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...

chaos theory discusses unstable and non-periodic behavior of non-linear fluctuating dynamicsystems. since evaporation level variations of lakes have a dynamic identity, chaos theory can have a uniquerole in collecting data of these variations. therefore it is an important and challenging problem in the field ofplanning and qualitative and quantitative management of urmia lake to verify whether ...

Abstract In this study, two models of Random Forest and copula-based simulation were used to evaluate the accuracy efficiency IHACRES rainfall-runoff model in simulating daily discharge Siminehroud River south Lake Urmia basin, Iran. A trivariate was created using discharge, rainfall temperature data on a scale period 1992–2018. Vine family their conditional densities implement model. By calibr...

INTRODUCTION overall relief greater than 400 m. It is a major component of the Laurentian Great Lakes catchment area draining The Lake Huron basin (Huron basin), which includes via the St. Lawrence River to the Atlantic Ocean (Figs 1 Georgian Bay and the Nipissing lowland to the northeast, and 2). The Huron basin presently receives inflow from extends 500 km north-south and 450 km east-west wit...

Karucia sublacustrina a new species of freshwater snails (Hydrobiidae, Gastropoda) is described based on material collected from Skadar Lake (Montenegro, Albania). The new species belongs to monotypic genus Karucia gen. n. The shell morphology and body shape of the new genus resembles Radomaniola Szarowska, 2006 and Grossuana Radoman, 1973, from which it differs in the larger shells with relati...

Drying lakes have become a new source of dust, causing severe problems in surrounding areas. From 2000 to 2017, statistical study was conducted on Lake Urmia Iran the Middle East. The results indicated significant increase annual number dusty days stations around lake and mean aerosol optical depth (AOD) at 550 nm. sharp decrease snowfall rate over area since 2007 has been linked lake’s decreas...

   Urmia Lake is one of the two large hypersaline lakes in the world which have Artemia. It is located in northwest of Iran. Due to a decrease in water inflow and volume, the salinity of Urmia Lake has reached to more than 300 g.l-1 since 2001. The increased salinity has greatly influenced biological aspects of the lake, and caused the lake undergoes at critical conduction. The aim of the prese...
