This issue has been studied in Takestan Qazvin. For illustrating the issue, theories of Michael Todaro, Edward Sapir, Benjamin Whorf and William Samner have been used. The research has been done according to library methods (documents) and field methods (special for questionnaires and measurement).In addition to confirming the questionnaire by the experienced faculties, its reliability has been obtained in accordance with Cornbrash’s Alpha coefficient by 82,2 percent and the SPSS software is used for analyzing and processing.

Abstract
So that the morphological and transverse changes of the Ghezelozan River have been evident in recent years and caused some problems. In this study, the detection of river side changes was carried out using satellite imagery of TM and OLI Landsat 5 and 8 in the period 1993 to 2013, during which an interval of 158 km from the Ghezelozan River, using the transect method evaluated. The channel duct was divided into 24 transects based on morphology and the process of change. The average migration rate of the Gezelozan River duct has been around 4.47 m / year over the past 20 years. The highest transhumance rate between 1993 and 2013, at 10.58 m / year, is related to transect 16, resulting in 52.51 hectares on the right bank of the river. Overall, the results show that during the period 1993 to 2013, close to 207.14 hectares was added to the right bank of the river and nearly 215.31 hectares from the right bank were decreased. Also, in this study, sinusoidal index was used to study the shape of the duct flat, based on which there are 15 sinusoidal transects.

Abstract
Return migration is a reaction to the attractiveness of rural areas. This type of migration can have many and varied effects on rural area reconstruction. The purpose of this study was to identify and analyze the effects of return migration on the reconstruction of rural settlements in Neyshabur. The research method is descriptive-analytic and a questionnaire based. In this study, 37 villages in Neyshabur that had returning migrants were surveyed. And 55 effects of returning migrants on rural areas reconstruction were identified, that the Cronbach's alpha coefficient of 0.942 indicates the optimal reliability of the research instrument. The indices were evaluated under three social dimensions with 18 indices (α = 0.925), economic with 21 indices (α = 0.891) and physical-environmental with 16 indices (α = 0.852). Exploratory factor analysis was used because t-test showed that there isn't significant difference between the three dimensions except social dimension. The results showed that 55 effects identified return migration can be classified as 14 main effects with 78.79% variance. Accordingly, 1- increasing cohesion and solidarity among residents with 25.21% of variance, 2- improving service and welfare infrastructure with10.52% of variance, 3- boosting rural economy with7% of variance, 4- activating of capacities with 5.4% of variance, 5- developing Non-farming activities with 5% variance are the most important effects of return migration on the reconstruction of rural settlements.
