Integrating a geographic information system and multi-criteria decision making methods have been lead to provide spatial multi-criteria decision making methods. In this study, the spatial potential of flooding was determined based on analytic network process and analytic hierarchy process. At first, six factors of flooding were determined as criteria. The criteria were the slope, hill-slope asp...
Kashafrud Watershed Area is the part of the Great Plains Gharehghom in the northeastern province of Khorasan Razavi with area of 8996 square kilometers and considered the main drain Mashhad plain. to determine flooding potential of Kashafrud watershed used of modified SCS Method, the GIS system according to classification of map watershed and Tamab grade 4 in the digital elevation model, mappin...
introduction flood is a natural hazard that its occurrences can be observed more frequently in recent years. for better flood mitigation and control, it is needed to identify flood production factors and determine the high potential flood areas. hydrological model is a simplified representation of natural system and the rainfall-runoff model is one of the most frequently used events for flood s...
Extended abstract 1- Introduction Flood is one of the most complex and destructive natural phenomena that cause significant damage to agriculture, fisheries, housing, and infrastructure and significantly affects social and economic activities (Chang et al., 2008). The relationship between geomorphological and hydrological parameters makes it possible to predict floods in gauged basins and gen...
wild plant germplasm possesses useful adaptive strategies. wild plant species, for example, are resistant to biotic and abiotic stress and can be used for reforestation, agriculture, and horticulture. we surveyed the potential of wild pear to resist flooding. we looked at survival, growth, biomass, and several physiological variables. the rootstocks of wild pear are candidates for planting in o...
One of the important and effective factors in the destruction of natural resources is the flood phenomenon, identification of this phenomenon and effective parameters in flood occurrence in natural resources and catchment areas is necessary. The purpose of this study was to determine the flooding of sub-basins in Jafarabad basin in Ilam province. In this research, the Jafarabad basin in Ilam Pr...
Prior to the implementation of CO2 injection EOR projects, the screening evaluation of candidate reservoirs will promote the economic benefits of CO2 injection. Currently, a uniform screening method for CO2 miscible flooding does not exist. Based on more than 112 successfully implemented CO2 miscible flooding reservoirs, which was referred in 2010 Worldwide EOR Survey, and CO2 miscible flooding...

various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...
The maps of potential flooding areas can be the appropriate tool for urban planning in the future. In this research, potential flooding areas criteria viz. the urban land use, distance of river, elevation, slope and ground water level were considered. The weight of decision criteria were evaluated by paired comparison matrix. The final potential flooding map was divided to five different risk c...
