Urban growth management requires an efficient system which can identify and organize all important citizens' needs. As we know specific rules and regulations determine relations, interactions, levels of performance and position of each section and institution within such a system. These days, the legal aspects of urban growth management system cause many problems, especially in developing countries. In Iran, urban growth management faces several problems because of the complexities of the legal system in controlling the regulations. This paper aims to examine the advantages and disadvantages of the current urban growth management regulations in Iran. The methodology of the research is based on content analysis of the urban regulation and its evolution using existing documents. The results showed that there is an insufficient and weak autonomy of municipality vis-à-vis the state and its affiliated organizations; which itself is a part of obstacles of integrated management in the country.

Three proximity variables included access to, number of, and total area of NPOS, which were measured using geographic information systems in a large geographical area. Area-level socio-economic status (SES) was measured by considering income, education, and employment at the scale of census zones and categorized into quintiles. The results show that there are significant differences (without clear pattern) in access to and number of NPOS among SES quintiles in Tehran; however, there was no significant difference in total areas of NPOS across SES quintiles.

Many different spatial models are used world wide for urban facility site selection. The most common models such as fuzzy logic, regression, artificial neural network, index overlay and taxonomy which each has its advantages and weaknesses. Today urban authorities are eager to find the right ways to increase the efficiency of the urban facilities with less environmental cost. This paper tries to integrate some of the models to propose a new integrated model by using GIS. The intent here is to design a model which could be generalized to many developing world. The method is practiced by selecting an example like waste disposal to realize the model. The fuzzy logic and analytical hierarchy process (AHP) model were integrated with many socioeconomic and environmental factors to select the best location for the solid waste disposal with least negative environmental impact on urban areas. The results revealed that the multi criteria models have the potential to be generalized to the all cities of the world. Moreover the model used multi factors to evaluate the different alternatives to find the most appropriated option. The present model has a high accuracy than the traditional methods which are common in developing countries.

After the consistency and authenticity of data were confirmed, by means of daily mean discharge and a software called Technical Hydrology (TH), monthly hydrograph was sketched for total period of 1969-2000 in Kamarkhani station in Amameh watershed outlet. Then, different models were tested using the equation of sediment transport and considering hydrological, climatic and biological parameters such as hydrograph situation, classification of discharge rate and the time of flow measurement. In all models, the regression relationships between the rates of water and sediment discharges were established. To choose an optimized model, the sum of the error sum of squares index was used. According to the index, the least sum of squares shows the optimized model. The results showed that the common model in which only one equation is used as a sediment rating equation has the highest error in estimation of suspended sediment. But, a model in which the data are separated based on wet and dry months and classification of the discharge rates, has the lowest error sum of squares and is considered as the optimized model.
