1. introduction considering the importance of lake urmia in the weather of northwest of iran, the present study, using dynamic modelling and simulation, investigates the consequences of the drying up of lake urmia on the climate parameter of downfall. 2. study area lake urima, considered the biggest pond in western asia, with a surface area of 5 thousand and 822 square kilometers, is the second...

Abstract The Urmia Lake National Park (NW Iran) represents a unique ecosystem owing to special ecological conditions prevailing the region. The Urmia Lake National Park comprises a range of normal to extreme environments, with variable range of salinity between 120-300 g/L. The present study was aimed to characterize ascomycetous yeast mycobiota inhabiting hypersaline soils in this region. Soi...

In the present study, nine species of Aspergillus, viz., A. alliaceus, A. ochraceus, A. persii, A. leproris, A. parasiticus, A. fumigatiaffinis, A. sydowii, A. niger, A. tubingensis and Eurotium amstelodami were obtained and identified from soils of the National Park of Urmia Lake, based on cultural and morphological characteristics. All of the species are newly recorded from hypersaline soils ...

Lake Urmia, Iran. There is widespread interest in restoring drying saline lakes. At Iran’s hypersaline managers have sought a uniform target lake level of 1274.1 m above sea to lower salinity below 263 g L?1 and recover Artemia sufficient densities support flamingos. We suggest that addressing broader range objectives will allow more flexibility for managing the lake. define eight restoration s...

One of the most important hydrological time series task is to determine if there is any trend in the data and how to achieve stationarity when there is nonstationarity behavior in data. Detecting trend and stationarity in hydrological time series may help us to understand the possible links between hydrological processes and global climate changes. In this study yearly, monthly and daily stream...

The main aim of the present study was to map of Urmia Lake water surface diminishing rates over a long-term period, and demonstrating the most recent surface of emerged salty alluvial plains. For this purpose, Landsat TM, ETM+ and OLI imageries, observing from 1984 to 2015, were progressively processed to generate most of the thematic models in tempo-spatial context. All multi-date satellite da...

the present research focuses on the changes of urmia lake level. for this purpose, two timescales have been considered. the trend changes of temperature, precipitation rate and quantitative values of climate type for the observational period from 1968 to 2011 (past scale) and from 2011 to 2100 (future scale) have been analyzed. general circulation model (gcm) is considered for simulating the va...
