Modeling Seasonally Freezing Ground Conditions

摘要

A prototype catchment scale distributed snow melt model (SNOMO) is developed for areas experiencing seasonally freezing ground conditions. SNOMO is based on the energy budget approach and is designed to account for variation in slope aspect and slope angle. This report contains the background to the development of SNOMO as well as a code listing of the prototype model. Validation in the complete sense has yet to be undertaken, although data for this purpose was obtained from 2 field seasons at W3 Research Watershed in Vermont through collaboration with CRREL.
