Changes in temperature and precipitation and, accordingly, climate change along with the occurrence of hazards such as drought and flood have a great impact on the hydrological status of catchments. Therefore, it seems necessary to study the effects of climate change on water resources. In this study, the effect of climate change on the hydrological status of Hablehrood catchment was investigated. Temperature and precipitation changes were studied using minimum temperature, maximum temperature and precipitation data from 1996-2017 and using LARS-WG model, climate change of Hablehrood catchment using HadGEM2-ES model and 2.6 RCP, RCP4.5 and RCP8.5 scenarios were simulated in 2021 to 2050. Then, the hydrological condition of the basin runoff was simulated with the SWAT hydrological model. The results of the LARS model in the baseline period showed a complete agreement of the baseline period with a slight difference with the modeling data. It was also found that in the years 2021 to 2050, the temperature and precipitation have increased in almost all months. The results of the SWAT model also show an appropriate and acceptable correlation between the simulated data and the observed values of Hablehrood basin. In addition, it was found that the increase in rainfall in the catchment has led to an increase in surface runoff in the study area in the forecast period 2021-2050. Finally, the findings of this study showed that the LARS model for investigating the climate change of the basin and the SWAT model have a high capability in simulating the runoff of the basin.
