Effects ofclimate change onriverrunoffandprovide solutions toadapt toits effects(Case Study: BasinTuyserkanHamedan)
Abstract:   (2097 Views)

Climate change in addition to the direct impact on climate parameter, indirectly on the economy, society, agriculture and ...was impacted and will cause consequences such as floods, drought, migration, poverty and associated. Thus it is necessary to determine the mechanisms and more prepared to reduce the negative consequences of climate change phenomenon is essential to seems to be.Because of the importance of the climate change phenomenon on water resources in rivers, scrutiny of river behavior and specially river dischargein the future periods affected by climate change is essential to water resource management and finding solutions for adaptation and mitigation to climate change.Goal of this reaserch is investigation of climate change impact on watershed runoff of Tuyserkan river and appropriate solutions to reduce the impact of these changes.For this purpose, hydrometric and meteorological data and so soil characteristics and topography of the area, were collected.Using the soil moisture accounting algorithm was implemented to continuous rainfall-runoff model for sub basin of Tuyserkan plain upstream.Then using 15 general circulation model and LARS-WG model and using the beta distribution function were simulated rainfall under A1B and B1 scenarios.Rainfall-runoff model was run using futurerainfall amounts and volume of runoff in each of sub basinwas presented in the future period of 2011-2030.Finally, with 10% increase assuming ofrainfallbycloud seedingtechniquewas estimated toriverrunoff.The results showed thatthedecrease inrainfalldue toclimate changewillreducerunoff volumeof eachsub basin. Asof40.5millioncubic meters in base period will be to34.9 and 35.8 million cubic meters under scenarios A1B and B1. The results showed that the 10% increasein precipitationfromcloudsseeding, about 2millioncubic metersof runoffvolumedeclineddue to climate change will be compensated. The results showed that the 10% increase in precipitation from cloud seeding, about 2 million cubic meters of runoff volume declined due to climate change will be compensated.
