from aPielke (1984), bGash and Stewart (1975), cMonteith (1975) and dSceicz and Long (1969)


NOTE: The vegetation heights listed in Table A.3 are sample values only. Those values may not be the representative, expected vegetation height-values of those vegetation/forest types.


Data from Lee (1980).


Soil and Groundwater Parameters



a Values in parentheses are standard deviations.
Data from Clapp and Hornberger (1978).
