Hi,
I am using WEAP Model in glacierized watershed but not gettinh good relationship between simulated and observed discharge as in Feb and march simulated discharge is very much high than observed even if i change melting point of snow more than the temperature in feb and march still maximum snow melt in these months...what can i do regarding this? which parameters i can calibrate to get good correlation?
secondly, ice melt temperature is kept default ranging from -10 to 10 Celsius Is there any specific reason for this can this be increase?

Thanks
