Impact of climate change on surface runoff: a case study of the Darabad River, northeast of Iran

Climate change is one of the major challenges affecting natural ecosystems and various aspects of human life. The effects of global warming on the hydrology and water cycle in nature are very serious, and the quantitative recognition of these effects creates more readiness to deal with its consequen...
