The climatic effects of rising CO2 levels will become increasingly significantin the future. Consumption estimated reserves fossil fuels in next two or three centuries add far more to atmosphere than has been emitted date unless ambitious conservation efforts technological innovations reduce influx. Atmospheric concentrations increase at least twice and possibly four times highest amounts measu...

River flow forecasting plays an important role in planning, management and operation of water resources. To achieve this goal and according to the phenomenon of global warming, it is necessary to simulate the daily time series of rainfall and runoff for future periods. Therefore, it is important to survey the detection of climate change event and its impact on precipitation and runoff in the ba...
