Model Parameters

...

Model Parameters:

• M = {  V_O , y_W , x_W , x_G , y_W ,   x_J , J_W0 }  – totally7 constants 

...

• all constants are positive

Model fitting

...

Source data corrections:

• one time-array P_wf(t)

...

Default settings:  w_O = 0.5 ,  w_W  = 0.1,  w_G = 0.1 , w_P = 0.2 ,  w_f = 0.1

Model function

...

q_O^↑ = q_O1^↑ ‧ N^↑  |   q_O1^↑= J_O ‧ ( P - P_wf )

...

J_W = J_W0 + krw(d) ‧ x_J

J_G = R_s ‧ J_O
