Locating Large Water Pipelines Using Arc-GIS Software

Water Pipe Line are the lines that take water from different resources and transfer it to drinking needed nodes, industry or agriculture. Because of the intense shortage of water resources especially in the eastern and central reigns of our country, in the recent years some plans have been proposed for water transferring among basins. These projects not only have led to a lot of social conflict in the area that these project have been done but also causes some subversive acts along the pipe lines and dependent installation. So finding suitable location for pipe lines from the passive defense point of view will be very important. In this research a method for finding suitable location for great pipe lines according to different criteria such as privacy, access, military, economic, population, geology, geomorphology, climate and hydrology is introduced. Each criteria is classified to several subgroups. So all the subgroups are done quantification in software of Arc-GIS9.3. Then with super position of above layers, the planed area and high risk places are coloured and determinedon the map. The results shows that the route which has the best access and the least intersection with Faults, agricultural areas, rivers and gas pipe lines with 374 kilometers lengths are selected as the best options.
