Constraining Dynamic Sediment‐Discharge Relationships in Cold Environments: the Sediment‐Availability‐Transport (SAT) Model

Abstract Accelerated glacier-snow-permafrost erosion due to global warming amplifies the sediment availability in cold environments and affects the time-varying suspended sediment concentration (SSC) and discharge (Q) relationship. Here, the Sediment-Availability-Transport (SAT) model is proposed to simulate dynamic SSC-Q relationships by integrating the sediment availability coupled by thermal processes, fluvial processes and long-term storage exhaustion into […]
