Water resources management is faced with many limitations and dimensions in the course of transformation in its conditions and scope of action. Based on this, identify the factors affecting the sustainable management of water resources. It is considered an important measure for its optimal use. Therefore, in the present study, the effective factors on the sustainable management of water resources were investigated based on the farmers' point of view. This research is descriptive-analytical in nature. And in terms of purpose, it is practical. And the approach governing it is quantitative. The statistical community is formed by the household heads of agricultural lands in the central part of Ardabil County. in order to review the issue Seven indicators were used in the form of 72 items. Structural equation modeling (Smart PLS) was used to analyze the issue. A review of the findings shows the initial evaluation of the measurement model indicates the appropriateness of the model. The results of the model execution showed, that five factors had a factor loading of less than 0.5 and were removed from the list of factors. The results of running the model again showed that all the remaining 68 items had an effect rate higher than 0.5. The results of the structural model indicate the existence of a significant structural relationship between sustainability management and economic, social, productivity, technical, educational, and institutional effects. The index of the coefficient of square determination showed that this coefficient was estimated to be higher than the strong value of 0.26 for all research indicators. The coefficient of determination index for the economic index was estimated to be 0.299 less than other indices, and the productivity index was estimated to be 0.511 more than other indices. The results show that reviewing and revising the management perspectives of agricultural water resources and moving towards a cross-sectoral and collaborative perspective based on optimal management, which along with maintaining the economic, social, technical, educational, etc. dimensions, plays an essential role in providing sustainable management. It plays water resources.

Most of residential areas, population centers, and agricultural lands are located along the rivers and especially on the river terrace, which are affected by river dynamics, discharge changes, and flood hazards, bed fluctuations and meander variations. Therefore, it is necessary to study the behavior and pattern of meander movements of rivers in order to avoid potential hazards. The current research conducted in a reach of Gharehsou River in Ardebil province and the field measurements were done at adjacent to Anzab village to the Samian Bridge. In order to determine the pattern of this river, the Leopold Sinuosity Factor and the central angle calculated using Cornice method were used in this study. The results showed that the average of the Sinuosity Factor in the study area was 1.47, Which indicates the high ratio of river sinuosity. It also indicates the spatial variation of meanders evolution is not the same over the studied reach. The values of obtained Sinuosity factor using the employed methods showed that the %71.11 of meanders (32 meanders) with sinuosity factor of 1-1.5 belong to the category of low meander degree. While, the %17.78 of meanders (8 Meanders) had the sinuosity factor of 1.5-2. The remained 5 meanders (%11.11 of the identified meanders) had the sinuosity values greater than 2. This means that there are at least 5 meanders in the study area that are susceptible to becoming an oxbow-lake. Therefore, it is necessary to stabilize the stream banks and river bed of the study reach through structural management and engineering methods.

Tehran metropolitan authorities have always tried to develop the most efficient model for managing Tehran metropolitan affairs. Currently, the Tehran city management model is the council-city model, according to which people elect the members of the city council by direct vote, and the Tehran City Council elects the mayor. Over the past years, and considering that the institutions and organizations in charge of managing and providing urban services have in some cases suffered from parallel work or even inconsistencies in tasks, there is a need to develop a model for integrated urban management. In this article, descriptive-analytical method has been used. This article is practical in terms of the purpose of the study. The purpose of this article is to achieve a model for integrated management of Tehran metropolis. The statistical population of this study is Tehran urban management experts for which 34 people were selected as a sample. The data collection tools of this research are interviews and questionnaires and the data have been analyzed using paired comparison and TOPSIS methods. As a result of this research, according to the identified challenges and using TOPSIS method, the efficiency of the developed research model (with the proposed name of service desk) compared to the current model of Tehran urban management has been confirmed. Also, the most important result obtained from comparative studies is that in the studied metropolises, all matters of governance and urban management are always under the command of one institution and parallel work has been avoided, which should also be considered in Tehran.

