Interactive Calibration Program (ICP)

Parameter Summary -  Sacramento Soil Moisture Accounting Model:

Tension Water Capacities: UZTWM, LZTWM
Free Water Capacities: UZFWM, UZK, LZFSM, LZSK, LZFPM, LZPK, PREE, SIDE
Percolation: ZPERC, REXP
Impervious Runoff: PCTIM, ADIMP
Evapotranspiration: RIVA, PE Adjustment Curve

When using the ICP to calibrate the SAC SMA model, the parameters are adjusted to improve the functioning of the model.
When evaluating the hydrograph to determine what parameters should be adjusted, the following are general guidelines:

To adjust the
Recession flows - change LZPK, LZSK
Baseflow - LZPK, LZSK, LZFPM, LZFSM, PFREE, SIDE, RIVA, PCTIM
Percolation - LZFSM, ZPERC, REXP (primary)
LZFPM, LZTWM, UZFWM, LZSK (secondary)
Storm Runoff - UZFWM, UZK, ADIMP
Evaporation - UZTWM, LZTWM, PE adjustment curve
