The Kariba dam, which is constructed to provide power to Zambia and Zimbabwe, has been damaged seriously over the years so that it is urgent to solve this problem. This paper provides three main methods to address the situation. I illustrate the feasibility of each option by considering its potential costs and benefits, and it turns out that the third option, removing the existing Kariba Dam and replacing it with a series of ten to twenty smaller dams along the Zambezi River, is the optimal

... tegy to resolve the problem of the damaged dam and provide abundant supply of electric energy to the residents living along the Zambezi River as well. Then, I obtain three channel segments which are suitable to construct dams by analyzing the geographical environment and culture factors along the Zambezi River. Based on this, I establish the Analytic Hierarchy Progress (AHP) Model to determine the proportion of dams in the picked channel segments, which is determined by three main criteria and each criterion is related to two or three sub-criterions. With these factors, we get a specific proportion to distribute the small dams.
