| 1 | Gray Water Measurement and Feasibility of Retrieval Using Innovative Technology and Application in Water Resources Management in Isfahan-Iran显示文摘Reuse of wastewater for agriculture and green spaces purposes is significant.A mean yearly precipitation in Esfahan is 150 mm.The drinking water and agriculture usually used underground resources in the city.Gray water recycling is known as a suitable option today.Delivering all the water requirements of a home from refined water rises the cost of water.Whereas the essential water quality for garden,toilet and irrigation is less than drinking water.Therefore,the aim of this study is to analyze the evaluation of gray water and estimate the amount of recycle gray water which can use for drinking water with innovation method in Esfahan region in Iran.Previous studies did not measure the value of recycling gray water with new method of waste water treatment that can use for drinking purpose.In this study,gray water in Esfahan city is measured and technical aspects of its recycling is examined.Because of the lack of referable guidelines and official technical reports,studies from other similar countries applied in this study and on the basis of which the amount of recoverable gray water was calculated.Evaluations indicates that the overall recovery of gray water in Esfahan saves nine million cubic meters of water.The price of the rial of this value established on water is 190 billion Rials.Given the lack of water sources in Esfahan,the recycle of gray water seems to be a good option,however more research is required to select a recovery strategy. | Safieh Javadinejad Rebwar Dara Forough Jafary | 2020 | Journal of Geographical Research2020，3，2： | 3 |
| 2 | Effect of Precipitation Characteristics on Spatial and Temporal Variations of Landslide in Kermanshah Province in Iran显示文摘Landslide can be defined as the mass movement of sloping slopes under the influence of mass gravity and its stimuli such as earthquakes,floods and flood plains.This phenomenon is one of the natural hazards that every year causes a lot of financial and financial losses in mountainous,rain-fed and seismic areas.Detection of time and the magnitude of landslides are necessary to understand the causes of landslide and to warn potential hazards.In this research,the amount of landslide displacement in Kermanshah province was evaluated by the characteristics of rainfall.To this end,a network of fixed points in and out of the slipping mass of 20 points was created to monitor the amount of displacement on different slip load users and the amount of displacement of each point in 5 time intervals using the Global Positioning System for two-dimensional GPS measurement.The results of the 511-day follow-up showed that the total horizontal displacement of the moving points in the 5 intervals measured at 1658 mm has a monthly displacement rate of 112 mm.Also,the total vertical displacement of moving points at the same time is 899 mm,with a monthly movement rate of 71 mm.Then,precipitation variances such as rainfall,rainfall,precipitation duration,maximum rainfall intensity in the intervals of 10,20,30 and 60 minutes and the average rainfall intensity were calculated and extracted for each of the 5 time periods.The drawing of the vectors of points on the topographic map of the area indicated that the direction of mass movement is in the direction of elevation gradient of the region.The results showed that only the precipitation severity with the landslide had a good correlation.The landslide movement had the highest correlation with average rainfall intensity(R=0.85)and with maximum 30 minutes rainfall(R=0.67),respectively,and other rainfall characteristics like amount,duration,and type of rainfall had not significantly correlated with movement of landslides. | Safieh Javadinejad Rebwar Dara Forough Jafary | 2019 | Journal of Geographical Research2019，2，4： | 2 |
| 3 | Climate Change Management Strategies to Handle and Cope with Extreme Weather and Climate Events显示文摘Increasing the concentration of greenhouse gases causes rising in globalwarming and carbon dioxide emissions. With further efforts to reducecarbon dioxide, it is possible to prevent the warming of the earth, but theeffects of climate change that we have already created can not be reduced.Recent observed and predicted alterations in the global climate require adouble policy to react to the decline in climate alteration and its adjustment(coexistence) to explain the key factors and their effects. Measuresto reduce climate alteration through decreasing greenhouse gas releasesor removing them from the atmosphere are possible. Execution of morereduction measures at the present time will require less adaptation in thefuture. Meanwhile, inadequate measures to curb climate change presentlyincrease the risk of catastrophic consequences, so that adjustment costs willrise unreasonably and adaptive capacity will face further constraints. Climatechange adaptation measures concentrate in increasing our capabilityto deal with or prevent damaging effects or the use of new circumstances.Increasing temperature and changes visible today due to climate changemean that adaptation strategies should be applied. In this paper, strategiesfor reducing climate change and adaptation are reviewed and various strategiesare presented. Meanwhile, this paper looks at the economies affectedby climate change, our involvement to climate alteration, and the ways inwhich the economy has influenced climate change and the ways in which itcan provide logical options. | Safieh Javadinejad Rebwar Dara Forough Jafary Neda dolatabadi | 2020 | Journal of Geographical Research2020，3，4： | 0 |
