摘要: The results are summarized of an integrated investigation glacier geometry, ablation patterns, water balance, meltwater routing, hydrochemistry and suspended sediment yield. ultimate objective is to evaluate the assumptions lumped, two-component mixing models as descriptors hydrology, develop a semi-distributed physically based model alternative. study demonstrate that reconstruction probable subglacial drainage alignments can be achieved through combination terrain modelling on estimated potential surface dye tracing experiments. Recession curve analysis, evidence seasonal instability englacial electrical conductivities assumed in model, non-conservative behaviour chemistry presence sediment, evolution system all indicate alternative static hydrology necessary. presented this paper energy balance for melt which operates hourly time step accounts changing spatial distribution day shading patterns change, routing procedures transfer moulins basis gradients, then route reconstructed conduit systems using hydraulic sewer-flow procedure.
