Modelling tools differ in the hydrological processes, or water balance elements, that they calculate individually, save, and allow users to export for further analyses.


Flux or storage Tool output and/or calculation approach
WRSM-Pitman
(Sami GW) 		SPATSIM-Pitman
(Hughes GW) 		ACRU4 SWAT2012 MIKE-SHE,

semi-distributed,
more conceptual

MIKE-SHE,

fully-distributed,
more physical

AET total Output no*
