glasswort(salicornia europaea l.) as an important halophyte plant is capable to accumulate nacl in aboveground part (fully edible) in considerable quantity. to evaluate the effect of irrigation levels and nitrogen fertilizer on the yield of seed and oil, and also harvest index of glasswort, a split plot experiment was conducted based on randomized complete block design with three replications a...

Lake Urmia Basin (LUB), in northwestern Iran, is under the influence of extreme degradation due to a number natural and anthropogenic factors. The existence critical for microclimate region as well quality human life wildlife, which necessitates an up-to-date holistic analysis its hydrological dynamics. In this premise, satellite-based Terrestrial Water Storage (TWS) received from GRACE mission...

Lake water level fluctuation is a function of hydro-meteorological components, namely input, and output to the system. The combination these components from in-situ remote sensing sources has been used in this study define multiple scenarios, which are major explanatory pathways assess lake levels. goal analyze each scenario through application balance equation simulate largest Iran, Urmia, sel...

Fast multi-output relevance vector regression (FMRVR) algorithm is developed for simultaneous estimation of groundwater and lake water depth the first time in this study. The FMRVR a analysis technique which can simultaneously predict multiple outputs multi-dimensional input. data used study collected from 34 stations located Urmia basin over 40-year period. performance model examined contrast ...

the study on water level fluctuation in the urmia lake has become of a great importance in recent years. this is due to the importance of the position of this lake as a natural heritage at an international level. the water level decrease at the urmia lake during the recent years has made it necessary to address the matter more than before. investigation and assessment of changes in the lake is ...

Nowadays, biometrical characterizations of Artemia cysts are used as one of the most important factors in the study of Artemia populations and intraspecific particularity; meanwhile these characters can be used as economical indices. For example, typically high hatching efficiency is possible due to the small diameter of cysts (high number per gram); therefore small diameter of cysts show somew...

In the present study, the cyanobacterial flora of Urmia Lake (NW Iran), one of the largest salt lakes in the world and adjacent rivers is investigated. Urmia Lake comprises different micro-organisms including cyanobacteria which have a major role in aquatic ecosystems. Cyanobacterial samples were collected in 2008–09 from Urmia Lake and its surrounding ecosystems. All samples were cultivated, i...

The water yield produced at the outlet of a sub-basin is combination multiple interacting land uses. In majority previous research, while accounting for effect use and cover (LULC) on yield, hydrologic components watershed have been attributed to dominant class within that sub-basin. We adopted an approach investigate interaction LULC (WYLD) using Johnson–Neyman (JN) method. soil assessment too...
