Dear Sajad, in the following article you can find information for what you want to do, they use the MODIS snow cover product (MOD10) and a SRTM DEM.

Ünal Şorman, Using MODIS snow cover maps in modeling snowmelt runoff process in the eastern part of Turkey, Remote Sensing of Environment, Volume 97, Issue 2, 30 July 2005, Pages 216-230, ISSN 0034-4257, http://dx.doi.org/10.1016/j.rse.2005.03.013.

Hope it helps!

thank you for helping dear Andrés Santamaría-Artigas

Hi dear Sajad

Do you want model for Specific location or any location?

For specific location i think you need ground truth data in several time and several place of your location and for a general model for any location you should study features and events happened before snowmelt runoff.

I suggest study this papers to you.

My best regards

B.Salman
