moreZayandeh Rood Basin, Iran is a basin with many environmental hazard threats. In last years, analysts have concentrated on building an extent of strategic responses to raise the ability of communities and businesses to control and meliorate from natural catastrophes. The experiment from each new tension adds further to the procedure of risk management. This article inspects how they belayed for, and recuperated from, the incident. Perhaps not astonishingly, it represents their exposures and absence of readiness for dealing with a risk of this dignity. Then again, it proves the resilience of real-world managers and their confidence on an aggregate experiment to operate their own improvement. In periods in which hazard management has been under drastic press to indicate effectiveness and cost-efficiency. These threats function in environmental disasters with terrible reaction such as damage of human properties, disruption to human livelihood activities and the bother imposed on economy. So, hazard management is essential for solution these repercussions. Moreover, multi-hazards are associated with desertification, earthquake, and aridity, similar any other nation, Iran is imperiled by many environmental risk menaces and such menaces can peak in environmental catastrophes with massive reactions such as loss of people's lives, destruction of national assets, an outage of a man-made building, dangers overhanging mass population, etc. In this case, the integrated approach uses the Arc GIS to create individual map layers that describe the spatial distribution of a parameter describing the intensity of the hazards. In this study, the intensity of the hazards threat is classified into 5 classes based on scale. In last years, increasing population and development of settlements and lifelines over perilous zones have mostly increased the effect of natural catastrophes both in industrialized and developing countries. The classes and range values include 'very high', 'high', 'moderate', 'low' and finally 'very low'. As the study area, the Zayandeh Rood Basin (Z.R.B) was selected into 10km grids. The parameters explain the hazard threats, their areal extents and densities, were determined for each grid. So, each layer map of a particular hazard and risk layer shows the spatial distribution of that particular hazard threat. In this research, each layer of the hazard threat and risk map was integrated using the Arc GIS integration analysis based on parameters. More importantly, the SWAT analysis shows the spatial distribution based on parameters of hazards and risk parameters in a grid cell, as well as showing the basin as the table whole that could result in efforts made to alleviate many hazards in the future. This approach in hazard management assessment would significantly contribute to any efforts associated to develop early warning systems incorporating hard and soft measures in a high-and very high-intensity hazard threat areas. This article evaluates some of the items relevant to the performance of diverse GIS conveniences with respect to terrain-related risks dominant in Isfahan, with specific reference to landslides
