- static FlexModel.get_root_zone_balance(pe, ep, srmax=250.0, lp=0.25, ks=100.0, gamma=4.0, dt=1.0)#
Method to compute the water balance of the root zone reservoir.
pe (numpy.Array) – Effective precipitation flux in mm/d.
ep (numpy.Array) – Potential evaporation flux in mm/d.
srmax (float, optional) – Maximum storage capacity of the root zone.
lp (float, optional) – Parameter determining when actual evaporation equals potential.
ks (float, optional) – Saturated hydraulic conductivity in mm/d.
gamma (float, optional) – Parameter determining the nonlinearity of outflow / recharge.
dt (float, optional) – time step for the calculation of the recharge. Only dt=1 is possible now.
sr (numpy.Array) – Storage in the root zone reservoir.
r (numpy.Array) – Recharge flux in mm/d
ea (numpy.Array) – Evaporation flux in mm/d. Consists of transpiration and soil evaporation. Does not include interception evaporation.
q (numpy.Array) – surface runoff flux in mm/d.
pe (numpy.Array) – Incoming infiltration flux in mm/d.
If Numba is available, this method is significantly faster.
