| 1 | Is multi-hazard mapping effective in assessing natural hazards and integrated watershed management?显示文摘Natural hazards are often studied in isolation.However,there is a great need to examine hazards holistically to better manage the complex of threats found in any region.Many regions of the world have complex hazard landscapes wherein risk from individual and/or multiple extreme events is omnipresent.Extensive parts of Iran experience a complex array of natural hazards-floods,earthquakes,landslides,forest fires,subsidence,and drought.The effectiveness of risk mitigation is in part a function of whether the complex of hazards can be collectively considered,visualized,and evaluated.This study develops and tests individual and collective multihazard risk maps for floods,landslides,and forest fires to visualize the spatial distribution of risk in Fars Province,southern Iran.To do this,two well-known machine-learning algorithms-SVM and MARS-are used to predict the distribution of these events.Past floods,landslides,and forest fires were surveyed and mapped.The locations of occurrence of these events(individually and collectively) were randomly separated into training(70%) and testing(30%) data sets.The conditioning factors(for floods,landslides,and forest fires) employed to model the risk distributions are aspect,elevation,drainage density,distance from faults,geology,LULC,profile curvature,annual mean rainfall,plan curvature,distance from man-made residential structures,distance from nearest river,distance from nearest road,slope gradient,soil types,mean annual temperature,and TWI.The outputs of the two models were assessed using receiver-operating-characteristic(ROC) curves,true-skill statistics(TSS),and the correlation and deviance values from each models for each hazard.The areas-under-the-curves(AUC) for the MARS model prediction were 76.0%,91.2%,and 90.1% for floods,landslides,and forest fires,respectively.Similarly,the AUCs for the SVM model were 75.5%,89.0%,and 91.5%.The TSS reveals that the MARS model was better able to predict landslide risk,but was less able to predict flood-risk patterns and forest-fire risk.Finally,the combination of flood,forest fire,and landslide risk maps yielded a multi-hazard susceptibility map for the province.The better predictive model indicated that 52.3% of the province was at-risk for at least one of these hazards.This multi-hazard map may yield valuable insight for land-use planning,sustainable development of infrastructure,and also integrated watershed management in Fars Province. | Hamid Reza Pourghasemi Amiya Gayen Mohsen Edalat Mehrdad Zarafshar John P.Tiefenbacher | 2020 | Geoscience Frontiers2020，11，4： | 4 |
| 2 | Bio-ecology of malaria vectors in an endemic area,Southeast of Iran显示文摘Objective:To determine some bio-ecological aspects of malaria vectors in Jask County,where is targeted for malaria elimination in the national program.Methods:Mosquitoes were collected monthly during 2013-2014 using different collection methods.Subsequently,ELISA test was used to detect the human blood index of mosquitoes.The susceptibility status of Anopheles stephensi was evaluated against the diagnostic dosages of seven WHO recommended insecticides.Results:A total of 3 650 female and 4 736 Anopheles larvae were collected including Anopheles stephensi,Anopheles culicifacies s.l.,Anopheles dthali.Anopheles fluviatilis s.l.,Anopheles moghulensis and Anopheles turkhodi species.Anopheles stephensi was the dominant collected species on human baits and indoors with high rate of unfed and gravid specimens in internal and external window traps.Human blood index was calculated as 14.3%for this species.It was also found to be resistant to DDT and Dieldrin.Conclusions:The collected species had a wide range of habitats,and resting behaviors.With regarding to the presence of most important malaria vectors in Jask.control of the disease may be so complicated;as based on the weather condition it can be transmitted during the whole year,except for cold months.With this strong potential of transmission,existing population movements in the area may lead to imported cases of malaria and local outbreak(s).So,more specific studies on malaria vectors in high risk areas of Jask County are recommended. | Masoud Yeryan Hamid Rreza Basseri Ahamd Ali Hanafi-Bojd Ahmad Raeisi Hamideh Edalat Reza Safari | 2016 | Asian Pacific Journal of Tropical Medicine2016，9，1： | 2 |
| 3 | Cost consequence-based reliability analysis of bursting and buckling failure modes in subsea pipelines显示文摘Risk assessment is a fundamental activity to evaluate the integrity of pipeline systems during their life cycle,which allows pipeline operators to focus attention on integrity management activities in order to prevent and mitigate failure and maintain the design safety level.Risks for materials and contractor’s quality are a major source of concern about the integrity of pipelines and have a remarkable influence on the optimized balance between capital expenditure(CAPEX)and operation expenses(OPEX)in risk-based integrity management of pipeline.While other sources of risks to pipelines have been investigated thoroughly,the impacts of construction and material quality have not been well studied yet.This paper addresses the influence of construction accuracy/quality and corresponding uncertainties on the failure of submarine pipelines in the presence of corrosion.Corrosion-bursting and corrosion-buckling failure modes(which are addressed as ultimate limit states of subsea pipeline in DNV-OS-F101)are investigated in a reliability analysis to predict critical failure year of the pipe.Sensitivity analysis is also implemented to estimate the importance of parameters on failure probability using Monte Carlo Simulation(MCS).The results show a high sensitivity of failure probability to construction accuracy,which defines contractor quality. | Bahram Mehrafrooz Pedram Edalat Mojtaba Dyanati | 2019 | Journal of Ocean Engineering and Science2019，4，1： | 2 |
