Azerbaijanians demonstrated for second week in a row to protect Lake Urmia.[33] The protests in Tabriz and Urmia reportedly followed parliament's rejection of rescue plan, and security forces used violence to break up environmental rallies as protesters demanded action to save Lake Urmia,[34] and according to West Azerbaijan's governor, at least 60 supporters of the lake were arrested just in Urmia and dozens in Tabriz because, according to an Iranian official, they had not applied for a permit to organize a demonstration.[35] On August 2014 a protest campaign for saving the dying lake appeared on a video posted on social media showing a girl speaking in her native language Azeri Turkish " I'm from South Azerbaijan, for saving (to save) Lake Urmia and because of (Iranian president) Mr. Rouhani's failure to keep his promise on saving Lake Urmia, I'm calling him for the Salt Bucket Challenge" then pouring a bucket of salt on herself.[36]
 

In popular culture[edit]

For Azeri Turks the fate of Lake Urmia is a national, social, and economic issue and regarded as part of the Azerbaijani civilization.[38] Lake Urmia was the setting of the fictional Iranian film The White Meadows (2009), which featured fantastic-looking lands adjacent to a salt sea. There are many popular songs about Lake Urmia in Azeri Turkish such as "Urmu Golu Lay Lay"[39]
