Reviewing these changes and predicting urban growth through modelling can help environmental managers in making more informed decisions. The purpose of this research was to simulate the expansion of urbanization and also its prediction in the future using the SLEUTH model in Zanjan. In this study, Landsat and IRS images were used 2001, 2002, and 2003. Then, slope data, land use, exclusion, urban development, transportation, and landing were introduced to the Cygwin using the controlled classification method, to implement the SLEUTH model. The results of model prediction indicated a significant increase will happen in urban areas by 38.1% over the next 22 years. The results also showed that with SLEUTH model calibration, the projected growth has a high scattering coefficient, in which case topography limits the development and expansion of the City. In contrast, the coefficients of spread and slope of play with points of 96 and 94 have considerably grown, respectively. The conversion of these lands into urban areas will slow down from now until the next 22 years, and this further development will be achieved along with the main roads of the province, as well as the actual results of the current situation will be the evidence for that. The results of this study can provide further study opportunities for planners and decision makers to consider preventive and controlling factors into strategic decisions.

This paper studies the landslide vulnerability of Tabriz using visual and statistical evidence. The evaluation of landslide susceptibility was performed using the evidential belief function model (EBF) and the index of entropy. The environmental impact assessment of landslides was carried out using the Promethean II model in three environmental, economic, and social phases. Finally, a landslide strategy plan for decision-makers was developed. The results of the analysis using the EBF model showed that 89.81% of the total area of Tabriz is located in a direct landslide vulnerability zone. The output of the receiver operating characteristics (ROC) curve showed 83.3% accuracy of the EBF model. The impact assessment showed that for the environment, the geological criterion had an output weight of 0.396; for the economy, the road criterion had a weight of 0.477; and for the society, the commercial criterion had a weight of a 0.452; all were the most affected by landslides. The results of monitoring studies of the largest landslides in Tabriz in 1957, 1984, and 2020 showed approximately 41.65 m of land sliding over a period of 63 years. To our knowledge, this study is the first in the world to predict the environmental impact assessment and provide a strategy plan for Tabriz.

While some countries have started developing green building rating systems, some others are following the existing systems. Iran does not comply with any of the existing systems due to political reasons and does not utilize such a system officially. The purpose of this study is to add environmental water attitudes to Madad's Green Building Model, which was developed solely on the basis of environmental climatic factors. The model of each city is a function of its climatic and demographic conditions and is implemented on the basis of expert advice and AHP methodology. The results of the monetary valuation studies were used to improve the selection of indicators and to accurately define their weighting in the model. The indicators in the current study are to reduce runoff volume, water consumption, and the reuse of grey-water. The assessment results of the study area showed that only 11% of these green building capabilities had been used.

Therefore, monitoring and controlling mechanisms have been developed for urban construction activities. Accordingly, urban green building ranking systems have been established around the world. However, Iran does not have its own system, nor does it follow any existing system due to political relationship issues. Through conducting literature reviews, this study introduces a new method of regulating green buildings based on the temperature factor of local climates and the sequestration of carbon on green covers, besides integrating the results of monetary studies with judgments of experts in AHP technology to effectively reduce energy consumption and its consequences carbon dioxide (CO 2) emissions. Taking into consideration the varying climatic conditions of the country, a separate quantitative model of assessing and ranking buildings has been developed for each of 600 cities considered; in such a way that it minimizes climatic disadvantages. Finally, the criteria for a green building assessment were used for a single district in Tehran containing 1195 residential building; the assessment found that the studied buildings utilized only 26% of the building capabilities considered as "green".

In the first phase, a Landsat satellite image (2013) and digital elevation model (DEM) of the wetland were used to determine the areas vulnerable to the CSLR-induced flooding under four water level rise scenarios of 0.2 m, 0.6 m, 1 m, and 1.4 m. Then in the second phase, the possible effects of the CSLR on some market values of Anzali Wetland and the livelihood of the wetland-dependent communities were assessed based on the loss of agricultural and fishing products (as two main sources of livelihood for local people), as well as the loss of different land uses surrounding the wetland. According to the results, under the most optimistic CSLR scenario of 0.2 m, the wetland area will be expanded from 19,095 to 24,942 ha, while an expansion of 19,353 ha (from the current area of 19,095 ha to 38,448 ha) is expected under the most pessimistic CSLR scenario of 1.4 m. This will affect a minimum number of eight villages, including 4,518 inhabitants (under the CSLR scenario of 0.2 m) and a maximum number of 41 villages including 22,493 inhabitants (under the 1.4 CSLR scenario). These people will have to displace and move from their homes, which leads to several social ills. Depending on the severity of water level rise under various scenarios, 545, 646, 670, and 699 ha of the total area (790 ha) of fish ponds will be destructed, and total numbers of 70, 76, 83, and 93 units out of the 172 active industrial units are predicted to be inundated. In sum, the total loss values (damage to agriculture and fish farming) under the CSLR scenarios of 0.

