Some Specific Methods About Selecting Dams' Address

摘要

In this article, we take the Kariba Dam as an example and analyze the number and location of new small dams in detail through Exponential estimation method and Gray Analytic Hierarchy Process. Then, we set up a model and put forward the concrete strategy of regulating water flow. We firstly make a simple analysis of the Zambian River Basin topographic map by Google maps and ARCGIS maps. Thenwe extract the data into MATLAB image analysis. Using MATLAB can help us carry out a preliminary screening along the basic conditions of water flow, height and slope. According to dam site location restrictions, weapply to the GAHP, take local people's opinions, topography, geology, environmental protection, climate, total investment cost and annual running cost as the evaluation index to conduct a comprehensive evaluation analysis on the previously selected regions. Finally, we can select several regions with the highest comprehensive evaluation index as the final address. And the resulting dam system will allow effective control of extreme conditions in parts of the Zambezi River Basin.
