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...
Abstract The existence of reliable rain-gauge networks is a necessity in managing water sources and the relevant environmental issues any basin. present study aimed to investigate network rank stations Tazehkand sub-basin southwest Lake Urmia, Iran, using entropy–copula approach data obtained from six Siminehrood basin Northwestern Iran between 1981 2019. interaction effects were investigated c...
Sustainable development of agriculture is facing with several challenges such as climate change resulting change in the pattern of weather parameters as well as crop water requirements. In this research, due to the important role of agricultural activities whitin Urmia Lake Basin in the production of various agricultural products such as wheat, the possibility of supplying the plant's water req...
the issue of water resources and their effect on human life doesn't need any analysis and reasoning. however, such factors as population growth, improved quality of life and development of urbanization along with improved industrial and technological dimensions of human life have necessitated logical and reasonable planning for optimal use of water and water basins of the world. these fact...
Lake Burullus is one of the vulnerable Egyptian coastal lakes suffering from high level of aquatic plant, over fishing, expansion in fish farming and agricultural drainage discharges and increasing of human activities. Eutrophication in water bodies of the lake is associated with growth of the different hydrophytes which have direct effects on Euro-Asian Palaearctic migrants passing Egypt. The ...
Hydrological predictions in ungauged lakes are one of the most important issues in hydrological sciences. The habitat of the Relict Gull (Larus relictus) in the Erdos Larus relictus National Nature Reserve (ELRNNR) has been seriously endangered by lake shrinkage, yet the hydrological processes in the catchment are poorly understood due to the lack of in-situ observations. Therefore, it is neces...
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 ...
In this study, the Frequency and the spell of rainy days was analyzed in Lake Uremia Basin using Markov chain model. For this purpose, the daily precipitation data of 7 synoptic stations in Lake Uremia basin were used for the period 1995- 2014. The daily precipitation data at each station were classified into the wet and dry state and the fitness of first order Markov chain on data series was e...
[1] The formation of large impact basins (diameter D ≥ 300 km) was an important process in the early geological evolution of Mercury and influenced the planet’s topography, stratigraphy, and crustal structure. We catalog and characterize this basin population on Mercury from global observations by the MESSENGER spacecraft, and we use the new data to evaluate basins suggested on the basis of the...
