Karun River is the largest and most watery river in Iran. This river is the longest river which located just inside Iran and Ahvaz Metropolis drinking water supplied from Karun River as well (fa.alalam.ir). Karun River as the main source of water treatment plants in Ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

Original scientific paper Studies on the evolution of paleo-channels in coastal areas are important for submarine engineering construction and to reveal changes in the global paleoenvironment. Thus, to explore the characteristics of paleo-channels during the late Last Glaciation in the western South Yellow Sea, digital terrain analysis method and ArcGis river extraction function were employed, ...

in order to study of barely and wheat cultivars tolerance to metribuzin, a factorial experiment was conducted as a completely randomized design, with three replications in greenhouse of agricultural research at ferdowsi university of mashhad. treatments included wheat cultivars (backcross roshan, cross arvand, bahar, sepahan, gascosion, sayonez, bam garmsiry, garmsiri, ghods, pishtaz, chamran a...

this study was performed for determine stability of the 18 promising barley lines and two check lines nosrat and mb-86-5 in six parts of the temperate zone including karaj, isfahan, birjand, varamin, zarghan and nishapur based on randomized complete block design)rcbd( with three replications and in two cropping seasons (2009-2011). following combined analysis, grain yield stability assessment w...

A large amount of accurate river cross-section data is indispensable for predicting river stages. However, the measured river cross-section data are usually sparse in the transverse direction at each cross-section as well as in the longitudinal direction along the river channel. This study presents three algorithms to resample the river cross-section data points in both the transverse and longi...

River systems are valuable to human beings; meanwhile, they are intensively influenced by human activities, especially urbanization. In this study, based on the data derived from topographic maps and remote sensing images, the temporal and spatial change of river system geomorphology in the Taihu Region over the past 50 years was investigated in conjunction with urbanization. Results demonstrat...

We determined levels of hepatic cytochrome P4501A (CYP1A) mRNA, hepatic DNA adducts, and fluorescent aromatic compounds (FACs) in bile, a measure of exposure to polyaromatic hydrocarbons, in Atlantic tomcod from six river systems ranging from highly polluted to relatively pristine on the northeast North American coast (the Hudson River, New York; the St. Lawrence River, Quebec; the Miramichi Ri...

This study proposed a natural-rule-based-connection (NRBC) method to connect river segments after water body detection from remotely sensed imagery. A complete river network is important for many hydrological applications. While water body detection methods using remote sensing are well-developed, less attention has been paid to connect discontinuous river segments and form a complete river net...
