Functional forms of equations were derived for predicting 10-year periodic height increment of forest trees from height, diameter, diameter increment, and habitat type. Crown ratio was considered as an additional variable for prediction, but its...
Flame spread - - Mathematical models. ;<br> Wildfires - - Prevention and control - - Mathematical models.
Experimental evidence from 250 test fires confirms the general formulation of Rothermel's 1972 mathematical model for predicting fire spread in wildland fuels. Numerical coefficients are reevaluated for the empirical relations governed by fuel bed...
