regional assessment of climate change using statistical tests:case study of gorganroud-gharehsou basin

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Assessment of climatic parameters caused by climate change: A case study Kan Basin

Water resources restrictions along with uneven distribution of water in different parts of Iran, have caused Iran to be highly vulnerable to climate change impacts. During recent years, IPCC has developed GHG emission scenarios which can be used with AOGCMs to predict climatic status for the future. Herein this research, Hadcm3 was used to simulate climatic parameters for three different period...

Simulation of climate change in Iran during 2071-2100 using PRECIS regional climate modelling system

Parameters such as future precipitation, temperature, snowfall, and runoff were modeled using PRECIS regionalclimate modeling system in Iran with the horizontal resolutions of 0.44×0.44°C in latitude and longitude under SRESA2 and B2 scenarios. The dataset was based on HadAM3p during the periods of 1961-1990 and 2071-2100. Theoverall precipitation error of the model in the period of 1961-1990 w...

Assessment of impacts of future climate change on water resources of the Hulu Langat basin using the swat model

formation and evolution of regional organizations: the case study of the economic cooperation organization (eco)

abstract because of the many geopolitical, geo economical and geo strategically potentials and communicational capabilities of eco region, members can expand the convergence and the integration in base of this organization that have important impact on members development and expanding peace in international and regional level. based on quality analyzing of library findings and experts interv...

Regional climate change of the greater Zambezi River Basin: A hybrid assessment

Projections of regional changes in seasonal surface-air temperature and precipitation for the eastern and western Zambezi River Basin regions are presented. These projections are cast in a probabilistic context based on a numerical hybridization technique of the MIT Integrated Global System Model. Unconstrained emissions send the majority of outcomes in spring precipitation to a drying by 2050,...
