WebFor practical purposes, the most important result of the FARSITE tests to date has been that spread rates for all fuel models tended to be over predicted by the Rothermel spread equation (Rothermel 1972). Sanderlin and Sunderson (1975) made a similar observation and ascribed the cause to problems relating wind speed to elliptical dimensions ...
