Hydro geomorphology is a branch of natural geography that deals with studying the shapes of ups-and-downs which are resulted from the function of the water and streams, especially the rivers. Recognizing and expressing the hydro geo morphological elements and their functions on the primary structural surface in the Kheir Abad basin and also providing some practical plans to recognize and manage the environment of the region are very important. This region is considered as a sub-region of the Zohreh River in Kohkiloyeh & Boyer Ahmad province and this river is a sub-basin of the Persian Gulf basin. The Kheir Abad River is located in the province of Kohkiloyeh & Boyer Ahmad in Gachsaran County (located in the northeastern part of the region) which is the only main streaming river of this region that originates from the various subordinate streams (often as the seasonal rivers) of the northern, northeastern, eastern and southern altitudes, and finally it reaches to the Zohreh River in Kohkiloyeh County. The followings are the purposes of the present study: analyzing the role of the hydro geo morph logical elements of the region regarding to capabilities and limitations of the natural prospects and landscapes, providing some suggestions and strategies and applications for the region in the framework of the capabilities and limitations to reasonably use the available resources. The present and applied method in this study includes a filed one that can be a suitable method to achieve investigative purposes and evaluate the hypotheses. Examining the physiographic, hydrological and hydro geo morphological elements, the geology, climatology, soil and flora and filed studies in the region with the help of determining and analyzing the influential elements in land-forming process, Geo morphological shapes which are present in the region and their developmental conditions reveal significant role of streams.

Today, the redaction of inequality resources and facilities is one of the most important criteria for sustainable development and social challenge in our country. One of the main necessities of the national sustainable development process is attention to regional characteristics by utilizing a collection of economical, social, and environmental indicators in order to optimally designate resources for various regions along with identifying these differences. This research intends to analyze the level of development in provinces of Iran. First, 13 economical, social and environmental indicators have been identified and related data has been gathered for 28 provinces in Iran. In order to provide a composite indicator the method of factor analysis has been utilized and composite indicators for the provinces have been calculated and categorized. According to this categorization Kohkiluye and Buyerahmad , Tehran and Semnan provinces have been ranked first to third, while Kordestan , Sistan and Baluchestan and Hamedan provinces are ranked among the last.

Migration and its consequences have been discussed as one of the major social issues in recent years in Iran. In all official censuses, East Azerbaijan Province has the most migrants and executive managers are faced with serious challenges. This paper has analyzed migration behavior in inside and outside of East Azerbaijan province in recent three decades. Research method is descriptive and analytical and the statistic society is East Azerbaijan province. The results show that there is a populous link between East Azerbaijan province with neighbor provinces and Tehran. The majority of whom arrive to the province are from Tehran, West Azerbaijan, Kurdistan and Khuzestan provinces that include more than 70% of migrants and the main sources for immigrants from the province are Tehran, West Azerbaijan, Qom, Ardebil and Khuzestan provinces that include more than 80%. Also the main sources of who migrate inside the province are Tabriz, Maragheh, Ahar and Marand cities that include more than 50% of total immigrants and the major destination for migrants are Tabriz, Maragheh, Marand and Bonab cities that include more than 66% of them. Result's analyses show that there is not a systematic population replacement and that population exchanging occurs with cities that have more facilities and offer better services.

In order to improve the performance of tourism development in a desert town like khour and Byabanak according to its potential, using appropriate strategies would be increasingly necessary. In this paper, after finding the strengths and weakness, opportunities and threats, besides analyzing the views of tourism experts, with using SWOT technique, the appropriate strategies are offered for optimal utilization .The results obtained from quantitative strategic planning show that strategy SO1, is the best strategy, and ST2and SO5 are respectively the second and the third. Finally after declaring the strategies, some suggestions have been presented to promote tourism qualitatively and quantitatively. Then By tourism development in this town we can acquire to Socio- economical development in this region.