Special analysis also attention was paid to population density for the construction of the land development priority map and using satellite image analysis to determine land use changes and analysis of geo-spatial information, because highly dense populated areas represent the highly important urban and industrial areas. While geo-information technology offers an opportunity to support flood management adequate geo-spatial information is a prerequisite for sustainable development, but many parts of the world lack adequate information on environmental resources. Such information providing, which serves as an important tool for decision-making in land use planning, can help provide effective information to natural disaster management. This paper develops a framework for flood control and begins with some general comments on the importance of land use planning and outlines some current environmental issues and then presenting environmental models to use in disaster management plan by using GIS and remote sensing results. Flood control is a complex problem that requires cooperation of many scientists in different fields. The article also discusses the role that geo-information and environmental planning and GIS and remote sensing technology play in disaster management control to reduce negative impacts of flood and present proper alternatives for developing of Gorganrood in the north of Iran. Advanced high-resolution sensor technology has provided immense scope to the decision makers for analysis of flood and damages details using GIS and remote sensing.

Research paper thumbnail of 3D Analysis and Investigation of Traffic Noise Impact from Hemmat Highway Located in Tehran on Buildings and Surrounding Areas

In this study, a 3D traffic noise simulation model is applied on a GIS system. Visualized noise levels are formulated by the proposed model for noise mapping on all surfaces of the buildings and surrounding ground in a 3D platform. The investigation shows that there is a high traffic noise impact on the foreground and front facades of buildings, rendering these areas unsuitable for residential purposes. The ground area by the sides of buildings and the building side panels receive a lower noise impact. Most of these areas are still not acceptable for residential and even commercial use, only the back yards and back panels, have the lowest traffic noise impact. It also shows that the building height is not an effective factor for reducing motorway noise on the upper part of the building. Finally, construction cantilever barriers with a height of seven meters, close to the outer edge of the highway was presented as an effective way to reduce noise within the allowable range of noise pollution for commercial and residential purposes.

Research paper thumbnail of Urban planning using environmental modeling and GIS/RS: A case study from Tehran

This article discusses how an urban development model can be created and used to apply environmental information in a wider context, with the help of geographic information system (GIS) technology and remote sensing (RS). The proposed model is illustrated through discussion of its potential application to Tehran, the capital city of Iran. We emphasize the complexity of the environment and how it affects the identification, analysis, assessment, and planning aspects of urban development. Tehran's District 22 The specific area we discuss is District 22 in northwestern Tehran. Like many cities throughout the world, Tehran is experiencing increasing land use pressures. Improper land use and poor land management policies have exacerbated the problem by ignoring the environmental limitations of the land and disregarding its vulnerability and fragility. GIS and RS Geographic information system technology is a c o m p u t e r-b a s e d tool that allows users to integrate and manage geographic data. GIS users can combine data from numerous sources and link them to maps of specific areas. With GIS, urban planners can quickly search, analyze, and manipulate data. Remote sensing refers to collection of data through devices that are situated some distance away from the location being studied. Remote sensing can be conducted by aircraft, satellite, or other means. Use of GIS and RS has been increasing during the past decades (Aronoff, 1991). Although these techniques now are being employed to identify natural resources and manage urban and environmental projects in Iran's major cities, the

Mega cities such as Tehran have critical issues by increasing the vehicles, fuel usage and urban area expansion. Hence, to have a clear view points on the pattern of CO concentration in Tehran, the data of 14 air quality concentration centers in a midterm period (2009 and 2012) are used. The main novelty of this research is using the third quartile (Q3) as the pollution indicator which leads to more accurate results based on the exposure pattern in a day. Additionally, by Spline interpolation model and using ArcGIS software the zoning maps to show the CO concentration in urban area are illustrated and discussed. Using Q3 instead of the mean values showed more accurate results due to the exposure patterns. Due to the results, the CO concentration shows a downward trend and the most changes are in the Western side of the city.

