fetch3.initial_conditions.initial_conditions#

initial_conditions(cfg: ConfigParams, q_rain, zind)#

Calculate initial water potential conditions

Parameters:

  • cfg (dataclass) – model configuration

  • q_rain (np.ndarray) – array of rain data

  • zind (dataclass) – z index dataclass

Returns:

  • H_initial (np.ndarray) – initial values for water potential [Pa] over the concatenated z domain (soil, roots, xylem)

  • Head_bottom_H (np.ndarray) – water potential [Pa] for the bottom boundary. size is len(number of timesteps)
