Compliance with the drought, due to the complex nature of the phenomenon, depends on a variety of social, economic, environmental, infrastructure and management factors, and the development process of villages located in drought conditions also depends on several factors that are caused by drought conditions. The drying of Lake Urmia has also made the necessity and importance of adapting rural ...
GIS-based ordered weighted averaging and Dempster–Shafer methods for landslide susceptibility mapping in the Urmia Lake Basin, Iran Bakhtiar Feizizadeh a b , Thomas Blaschke a & Hossein Nazmfar c a Department of Physical Geography, Centre for Remote Sensing and GIS, University of Tabriz, Tabriz, Iran b Department of Geoinformatics (Z_GIS), University of Salzburg, Salzburg, Austria c Department ...
Urmia Lake, located in north-west of Iran, has been exposed to various threats such as drought, construction of dams, land use changes and increased global temperature. Due to the importance of Urmia Lake, it is feasible to conduct different kinds of studies to identify the problems of its watershed. The main objective of this study was to evaluate SWAT program’s ability to simulate runoff in U...
statistical modeling of future lake level under climatic conditions, case study of urmia lake (iran)
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...
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...
Urmia Lake in northwestern Iran has been facing critical water level shrinkage in recent years with serious environmental consequences. It is expected that with the current trend, the lake will be completely dried out in a few years from now. This study attempts to assess the impacts of human activities on water level fluctuations of Urmia Lake by developing a comprehensive hydrologic simul...
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...
increased salinity stress because of rising temperature as a result of global warming. High salinity enhances plants photorespiration and affects its physiology, but Salicornia europaea L. in Urmia Lake has adapted to grow, propagate and occupy increasingly exposed saline habitats. Plant and soil samples were collected in triplicate plots from different sites of retreated beds of Urmia Lake in ...
Urmia lake due to the presence of various species of wildlife, species of vegetation on the islands, create a natural balance in the Azerbaijan region, tourist, recreational and social value, medical value, reserve of the Bio sepehr and as well as a wetland of international importance is special. Over the last few decades , use remote sensing technology to detect trends such changes various re...
