Abstract
In today's world, due to the pervasiveness of the Internet and electronic information, one of the tasks of urban management is to improve the quality of life of citizens, their access, and the optimal use of urban electronic services. These services can help improve the geographical situation of the city due to reducing the need for physical movement of citizens, reducing
traffic and pollution and increasing access to services.
However, if the urban management fails to use and implement this type of service properly, there will be a negative attitude towards e-services for citizens. The purpose of this research is to evaluate the impact of urban management performance on the quality of life and the behavioral intention to use urban electronic services with an emphasis on citizen satisfaction in Mashhad metropolis. In this research, through library studies, literature review and previous researches, 67 indicators (items) have been extracted and categorized in the form of 19 components. After calculating the statistical sample size of the research through Cochran's formula, 478 questionnaires were distributed among the citizens of Mashhad. Finally, the components were evaluated using structural equation modeling with partial in Smart PLS3 software. Findings indicate that the citizens of Mashhad are moderately satisfied with the components and study subjects. The results obtained from structural equations show that The "Communications" component with a path coefficient of 0.87 affects the performance of urban management and the "Work facilitation" component with a path coefficient of 0.841 affects citizens' satisfaction with electronic services. The performance of urban management with a path coefficient of 0.717 affects the citizens' satisfaction with electronic services. Also, these two factors affect the quality of life with 0.58 and 0.252, respectively, and satisfaction with electronic services affects behavioral intention with 0.757. The urban management of Mashhad can pay attention to the results obtained from this research to achieve a city with desirable and satisfactory electronic services.

Abstract
The subsidence phenomenon is considered one of the most frequent hazards occurring worldwide and imposing irreparable damages every year. This phenomenon affects the ground’s surface and its layers and causes the ground deformation. It can be referred to as a morphological phenomenon that is associated with the gradual sinking of the ground and the vertical movement of materials. Among the various methods used to study the land subsidence pattern, the Differential Interferometric Synthetic Aperture Radar (DInSAR) technique has provided more accurate results. Therefore, this technique was used to investigate the subsidence rate in Mashhad plain from 2003 to 2010 and the Envisat ASAR (C-band) and Sentinel-1 ASAR (C-band) satellite images were employed during the year 2019. The results show that the highest subsidence rate of about 44 cm occurred in Qasem Abad and Kalateh-ye Barfi lands from 2008 to 2010. A subsidence rate of about 37 cm was also observed in the same area from 2007 to 2009. The interpolation results using piezometer well statistics show a decrease in groundwater levels in this area and confirm the accuracy of the results.
