A decade of use in the region Asia Flood Network with training of partners Notes: 1 Volume / Area relationship is need to estimate initial conditions for Glacier Water-Equivalent (This could be constant (e.g. 1.36) or based on models, empirical relationships) 2 Utah Energy Balance (UEB) model - It will be run at 90m resolution / 6-hour time-step Will be run sub-basin by sub-basin (start with sub-basin with largest glacier contribution) 3 (i) snow over ice, (ii) ice, or (iii) debris over ice (IF albedo=snow-albedo THEN this is snow-over-ice, so the regular (snow-melt) UEB will be run. IF albedo=ice-albedo THEN the new( glacier-melt) UEB model component will be run) 4 Initial conditions for SWE will be estimated based on precipitation SWE 4 (daily maps)
