Ar. Saleh et al., PERFORMANCE OF THE DRAINMOD-CREAMS MODEL WITH AN INCORPORATED NUTRIENT SUBMODEL, Transactions of the ASAE, 37(4), 1994, pp. 1109-1114
The CREAMS nutrients submodel and the modified DRAINMOD-CREAMS model w
ere applied to subsurface drained and nonsubsurface drained fields. Th
e CREAMS nutrient submodel overestimated the total nitrogen losses fro
m the subsurface drained and the nonsubsurface drained fields by 61 an
d 91%, respectively. The modified DRAINMOD-CREAMS model overestimated
the total nitrogen losses from the subsurface drained and the nonsubsu
rfaced drained fields by 36 and 40%, respectively. The modified DRAINM
OD-CREAMS model significantly improved the simulation of the nitrogen
losses from the subsurface drained and the nonsubsurface drained field
s by reducing the error by 25 and 51%, respectively.
