evaluation of river discharges trends is very important for water resources management and design of irrigation and drainage networks. in this research, annual, seasonal and monthly trends of maroon river discharge were evaluated using the mann-kendall and sen’s slope estimator non-parametric tests and the regression analysis parametric test. for this purpose, river discharge data from five h...

this study was conducted to determine water stress tolerance of two iranian dudaim melons (kerman & birjand) and one iranian muskmelon (samsoury). throughout the experiment, three different levels of irrigation with three irrigation starting points (-50, -65 and -75 cb of matric potential) were employed. results indicated that water stress significantly affected yield, firmness, fruit sugars as...

the main goal of interpretation of potential fields (gravity and magnetic) data is determination of the buried source parameters including the depth, horizontal position, the structural index and the physical properties, which is magnetic susceptibility in the magnetic cases and density for gravity fields. for a large number of data it is so expensive modelling the data by using the inversion a...

introduction climate change happens due to abnormal changes of climate within the earth’s atmosphere and their consequences. one of the most significant effects of climate change is the irreversible damage to some floral species and forest ecosystems. tree species reflect the impact of climate changes on their ring width. generally, tree rings vary in size each year depending upon the environme...

regional analysis is one of the important methods for estimating the low flow in ungagged regions. investigation of the relations between effective factors of hydrological drought is the most important strategy to contrast and reduction of drought losses. in this study to analyze of low flow, the daily discharge data from 20 gauging stations with 25 years period (1988-2012) in the kashafroud ba...

this research was carried out for evaluation of competitive ability of some wheat cultivars (triticum aestivum l.) of recommended wheat in dargaz region with common weed of feral rye (secale cereale). experiment was conducted as factorial based on randomized complete block design with three replications in 2010-2011 growing season. experimental factors were included four wheat cultivars of says...

to study the effects of biofertilizers on physiological and morphological characteristics, as well on essential oil content in dragonhead (dracocephalum moldavica), an experiment was conducted at tarbiat modares university in 2009. the studied factors were: vermicompost (0, 15, 30% v/pot), azotobacter (inoculated and non-inoculated), and phosphatic biofertilizer (inoculated and non-inoculated)....
