Abstract The influence of Karun river inflow on salinity intrusion from the Arabian Gulf towards upper reaches Shatt Al-Arab estuary was evaluated by using Mike11, a one-dimensional numerical modeling technique. simulations results indicated that, during moderate and low flow conditions river, freshwater at 10 40 m 3 /s, respectively, could be capable keeping extent to not exceeded confluence l...

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...

odonata fauna is poorly known in iran and most of the previous studies deal with northern parts of the country, studying adult specimens. we sampled karun river for aquatic insects in the city of ahvaz in south-west of iran during 2009–2011. as a result, 40 nymphs of one damselfly species and four dragonfly species of the order odonata comprising five genera from four families were recorded. al...

The Beshar River is one of the most important aquatic ecosystems in the upstream of the Karun watershed in south of Iran which is affected by point and non point pollutant sources . This study was done in order to evaluate the effects of pollutants activities on the water quality of the Beshar river and its aquatic ecosystems. This river is approximately 190 km in length and situated at the geo...

this study describes the length-weight and length-length relationships for 28 populations of garra ruffa in different basins of iran, including tigris, karkheh, karun, persis and hormuz. the length-weight relationships from most localities are reported here for the first time. for most populations the b value was not significantly different from 3, indicating an isometric growth, in a few, it w...

Floods are one of the most destructive natural disasters, causing financial and human losses every year. As a result, reliable Flood Susceptibility Mapping (FSM) is required for effective flood management reducing its harmful effects. In this study, new machine learning model based on Cascade Forest Model (CFM) was developed FSM. Satellite imagery, historical reports, field data were used to de...
