2.1 Errata to ST -X-3 from April of 1994
ERRATUM
Page 19, Table 4: The No. of yrs. sampled by Springer and Van Wagner (1984) at Kapuskasing was 4.
Page 22: The title for the Fuel Type C-3 & C-4 portion of Figure 3 should read "...Mature and Immature Jack or Lodgepole Pine."
Pages 26 and 54: Equation 32 should have read
a = 140 x e (-33.5/PDF) (32)
Page 39, left-hand column, first full paragraph: The crown fraction burned for continuous crown fire should read " ≥ 0.9".
Page 40, right column, last paragraph: Line 8 should read "types (C-1, O-1, S-1, S-2, S-3, D-1 )".
Page 43 and 58: Equation 77 should be replaced by the appropriate rate of spread equation for the fuel type in question. The rate of spread equation would simply have the ISI term replaced by the BISI term to derive the back fire spread rate.
Page 44 (and the figure list on page 5): Figure 22 caption should read "Length-to-Breadth ratio of elliptically shaped fires as a function of wind speed for grass fuels (equations 80 and 81)".
Page 44 and 58: Equation 80 should read,
LB = 1.1 x WSV0.464 , WSV ≥ 1.0 (80)
Page 46, 59 and 61: The flank fire Rate of spread should be designated as FROS rather than FRS.
Page 53, middle of the page: Under the 'General Rate of Spread Equation' it should read:
C-1 to C-5, C-7, D-1 and S-1 to S-3
Page 58: Under Length-to-Breadth ratio" Open fuel types (O-1)” should read
"Grass fuel type (O-1 )".
