Think more rain means more river water? Not necessarily
Some rivers are receiving more rain than before but have lower water flow, according to a study More rain and snow equals more water in rivers, right? Not necessarily. A new study shows that, despite receiving more rainfall than they used to, river water levels are falling because of changes in climate. Global heating is intensifying the hydrological cycle, making wet regions wetter and dry regions drier, but how is this affecting river flow? Researchers from the Pennsylvania State University, in the US, have analysed precipitation and river flow records in more than 10,000 rivers between 1951
