Nasuh, Known as Matrakci was a miniature painter who accompanied King Suleایمان Kanuni during his campaign to Iran in 940-42 AH/1533-36 AD and he has drawn many miniature from lots of Iranian cities including Khoy, Tabriz, Zanjan, Soltaniyeh, حامدan, and Ghasre Shirin to Baghdad and Shahre Zur, Baneh, Bukan, Maraghe. Being capital during one part of the Safavid dynasty and in the other part as the second most important political, economical, social, cultural and architectural city in Iran, Tabriz was considered a very important city. Unfortunately, the natural and artificial disasters such as incessant earthquakes and war with the powerful neighboring countries like ottoman had destroyed many parts of its structure. Therefore drawn miniature from Tabriz is the most comprehensive visual documents of one of the powerful city of Iran in Safavid Era that it’s reviewing helps a lot to recognition lost elements of this city in the 16th century.

Security is one of the most critical factors affecting the quality of urban spaces. Nowadays, most of these spaces have become merely pathways with neither social life nor sense of belonging to it. Insufficiency of public surveillance along with weak sense of control and surveillance results in spaces with high crime rate. In the late 60s and early 70s, high crime statistics in open urban spaces around America and Europe, forced many city planners to provide physical and cultural solutions for it. Sensitive environmental design can simultaneously prevent the occurrence of crime and increase the control and surveillance over the public spaces. The main purpose of this paper is to achieve the most critical factors enhancing safe urban spaces. The research method is descriptive analysis and is done by comparative study on three outstanding theorists’ point of view toward the subject. Research findings identify that crime prevention is largely achieved through applying territoriality, surveillance and social interaction factors in environmental design.

Unsustainable growth of cities and creation a set of contiguous impervious surfaces have result on disorder of natural cycle of water in urban environments. This situation causes flooding and problems due it, pollution of groundwater resources and degrade the quality of the urban landscape by increase the speed, volume and frequency period of runoffs. conventional methods about the stormwater management have failed to demonstrate their effectiveness in this field. Thus, in recent years a new topic are created in the field of urban design that known as "water sensitive urban design". Water Sensitive Urban Design (short: WSUD) is the interdisciplinary cooperation of water management, infrastructer engineering, urban design, and landscape designing. WSUD develops integrative strategies for ecological, economical, social, and cultural sustainability. The purpose of Water Sensitive Urban Design is to combine the demands of sustainable stormwater management with the demands of urban designing, and thus bringing the urban water cycle closer to a natural one. This approach attempts to increase urban sustainability indicators, improve the quality of urban landscape and urban space amenities by offer operational mechanisms in relation to urban design and it attempts not only to close the urban water cycle in its natural cycle and achieve technical goals, but gain optimal utilization of runoff and change the vision of the issue from a threat to a valuable opportunity.The following is a description of some essential methods for sustainable stormwater management. These methods are grouped according to their primary function: water reuse, treatment, detention and infiltration, conveyance, and evapotranspiration. Here is the techniques of water sensitive urban design about stormwater management and link them to urban design concepts, till through that some methods to be introduced that they are more efficient than conventional stormwater management methods about performance, helping to complete the natural cycle of water, environmental sustainability of cities and urban design aspects.
