Initial Conditions
The user can set intial conitions via the variables for H_observed, H, or V.
If the user provides a value at t0 for
H_observed, this will be used as the initial elevation.Else if the user provides a value at t0 for
H, this will be used as the initial elevation.Else if the user provides a value at t0 for
V, this will be used as the initial elevation.
Both lookup tables h_from_v and v_from_h are required by the model for setting initial conditions.
