PREC  :	Precipitation (mm)
ET	  :	Evaporation (mm)
GWSOIL:	Water uptaken from groundwater to soil water (mm) -> same as GSOIL
IRR   :	Irriagtion water (mm)
RTN_FLOW: Return flow (mm)
IRR_GW: Irrigation infiltration to groundwater (mm)
ROFF  :	Total Runoff (include surface runoff and Water infiltration to Groundwater) ROFF = ROFF1 + ROFF2
DSiB  : Water storage change in Canopy/SiB Surface (snow etc.)/Soil layers (mm)
BAL = PREC - ET + GWSOIL + IRR -RTN_FLOW - IRR_GW - ROFF - DSiB
DIS   :	Dischare (mm) -> responsing to FOUTQ (10^6m^3)
AREA  : Area of the station control area (km^2)
