Figure out frost depth on a slope
Webin northern Ontario to predict frost depth [4]. The relationship between cumulative freezing degree days and frost depth was found to be as follows: FD=5.537 TI (3) Where: FD = Frost depth (cm) TI = ∑ (T Air, Mean + 5.31˚C) (C°. Days) T Air, Mean = Average daily air temperature (C°) Methodology The LTPP database was utilized in this research. http://conf.tac-atc.ca/english/resourcecentre/readingroom/conference/conf2008/docs/x1/soliman.pdf
