WebApr 12, 2024 · Abstract. Fast glacier flow and dynamic instabilities, such as surges, are primarily caused by changes at the ice-bed interface, where basal slip and sediment deformation drive basal glacier motion. Determining subglacial conditions and their responses to hydraulic forcing (e.g. rainfall, surface melt) remains challenging due to the … WebJorge A. Ramírez 4 than surface runoff. Components of interflow are quick interflow, which contributes to direct runoff, and delayed interflow, which contributes to baseflow (e.g., Chow, 1964.) Groundwater runoff is the flow component contributed to the channel by groundwater. This process is extremely slow as compared to surface runoff. redbook perth https://melhorcodigo.com
