Dear DSSAT users,

 I run two models and the water balance in
DSSAT looks higher (see table below). I am not able to justify why Transpiration + soil
evaporation + surface runoff + drainage + runoff exceeds the rainfall amount in
the DSSAT simulation? Does DSSAT simulation considered capillary rise or water
table effect?

Water balance parameters as simulated with DSSAT and
WOFOST models for a long duration maize cultivar (26 years simulation)              
Water balance parameters DSSAT WOFOST 
Transpiration  (mm) 402 256 
Soil evaporation (mm) 181 183 
Surface runoff (mm) 26 85 
Deep drainage (mm) 47 27 
Rainfall (mm) 540 540 
 
Thank you in advance for your clarity
