Tghyyraqlym simulated effects on water on resources and disaster management of large Karun Basin (The case study: Ahwaz)

Abstract
    Climate change is a complex volcanoes, atmosphere, oceans, and the percentage of greenhouse gases in the atmosphere is, Effects are mutual. These changes lead to changes in the water and air, changing the spatial and temporal distribution of water supply and quality of groundwater aquifers and a whole new trend in the causes of global climate. And precipitation type (solid or mab), surface currents, evaporation, Tba industrial revolution intensified the use of energy. Reports ‌of the intergovernmental panel on climate change, suggest that average global temperatures in 2100 could not reduce the rate of 1/1 to 6/4 °C increases, this phenomenon occurs a phenomenon called global warming and climate change will result from it, the water cycle and water resources systems can be a radical change. Karun large catchment area whit about 12 large dams have been built and being built with the potential to produce 20 thousand megawatts of power generation is very important. Thus, detection and consequences of climate change and climate change in this area is very important. In this study, using data from the atmospheric general circulation models(GCM) under the SRES emissions scenarios, rainfall and temperature changes in the period 2039-2010 for the stations as the stations or Iran’s Karun basin is large, is simulated. The average monthly temperature and precipitation data required in the course of the next series of models HadCM3 and CSIRO atmospheric general circulation models under scenarios A2 and B1 using proportional data provided by the base period and further investigated Dvz.h is. The results indicate increased temperature for both models, respectively, 8/1 and 2 degrees Celsius and a decrease in rainfall for the period 2039-2010 are 6 and 4 percent.
