The Institute of Hydrophysics of GKSS Research Center is developing the tools and expertise required for both past reconstructions and future predictions of substance fluxes on a regional scale and over a period of several decades, and to evaluate their impacts to society. The goal is to build our capacity to compare between scenarios, be it scenarios of substance-emission regulations, economic...

Understanding the variations of streamflow of rivers is an important prerequisite for designing hydraulic structures as well as managing surface water resources in basins. An overview of the impact of climate change on the streamflow in the Hablehroud River, the main river of a semi-arid basin in north-central Iran, is provided. Using the LARS-WG statistical downscaling model, the outputs of Ha...

an increase in energy prices will decrease the fossil fuel consumption; on the other hand, the cost-push will encourage technology improvement for firms and households. these changes will affect the emission level.this paper studies the changes of yearly pollutant emissions after an energy price reform in iran. we apply a computable general equilibrium model which consists of 7 energy goods (el...

The importance of energy crisis and global warming necessitates presenting strategies in order to decrease the amount of emissions as well as fuel consumption in large and complex industries such as refineries and petrochemical industries. Generally, refinery steam networks are regarded as units which consume fuel enormously. In this paper, the steam network of Tehran Oil Refinery is considered...
