Hello Naveed,

I’m not familiar with WaSIM but have worked with CRHM. I think the answer to your question depends on the specificities of the work you are doing (i.e., are you interested on surface hydrology in permafrost environments or investigating permafrost dynamics directly?). There are a couple papers where CRHM was used in permafrost environments (titles pasted below). There is also a large library of CRHM available at the Centre for Hydrology of the University of Saskatchewan (UofS), where CRHM is developed: https://www.usask.ca/hydrology/ListPubs.php. Many papers there deal with Artic landscapes and could help you find some more details. I’d suggest you contacting the modelling team at UofS and explain what you are trying to do. They would certainly steer you in the right direction.

I hope this helps,

Marcos

Hi Marcos,

First of all thanks for your detailed comment.

I have contacted with the developers of CRHM and they have provided me required information which was very helpful for me to select the most appropriate model for my research scope. As long as concern about my research work, i will mainly focus on the runoff generations under changing climate from the permafrost zones due to dynamics of the Active Layer Thickness (ALT). The CRHM is better to use in the cold environments have mainly covered with snow and CRHM is applicable to the tundra or other like this environments found in Arctic, Canada and Alaska's regions.

WaSiM model simulate the dynamics of the active layer thickness more better as compared to CRHM and also gave three dimentional variations in the soil temperatures.

Therefore after review some articles and some other literature, I finally selected WaSiM. I can use CRHM if I found that I have enough time to simulate using it as well. By comparing both the model's results, I will conclude the application efficiency as well as I will be able to write some good articles.

Thanks a lot for you precios time and detailed comment.

Regards

Naveed.
