SUB

File type

GIS

Subbasin number

MON

Year

AREAkm2

Area of the subbasin (km2).

PRECIPmm

Total amount of precipitation falling on the subbasin during time step (mm H2O)."

SNOMELTmm

Total amount of snow melt on the subbasin during time step (mm H2O)."

PETmm

Potential evapotranspiration from the subbasin during the time step (mm H2O)."

ETmm

Actual evapotranspiration from the subbasin during the time step (mm).

SWmm

Soil water content (mm). Amount of water in the soil profile at the end of the time period.

PERCmm

Water that percolates past the root zone during the time step (mm).

SURQmm

Surface runoff contribution to streamflow during time step (mm H2O).

GW_Qmm

Groundwater contribution to streamflow (mm). Water from the shallow aquifer that returns to the reach during the time step.

WYLDmm

Water yield (mm H2O). The net amount of water that leaves the subbasin and contributes to streamflow in the reach during the time step. (WYLD = SURQ + LATQ + GWQ – TLOSS – pond abstractions).

SYLDt/ha

Sediment yield (metric tons/ha). Sediment from the subbasin that is transported into the reach during the time step.

ORGNkg/ha

Organic N yield (kg N/ha). Organic nitrogen transported out of the subbasin and into the reach during the time step.

ORGPkg/ha

Organic P yield (kg P/ha). Organic phosphorus transported with sediment into the reach during the time step.

NSURQkg/ha

NO3 in surface runoff (kg N/ha). Nitrate transported by the surface runoff into the reach during the time step.

SOLPkg/ha

Soluble P yield (kg P/ha). Phosphorus that is transported by surface runoff into the reach during the time step.

SEDPkg/ha

Mineral P yield (kg P/ha). Mineral phosphorus attached to sediment that is transported by surface runoff into the reach during the time step.

LATQmm

Lateral flow contribution to streamflow in watershed for the day, month or year (mm).

LATNO3kg/ha

NO3-N in lateral flow (kg N/ha).

GWNO3kg/ha

NO3-N in ground flow (kg N/ha).

CHOLAmic/L

Concentration of chlorophyll-a for the day, month or year (mic/L).

CBODUmg/L

Carbonaceous biochemical oxygen demand of material transported during time step (mg O2/L).

DOXQmg/L

Amount of dissolved oxygen transported during time step (mg/L).

TNO3kg/ha

NO3-N in tile drain flow (kg N/ha).

RCH

Reach number for the subbasin.
