Abstract

Phenomena such as changes in rainfall patterns, global warming, polar ice melting, floods, and untimely severe cold and heat waves in many parts of the world have become so severe and damaging that climate change has become a primary focus of atmospheric studies. To investigate the impacts of climate change on the thermal regime and discharge in the Helmand River Basin, long-term data of these parameters at various time intervals (annual, monthly, etc.) were obtained from hydro-meteorological stations in this river basin from 1979 to 2022. Due to the non-normal distribution of climatic data series, the non-parametric Mann-Kendall method was employed. The discharge analysis was conducted by comparing historical and recent data at key stations. Results indicate a significant increasing trend in the long-term average annual air temperature in the Helmand River basin, while discharge at most stations has experienced severe fluctuations.
