DRAINMOD Simulation of macropore flow at subsurface drained agricultural fields: Model modification and field testing

[Display omitted] •DRAINMOD model was modified to simulate macropore flow using an empirical approach.•Modeling macropore flow improved daily drainage prediction for a drained field with cracking soil.•Predicted macropore flow contributed about 15% of annual subsurface drainage.•Modeling macropore f...
