Find sthe maximal flow rate in a system with a pump and a canal. The flow through the pump is determined by the gradient from inner to outer water level and a pump function. The flow through the canal is determined by the gradient from the canal water level to the pump inner water level and a flow function. The inner water level is unknown and estimated within this function, but a lower limit can be set.

Parameters:

  • h_tide (np.ndarray) – the outer water level at the pump

  • h_store (np.ndarray) – the canal water level

  • h_min (int) – the lower boundary of the inner water level

  • pump_par (np.ndarray) – parameters of the pump function

  • channel_par (Tuple[float, float]) – parameters of the canal flow function

  • dh (int) – increment of inner water level estimation

  • wind_safe (int) – gradient from canal to inner water level, which is induced by wind and therefore not contributing to flow

  • gradmax (int) – maximum gradient from inner to outer water level, at which pumps shall run

Returns:

  • a_channel (np.ndarry) – the actual maximum flow through canal and pump

  • h_min (float) – the estimated inner water level

  • q_pump (float) – the maximum flow, which could be pumped if not limited by canals
