Snowmelt Simulation

Hi,

I am interested in modelling a continuous snowfall/snowmelt RUNOFF simulation. Is anyone aware of any sites/references that exist on this subject?? I searched through the CHI site without any results.

I would like to first obtain a sample of a working simulation before starting so I can better understand the sensitivity of each parameter.

I tried setting up a test file of my own but I am rather sceptic of the results. The main reason is that in the output file, the echo of the snowmelt simulation parameters states that the melt coefficients are in (MM.H20/(HR-DEG F)) and that the base temperatures are in (DEG F). I have stated in the B1 card that this was a metric simulation.

The data I will be using is from Atmospheric Environment Services (AES) so I would like to use a metric simulation.

Also, if I want to perform continuous simulations with snowfall I understand I am required to input both the daily windspeed as well as the daily maximum and minimum temperatures. In reading the manual it appears that the meteorological data for the TEMPERATURE block must be in the form of NWS Tape Deck 3200 format (IFORM = 0). So, I guess I have to create a routine to combine both the daily max and min temp and the daily wind speed from the AES format and record them in the NWS Tape Deck 3200 format. Is this correct?

Thanks and Regards,
Jeff Arason.

Jeff,

We have two resources that would probably help you on your quest for papers on this topic, unfortunately there is a cost associated with each one:

1) The Stormwater Bibliographic database that comes bundled with PCSWMM '98 (see http://www.chi.on.ca/pcswmm.html for more info). This searchable database contains over 4500 stormwater management modeling references (3500 with full abstracts). Searching for the term "snowmelt" reveals 50 papers.

2) Our series of Stormwater and Urban Water Systems Modeling conference proceedings (held every February in Toronto). I can't remember off the top of my head if there are any papers related to your interest, however I'd be happy to check if you are interested.

Let me know if you want to follow up either of these leads.
Sincerely,
