Doubt regarding snowmelt runoff

Open LSRathore opened this issue 6 years ago • 2 comments

We receive the total discharge at outlet using fortran code of routing model. That code uses runoff and baseflow to calculate the discharge. Does it acknowledge the runoff due to snowmelt or the runoff calculated by VIC is the total runoff by snow and rainfall?

Hi @lokendrarathore, per the VIC documentation you can output snow melt for a grid cell, the variable is OUT_SNOW_MELT. I believe that the snow melt is calculated separately from the surface runoff based on my understanding of the model, but I may be wrong....

Depending on your application (scientific question) and domain you may need to explicitly output the snow melt variable and use that for your routing. Should be a few changes to the code so very doable.

Please let me know if you have any questions or if I can help clarify anything further.

I just wanted to clarify that the discharge, calculated using lohmann routing model, considering OUT_RUNOFF and OUT_BASEFLOW is the total discharge. Or do I have to rout again with OUT_SNOW_MELT and OUT_BASEFLOW and then add it to the last discharge?
