Urmia Lake, which is the second largest permanent hypersaline lake in world, shrinking recent decades. Since accurate spatial information about essential to managing current and emerging crises of lake, this study used Lake satellite images time-series investigate drought trends by analyzing via Artificial Neural Networks (ANN). The proposed approach comprising following four steps. First, year...

Recently, hypoxia has become serious in Lake Biwa due to progressing of global warming. In this study, we determined Mn and As concentrations and their speciation in lake bottom water and sediments in June and December to elucidate their geochemical behaviors. Lake bottom water and sediment samples were collected from seven stations in the northern basin of Lake Biwa. In sediments, clear enrich...

Many saline lakes throughout the world are shrinking due to overexploitation of water in their drainage basins. Among them two world’s largest lakes, U.S.A.’s Great Salt Lake, and Iran’s Lake Urmia. Here we provide a comparative analysis desiccation these that provides insights on management decisions may help save relevant lake worldwide. Urmia were once remarkably similar size, depth, salinit...

osteological features are important to study the taxonomy and phylogenetic relationship of fishes. since there is no information is available about osteological features of squalius orientalis , therefore this study was aimed to provide a detailed description of the osteological features of this species from the urmia lake basin of iran and comparing it with population of s. orientalis from the...

abstract recent global warming has led to a change in the global hydrological cycle and an increase in extreme events such as flood and drought at the global and continental scales. however, at the regional scale, the magnitude of warming and the resulting changes in water resources are different from one region to another. unlike air temperature whose increase is evident throughout the world, ...

Precise forecasting of streamflow is crucial for the proper supervision water resources. The purpose present investigation to predict successive-station using Gated Recurrent Unit (GRU) model and quantify impact input information (i.e., precipitation) uncertainty on GRU model’s prediction Generalized Likelihood Uncertainty Estimation (GLUE) computation. Zarrineh River basin in Lake Urmia, Iran,...

Present study aims to unravel the hydro geochemical interaction of sediment and water of Saheb bandh lake, West Bengal, India with an emphasis on heavy metal assessment. Lake water belongs to Ca2+–HCO3− type hydro geochemical faces and water-rock interaction primarily controls the lake water chemistry. Based on different Hydro chemical characteristics it is suggested that silicate weathering is...
