in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
To determine the effects of salinity and boron excess in irrigation water on relative growth rate (RGR), net assimilation rate on a leaf weight basis (NAR), and leaf weight ratio (LWR) of pistachio, three pistachio rootstocks (Badami -Zarand, Sarakhs and Ghazvini) were used. Rootstocks were grown in soil in eight-liter polyethylene pots. Sodium chloride treatments were 0, 75,150 and 225 mM NaCl...
Background & Aims of the Study: We evaluated corrosion and scaling potential of water treated by “Takab city (Western Iran) water treatment plant (called Chahar Tagh facilities)” using field observation of water treatment plant, and study of physical and chemical parameter values of water. Materials & Methods: In this cross-sectional study, during a 10-month period (fro...
In order to evaluate of the photosynthetic traits of lentil cultivars under water deficit conditions an experiment was conducted as a factorial arrangement in a completely randomized design with three replications in pot cultivation with four cultivars including Gachsaran, Kimia, Ziba, Robat and four stress levels of 25, 50, 75 and 100% of field capacity. Results showed that in all three phenol...
One-year-old rooted cuttings of olive (Olea europaea L. cvs. Frantoio and Leccino) were grown either hydroponically or in soil in a greenhouse. Plants were exposed to NaCl treatments (0, 100, and 200 mM) for 35 days, followed by 30 to 34 days of relief from salt stress to determine whether previously demonstrated genotypic differences in tolerance to salinity were related to water relations par...
in order to study the effects of soil and foliar application of fe-eddha on some biochemical and physiological traits in safflower under two irrigation regimes an experiment was conducted in 2008 growing season in research field of faculty of agriculture, shahed university. the experimental design was a split-plot based on randomized complete blocks with four replications. mainplots consisted o...

The effects of waterlogging the soil on leaf water potential, leaf epidermal conductance, transpiration, root conductance to water flow, and petiole epinasty have been examined in the tomato (Lycopersicon esculentum Mill.). Stomatal conductance and transpiration are reduced by 30% to 40% after approximately 24 hours of soil flooding. This is not due to a transient water deficit, as leaf water p...
mungbean (vigna radiata (l.) wilczek) or green gram as a dryland grain legume is exposed to varied timings and severity of drought stress, resulting in variability in photoassimilate production. in order to evaluate some physiological responses in one mungbean cultivar to timing and severity of drought stress, a 3-replicate rcbd (randomized complete block design) field experiment was carried ou...
Canopy interception, throughfall, stemflow, and runoff have received considerable attention during the study of water balance and hydrological processes in forested ecosystems. Past research has either neglected or underestimated the role of hydrological functions of litter layers, although some studies have considered the impact of various characteristics of rainfall and litter on litter inter...
