A conceptual precipitation–runoff model (HYCYMODEL) is used to simulate the
daily runoff from the 67% glacierized Lirung basin (16% of which is covered
by debris). The average thermal resistance of the debris cover of the Lrung
Glacier has been estimated from the surface temperature of the debris, which
was obtained from Landsat 5 (TM Band 6) images. This enabled calculation of
the melt rate of the debris-covered area of the glacier using meteorological
data collected at a nearby weather station. The calculated discharge results
are roughly compatible with the observed daily discharges.
