A formulation method of two-parameter operating condition spectrum for intake water pump station is put forward. After water-level of the source river is selected as norm according to the required operating condition of the intake water pumping station, the joint probability distributions of water level and daily water demand are statistically determined to quantitatively define the variation and the margin of the working conditions for the pumping station. The models based on operating conditions spectrum are developed for optimal design of water pump station. The enumeration and Wolfe reduce...