Research paper thumbnail of Spatial Analysis Approach in Revealing the Global Sinks of Atmosphere Carbon Dioxide through “Leave One Out” Method

Journal of Geographic Information System, 2014

Global warming and climate change are the most important ecological issues of our time. The most ... more Global warming and climate change are the most important ecological issues of our time. The most well-known factor in this phenomenon is the redundancy of carbon dioxide in the atmosphere. Over the past 50 years the amount of residual CO2 in the atmosphere has risen from 40% to 45%. Reducing CO2 redundancy requires precise knowledge of the gas sources and sinks throughout the atmosphere. Despite having a leading role in residual gas levels of atmosphere, the diagnosis and types of changes of absorbing carbon dioxide are very much in doubt. Atmospheric measurements of CO2 concentrations are highly precise and provide a reliable measure of increase of CO2 in the atmosphere every year but they do not lead to the location of sources and sinks. Studies about understanding CO2 cycles began mainly around 1990 and most of these studies have been focused on non-spatial analysis. By ignoring the spatial effects, an important property such as closeness (adjacent) has been disregarded. The emission sources of gas are stronger than their sink sources i.e., whenever a sink is adjacent to a strong emission source, the measurements will show a massive existence of CO2 gas in that region although there exists a fine CO2 gas sink at below. Using the global measurements of CO2 and applying spatial analysis approach to "Leave One Out" method, our studies reveal the most probable spots of CO2 sources and sinks and that Negev Desert in Middle East is a distinguished CO2 sink region.

Therefore, generally, it monitors only the indices which are defined for those functions. Furthermore, district-based development policy, and decentralization of governance, necessitate more local autonomy, which requires closer monitors of districts for being sure of its movements in the frame of urban developing plans. The advancement of technology has created the expectation that we can monitor all details of the metropolitan administrative processes and involve them in decision support systems for urban management. In this study, a web based SDSS prototype has been implemented to monitor the Tehran development plans progress at districts level. This interactive system presents a map of Tehran which indicates the realization of each component of the city master plan in different parts of town. The design of system lets all districts produce and support their own reporting maps, and it presents them in their dedicated place of city map by snapping all districts reports, when a city report arises. Also it elaborates the problem of implementing and proposes "cloud computing facilities" as a solution.

Therefore, monitoring and controlling mechanisms have been developed for urban construction activities. Accordingly, urban green building ranking systems have been established around the world. However, Iran does not have its own system, nor does it follow any existing system due to political relationship issues. Through conducting literature reviews, this study introduces a new method of regulating green buildings based on the temperature factor of local climates and the sequestration of carbon on green covers, besides integrating the results of monetary studies with judgments of experts in AHP technology to effectively reduce energy consumption and its consequences carbon dioxide (CO 2) emissions. Taking into consideration the varying climatic conditions of the country, a separate quantitative model of assessing and ranking buildings has been developed for each of 600 cities considered; in such a way that it minimizes climatic disadvantages. Finally, the criteria for a green building assessment were used for a single district in Tehran containing 1195 residential building; the assessment found that the studied buildings utilized only 26% of the building capabilities considered as "green".

Research paper thumbnail of A Quantitative Analysis of Socioeconomic Impacts of Sea Level Rise on the Anzali International Coastal Wetland

In the first phase, a Landsat satellite image (2013) and digital elevation model (DEM) of the wetland were used to determine the areas vulnerable to the CSLR-induced flooding under four water level rise scenarios of 0.2 m, 0.6 m, 1 m, and 1.4 m. Then in the second phase, the possible effects of the CSLR on some market values of Anzali Wetland and the livelihood of the wetland-dependent communities were assessed based on the loss of agricultural and fishing products (as two main sources of livelihood for local people), as well as the loss of different land uses surrounding the wetland. According to the results, under the most optimistic CSLR scenario of 0.2 m, the wetland area will be expanded from 19,095 to 24,942 ha, while an expansion of 19,353 ha (from the current area of 19,095 ha to 38,448 ha) is expected under the most pessimistic CSLR scenario of 1.4 m. This will affect a minimum number of eight villages, including 4,518 inhabitants (under the CSLR scenario of 0.2 m) and a maximum number of 41 villages including 22,493 inhabitants (under the 1.4 CSLR scenario). These people will have to displace and move from their homes, which leads to several social ills. Depending on the severity of water level rise under various scenarios, 545, 646, 670, and 699 ha of the total area (790 ha) of fish ponds will be destructed, and total numbers of 70, 76, 83, and 93 units out of the 172 active industrial units are predicted to be inundated. In sum, the total loss values (damage to agriculture and fish farming) under the CSLR scenarios of 0.

