flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

To investigate the effect of different levels of salinity on yield of three cultivars of cotton, an experiment was performed for two years (2008-2009) as split plot, based on randomized complete blocks design with four replications, at Rudasht Agricultural Research Station, Isfahan Province, Iran. To prepare the salinity levels, mixtures of well water, Zayandehrud river water and drainage water...

In order to investigate the effect of salinity on the physiology of two cultivars of green and orange bell peppers, an experiment was conducted at the Isfahan University of Technology, Isfahan, Iran in 2019. The experiment was a factorial experiment in a completely randomized design in the greenhouse, in which treatments included four salinity levels (irrigation with normal water, irrigation wi...

In order to unravel the potential mitigating effects of seed priming on salt-stressed chickpea (Cicer arietinum), a 4-replicate factorial out-door completely random design pot experiment was conducted on Arman cultivar of chickpea at the research field of the Isfahan University of Technology, Isfahan (Latitude of 32° 38' North, Longitude of 51° 39' East, and an Altitude of 1620 m above sea lev...

rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
