Trends and variability in snowmelt in China under climate change
网页Snowmelt is a major fresh water resource, and quantifying snowmelt and its variability under climate change is necessary for the planning and management of water resources. Spatiotemporal changes in snow properties in China have drawn wide attention in recent decades; however, country-wide assessments of snowmelt are lacking.
Streamflow seasonality in a snow-dwindling world | Nature

Climate change decisive for Asia’s snow meltwater supply
网页2021年6月24日 · Here we combine models with observations to show that regional snowmelt is a more important contributor to streamflow than glacier melt, that snowmelt magnitude and timing changed considerably...
Improved understanding of snowmelt runoff from the headwaters …
网页2019年4月1日 · As a crucial source of runoff in headwater regions, seasonal snowmelt plays an important role in ensuring water availability downstream, particularly during low flow periods. As the major constituent of China's water towers, the headwater region of the Yangtze River (HRYR) provides water to hundreds of millions of people downstream.

Snowmelt erosion: A review - ScienceDirect
网页2024年3月1日 · This paper reviewed the generation of snowmelt runoff, the characteristics of erosion and sediment yield during snowmelt, the snowmelt erosion mechanism, and the applications of snowmelt modeling. The published results of sediment yield driven from snowmelt runoff ranged from 1 to 300 t km −2 a −1 , with the largest value of 1114 t …
Snowmelt in nature
网页Snowmelt is the phase between crystalised solid and an energised liquid. Snowmelt combines elements of ice and water; occurring when energy, in the form of heat, begins to unlock an asset stored over the cooler months. It is a period of unlocking the latent, life-giving potential in the soil, river systems, and oceans.