In this study, a 3D traffic noise simulation model is applied on a GIS system. Visualized noise levels are formulated by the proposed model for noise mapping on all surfaces of the buildings and surrounding ground in a 3D platform. The investigation shows that there is a high traffic noise impact on the foreground and front facades of buildings, rendering these areas unsuitable for residential purposes. The ground area by the sides of buildings and the building side panels receive a lower noise impact. Most of these areas are still not acceptable for residential and even commercial use, only the back yards and back panels, have the lowest traffic noise impact. It also shows that the building height is not an effective factor for reducing motorway noise on the upper part of the building. Finally, construction cantilever barriers with a height of seven meters, close to the outer edge of the highway was presented as an effective way to reduce noise within the allowable range of noise pollution for commercial and residential purposes.

This article discusses how an urban development model can be created and used to apply environmental information in a wider context, with the help of geographic information system (GIS) technology and remote sensing (RS). The proposed model is illustrated through discussion of its potential application to Tehran, the capital city of Iran. We emphasize the complexity of the environment and how it affects the identification, analysis, assessment, and planning aspects of urban development. Tehran's District 22 The specific area we discuss is District 22 in northwestern Tehran. Like many cities throughout the world, Tehran is experiencing increasing land use pressures. Improper land use and poor land management policies have exacerbated the problem by ignoring the environmental limitations of the land and disregarding its vulnerability and fragility. GIS and RS Geographic information system technology is a c o m p u t e r-b a s e d tool that allows users to integrate and manage geographic data. GIS users can combine data from numerous sources and link them to maps of specific areas. With GIS, urban planners can quickly search, analyze, and manipulate data. Remote sensing refers to collection of data through devices that are situated some distance away from the location being studied. Remote sensing can be conducted by aircraft, satellite, or other means. Use of GIS and RS has been increasing during the past decades (Aronoff, 1991). Although these techniques now are being employed to identify natural resources and manage urban and environmental projects in Iran's major cities, the

Mega cities such as Tehran have critical issues by increasing the vehicles, fuel usage and urban area expansion. Hence, to have a clear view points on the pattern of CO concentration in Tehran, the data of 14 air quality concentration centers in a midterm period (2009 and 2012) are used. The main novelty of this research is using the third quartile (Q3) as the pollution indicator which leads to more accurate results based on the exposure pattern in a day. Additionally, by Spline interpolation model and using ArcGIS software the zoning maps to show the CO concentration in urban area are illustrated and discussed. Using Q3 instead of the mean values showed more accurate results due to the exposure patterns. Due to the results, the CO concentration shows a downward trend and the most changes are in the Western side of the city.

Research paper thumbnail of Spatial Analysis Approach in Revealing the Global Sinks of Atmosphere Carbon Dioxide through “Leave One Out” Method

The most well-known factor in this phenomenon is the redundancy of carbon dioxide in the atmosphere. Over the past 50 years the amount of residual CO2 in the atmosphere has risen from 40% to 45%. Reducing CO2 redundancy requires precise knowledge of the gas sources and sinks throughout the atmosphere. Despite having a leading role in residual gas levels of atmosphere, the diagnosis and types of changes of absorbing carbon dioxide are very much in doubt. Atmospheric measurements of CO2 concentrations are highly precise and provide a reliable measure of increase of CO2 in the atmosphere every year but they do not lead to the location of sources and sinks. Studies about understanding CO2 cycles began mainly around 1990 and most of these studies have been focused on non-spatial analysis. By ignoring the spatial effects, an important property such as closeness (adjacent) has been disregarded. The emission sources of gas are stronger than their sink sources i.e., whenever a sink is adjacent to a strong emission source, the measurements will show a massive existence of CO2 gas in that region although there exists a fine CO2 gas sink at below. Using the global measurements of CO2 and applying spatial analysis approach to "Leave One Out" method, our studies reveal the most probable spots of CO2 sources and sinks and that Negev Desert in Middle East is a distinguished CO2 sink region.

Therefore, generally, it monitors only the indices which are defined for those functions. Furthermore, district-based development policy, and decentralization of governance, necessitate more local autonomy, which requires closer monitors of districts for being sure of its movements in the frame of urban developing plans. The advancement of technology has created the expectation that we can monitor all details of the metropolitan administrative processes and involve them in decision support systems for urban management. In this study, a web based SDSS prototype has been implemented to monitor the Tehran development plans progress at districts level. This interactive system presents a map of Tehran which indicates the realization of each component of the city master plan in different parts of town. The design of system lets all districts produce and support their own reporting maps, and it presents them in their dedicated place of city map by snapping all districts reports, when a city report arises. Also it elaborates the problem of implementing and proposes "cloud computing facilities" as a solution.
