Extensive arsenic contamination of groundwater, rivers, and agricultural farms has led to widespread poisoning consequent problems associated with health economy. In recent years, many studies have been performed understand bacterial detoxification metabolism which paved the way for bioremediation applications. This study attempted isolate characterize arsenic-resistant bacteria from drying Urm...

identifying the change trends in forms of land surface is one of the main topics in geomorphic system. in this view, we try to assess the stability level of geo systems, boundary changes, instability and prediction of surface forms and processes response. this paper tries to conduct a comparative analysis on the geomorphic equilibrium paradigms, critical thresholds, environmental and natural ha...

Abstract This study investigates the future changes in precipitation extreme indices Lake Urmia Basin during period 2021–2100 compared to base (1987–2016), based on Coupled Model Intercomparison Project Phase 5 models. Trend analysis was performed using Mann–Kendall test and Sen's estimator. The output of these models downscaled by Long Ashton Research Station Weather Generator method for repre...

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,...

the expansion of grey- black pottery tradition in the iranian plateau, on the basis of iron age theory of cultural dynamism, was emerged by the end of the 2nd millennium bc. such a pottery tradition is regarded as a cultural sign to point migrants who entered in the iranian plateau from the northern outside of caucasus the major. according to the theory, the migrants passed the river valley of ...

the purpose of this research was to analyze the impact of agronomic land use change to orchard in the west of urmia lake basin. the target population was about 12000 consisting of all the farmers in the west of urmia lake basin that changed their agronomic land use to orchard. using cochran’s formula and stratified random sampling method, 150 apple and grape growers were chosen. required data w...