| 4 | Droughts and the Impacts of Dry Spells in North of Iraq显示文摘Different sets of dry spell length such as complete series, monthlymaximum, seasonal maximum, and annual maximum are applied andmodeled with different probability distribution functions (such as GumbelMax, generalized extreme value, Log-Logistic, generalized logistic, inverseGaussian, Log-Pearson 3, generalized Pareto) to recognize in whichduration, dry spells cause drought. The drought situation and temporalanalysis in the North of Iraq region were done using the SPI index andby software of DrinC at a time scale of 3.6 and 12 months. Because ofapplicability, availability of data and the aim of the study, SPI is selectedto analyze the dry spells in this study. Based on the maximum length ofthe available statistical period, the statistics for the years 1980 to 2019were used from nine meteorological stations for analysis. The results of thestudy showed the severity of drought during the study period which relatedto dry spells. The results of this research confirm the variation of droughtoccurrence with varying degrees in different time and different dry spellscondition in Iraq. | Safieh Javadinejad David Hannah Stefan Krause Rebwar Dara Forough Jafary Mohsen Nasseri | 2021 | Research in Ecology2021，3，1： | 0 |
| 5 | Analysis of Gray Water Recycling by Reuse of Industrial Waste Water for Agricultural and Irrigation Purposes显示文摘Isfahan industrial province with its numerous industrial estates in its area and consequently the amount of wastewater produced by these settlements is very difficult to deal with.Therefore,the need for proper wastewater treatment and efficient management of industrial waste water from the industrial estates of this province should be seriously addressed and followed up by the authorities.The purpose of this study is the feasibility of reuse of wastewater from industrial settlements for agricultural and irrigation purposes.The present study is a descriptive cross-sectional study.In this study,the average values obtained from the sampling and the results of the experiments on waste water from the industrial waste water treatment plant in Isfahan,2017,have been used.Average values of BOD5,COD,TSS and so on were compared with the standards set by the Environmental Protection Agency and analyzed in Excel software.According to the results,the average values of COD,BOD5,TSS,SO4,pH and catalyst quality parameters were determined from wastewater effluents of 315,162,93,164(mg/L),8.3 and 32.5(NTU)respectively.The results of the study show that the average values of the quality parameters examined from the effluent of the treatment plant other than BOD5 and COD are within the standard range and the limit for agricultural and irrigation purposes,which may lead to undesirable environmental performance of these two parameters. | Safieh Javadinejad Rebwar Dara Masoud Hussein Hamed Mariwan Akram Hamah Saeed Forough Jafary | 2020 | Journal of Geographical Research2020，3，2： | 0 |
| 6 | Groundwater vulnerability assessment using a GIS-based DRASTIC method in the Erbil Dumpsite area (Kani Qirzhala), Central Erbil Basin, North Iraq显示文摘Groundwater vulnerability assessment is a crucial step in the efficient management of groundwater resources,especially in areas with intensive anthropogenic activities and groundwater pollution.In the present study,the DRASTIC method was applied using Geographic Information System(GIS)to delineate groundwater vulnerability zones in the Erbil Dumpsite area,Central Erbil Basin,North Iraq.Results showed that the area was classified into four vulnerability classes:Very low(16.97%),low(27.67%),moderate(36.55%)and high(18.81%).The southern,south-eastern and northern parts of the study area exhibited the highest vulnerability potential,while the central-northern,northern and north-western regions displayed the lowest vulnerability potential.Moreover,results of the single-parameter sensitivity analysis indicated that amongst the seven DRASTIC parameters,the unsaturated zone and the aquifer media were the most influencing parameters.In conclustion,the correlation of 25 nitrate concentration values with the final vulnerability map,assessed using the Pearson correlation coefficient,yielded a satisfactory result of R=0.72. | Masoud H Hamed Rebwar N Dara Marios C Kirlas | 2024 | Journal of Groundwater Science and Engineering2024，12，1： | 0 |
