Seasonal catchment memory of high mountain rivers in the Tibetan Plateau

H. Gu, Y. Xu, et al.

This research, conducted by Haiting Gu and colleagues, explores how rivers from the Tibetan Plateau impact water storage changes and catchment memory across eight basins in Asia. Discover how precipitation and temperature influence seasonal catchment memory and enhance streamflow forecasts and water management strategies.

Abstract
Rivers originating in the Tibetan Plateau are crucial to the population in Asia. This research proposes a model to estimate terrestrial water storage change (TWSC) and characterize catchment memory. Investigating eight basins, the study finds that seasonal catchment memory in precipitation-dominated basins is controlled by precipitation, while in non-precipitation-dominated basins, it's influenced by temperature. Longer influence time corresponds to longer domination time in precipitation-dominated basins. Quantifying catchment memory helps improve seasonal streamflow forecasts and water resource management.
