  For a long time, water and hydroelectric power are relatively important
resources. Their rational distribution is closely related to regional
agriculture, industry, residents, etc. In this paper, we mainly study the
problem of allocation scheme for Glen Canyon Dam and Hoover Dam in the Colorado
River Basin. Taking into consideration of various factors, we build models to
achieve optimal scheduling. Firstly, we propose the Water Strategy Decision
Model, which can obtain different distribution methods for the different water
levels. Also, we connect the two dams in series to consider the coupling effect
between them and integrate this part into the main model. Secondly, we propose
three criteria of allocation for water and power generation, namely, economic,
social, and environmental benefits. Social benefits mainly include the minimum
shortage of water and electricity for agriculture, industry, and residents. For
this multi-objective plan, the model is solved using a multi-objective ant
colony genetic algorithm under the constraint of constant total water volume,
and finally, the current reservoir capacities of the two lakes are input to
derive the annual water supply to the five states. Thirdly, based on the
location and development characteristics of the five states, we obtain a water
scheduling model based on the priority of geographic-industry characteristics.
Fourthly, we can regard the model as a four-dimensional space of industrial,
agricultural, residential and power generation water demand. The partial
derivative calculation formula of multi-dimensional space can be used to obtain
the results. Finally, we analyze the sensitivity of the model, and it shows
that the model has strong adaptability and is easier to popularize. Moreover,
we discuss the advantages and disadvantages of the models.
