I have Run the model on daily basis for 1 year. I made use of Win-SRM User Manual for the support. Some of the screen-shots are available in my presentation.

Hello,

you can try the official SRM user manual from http://aces.nmsu.edu/pubs/research/weather_climate/SRMSpecRep100.pdf I find it very helpful.

Michala Jakubcová thanks very much!

Hows that 'S' is calculated ?

S= ratio of the snow covered area to the total area

Is that 'total area' means the whole area of basin or the area of each individual elevation zone ?

Either the total area is the total basin area or the total area of each individual elevation zone ?

For SRM, we calculate the snow cover for each elevation zone, so 'S' should be calculated for each elevation zone as:

S=Snow covered area in a zone / area of the zone

Your expert opinion is required, please.

If you are running zone wise, its zonal sca/zonal area. If you are running the model without using zones its total sca/ basin area.

As far as I understood, you are using zone wise calculation. You have to divide zonal SCA by Zonal area. Your value must be in fraction between 0 and 1 based in the seasonal snow variation.

How to efficiently include wind factor (e.g. wind speed, wind direction) in SRM simulations? I read that wind factor could represent an issue in terms of results, so how to overcome this problem in snowmelt runoff modeling using SRM?

Luca Mauri Temperatures, Pressure & Wind Speed, and Direction in the hydrological cycle are attributed to initial losses from the precipitation in terms of Evaporation, Transpiration, and sublimation. There is no separate provision in WinSRM to add these variables directly. It can be achieved through separate calculation of ET & Sublimation Losses and incorporate in Csn, & Cr Coefficients.

Arun Gunasekaran I used the SRM, and the NSE is -0.2. The annual high and low flows are not being estimated properly. I get almost a straight line for my estimated streamflow. Also, the computed streamflow is higher at the end of hydrologic year (June - September). I tried many different scenarios and parameters. Can you please tell me which parameter should I try to change next? Thank you!

You need to give proper units while running winsrm. Kindly ensure that you are giving only positive degree days. And unit of rainfall accepted in model is cm. Usually u get 0.4 to 0.5 nse while training model. You get higher accuracy on precise datasets. Otherwise negative values indicate error in data.

Arun Gunasekaran, thank you for kind answer!

Can you please take a look at this question?

Your help is appreciated!

SRM manual is available with stepwise step procedure, you can take help from it
