This investigation of urban planning and design is the first problem-oriented study in this subject in the southeastern part of Iran. As demands for new town developments increase, the intensity and efficiency of urban planning and design must be improved. This in turn requires an increase in the professional knowledge and systematic nature of the analyses and syntheses. The discussions in the thesis include; ideological schools, socioeconomic analyses, natural resource utilization, and sustainable infrastructures. In the thesis, a set of related subjects are analyzed and evaluated with the aid of new academic and experimental methods aimed to recommend enhanced theoretical and working solutions and to prepare for sustainable urban planning and design in the southern Iran region.
