This study evaluated the concentrations of organochlorine pesticides (OCPs) in inlet and outlet treatment plant Ahvaz city. For this purpose, six OCPs, including chlordane, dieldrin, dichlorodiphenyltrichloroethane, heptachlor, lindane, endrin were measured at three different sites during, 12 months. A gas chromatograph-mass spectrometer (GC-MS) device was applied for analysis determination tar...

Water resources are vital to the survival of living organisms and contribute substantially development various sectors. Climatic diversity, topographic conditions, uneven distribution surface water flows have made reservoirs one primary supply in Iran. This study used Landsat 5, 7, 8 data Google Earth Engine (GEE) for supervised monitoring dynamics reservoir eight Iranian dams (Karkheh, Karun-1...

Floods are among the natural disasters that cause human hardship and economic loss. Establishing a viable flood forecasting and warning system for communities at risk can mitigate these adverse effects. However, establishing an accurate flood forecasting system is still challenging due to the lack of knowledge about the effective variables in forecasting. The present study has indicated that th...

chah?rmah?l-o-bakhtiy?r? province has an area of some one percent of the area of iran and is situated in the northern basin of karun river, which is one of the most vital flows of the south-west iran. for various reasons, the region has been ignored in the national archeological studies. in a quick glance, the present study seeks to show the significance of the findings obtained in the course o...

in this study 485 specimen of garra rufa (heckel, 1843) from 29 populations from six river systems and basins including tigris, karkheh, karun, persis (helleh and mond), hormuz and maharlu were collected by a 5mm mesh sized seine net, anesthetized in 1% clove oil solution, fixed in 10% formalin and transferred to the laboratory for further investigations. some 28 morphometric, 25 morphometric p...

In this paper, a many-objective optimization algorithm was developed using SPEA2 for system of four reservoirs in the Karun basin, including hydropower, municipal and industrial, agricultural, environmental objectives. For purpose, 53 years available data, hedging rules were two modes: with without applying fuzzy logic. used to optimize coefficients first 43 data last 10 test optimized rule cur...
