Our new paper “Constraining Dynamic Sediment-Discharge Relationships in Cold Environments: the Sediment-Availability-Transport (SAT) Model” has been published in WRR! See here

For the first time, we modelled the time-varying sediment availability in cold environments by integrating the factor of basin temeprature. It highlights three key points:

• Glacier-snow-permafrost melting elevates sediment availability by enlarging erodible landscapes and enhancing channel-slope connectivity
• SAT model is developed to simulate dynamic suspended sediment concentration- discharge relationships by integrating sediment availability coupled by thermal and fluvial processes
• SAT-model can robustly reproduce the long-term evolution, seasonality and various event-scale hysteresis of suspended sediment concentration for cold basins