The Ghezel Ozan basin in an area of 50000 KM2 is in the northwest of Iran. Recognition of variables like captivity and deviation of rivers, erosion and compact surfaces, the affects of old lakes by the reflected affects on 1:50000 scaled topographic maps of the region, are some of the points which is tried to find out the changes of Quaternary of the basin. Although Ghezel Ozan basin is ended to Caspian sea as an open basin, the geomorphologic and topographic evidences show that this basin became independent between two basins of Ghom and Orumiye after Pasadenian moves and also was multiple closed sub basins which the waters were moved to the central pits in each surface such as Bijar, Zanjan, Tarom, Yangi Kand and Miyane. The size of some of these pits is such huge so that could be visible in topographic maps by water network and marl sediments of their bed. On the other hand, some are very small and limited which follow the local topographic position or has shaped under the influence of the main processes of the time and has been destroyed by changes. The past topographic situation and the main processes of glaciers in cold Quaternary, has made different lakes near Ghale Chay River. Pari Lake is an obvious example. However nowadays it is irrigated by an artificial channel ramified by Ghale Chay River.

Spatial Analysis of Crimes at Different Hours of the Day, the Days of the Week, Month, and Seasons is an Effective Way to Control and Prevent Urban Crime. These analyzes give city management and other city safety officials, including law enforcement officials, the possibility to take preventive measures to eliminate or mitigate the effects of these factors in the city. The purpose of this study was to investigate the spatial analysis of theft crimes on a daily, weekly, monthly and seasonal basis in the 12th metropolitan area of Tehran. The research method in this article is descriptive-analytic. The comprehensive statistical data included the statistical blocks of 1390 in the neighborhoods of the 12th district of Tehran and the crimes related to theft in 2010. The most important statistical tests used are the Center-Medium and Oval-standard deviation tests, and from among the clustering tests, the nearest neighbor index is used to identify massive cores. The results of this study indicate that 446 crimes related to theft, Ferdowsi and Lalehzar neighborhoods, and Sa'di Baharestani have the most crimes and minorities in Kosar and Mokhtari. The pattern of distribution of crimes in the 12th region is clustered and the most important crustal focal points are formed at the intervals of the Shemiran, Iran, Baharestan - Saadi, Ferdowsi -Laleh Zar, Arg Pamenar, Imamzadeh Yahya and the Cascade. The spatial analysis of stealing crimes also suggests that the direction and extent of theft is different at different times of the day, weekdays, and on a monthly basis.

 The purpose of this study was to develop good governance indicators and criteria, evaluate good governance in integrated management of Kish, and provide strategies to promote integrated management of coastal areas with good governance approach. To accomplish these goals, firstly, by explaining the subject literature and reviewing the research background, an integrated coastal zone management model with a good governance approach was presented. The main criteria in this model are participation, legislation, accountability, accountability, central justice, transparency, efficiency and effectiveness, and community-centricity, each of which includes sub-criteria. Then, by using questionnaire and interviewing residents and experts, as well as by applying hierarchical analysis method, good governance status in integrated management of Kish was assessed. The final score of Kish by calculations was 2.53 (out of 5), indicating a relatively inadequate situation of good governance in Kish integrated management. Finally, solutions were presented to promote good governance in the integrated management of

River morphology holds significant importance in the fields of geomorphology and river management and engineering. The marginal sections of rivers have consistently undergone changes in their riverbeds due to various social and economic factors. The Dare Ourt River, located in the Ardabil province, represents a permanent river that has experienced frequent floods and alterations in its channel morphology in recent periods. In this study, the Dare Ourt river was thoroughly analyzed using the Rosegen model at levels one and two. To conduct this study effectively, detaied data such as 1:2000 river topographic maps, hydrometric data, and boundary conditions from the Ardabil Regional Water Authority were collected and utilized. Furthermore, the HEC-RAS hydrodynamic model was employed to extract the primary indices of the Rosegen model with greater accuracy. The outcomes revealed that the majority of the river sections exhibit a C6c type, characterized by an alluvial substrate. Additionally, other dominant types observed within the four examined ranges include B6c, E6b, F6, and D. Field visits also confirmed a transition in the river type from C to F within range 4, which presents challenges for the reconstruction and restoration of the river in type F. As a recommendation, it is advised to implement restrictions to prevent the river from transitioning into type F.
