In recent times, many countries in the world have, in implementation of cadastral plans, produced new cadastral maps, and, based on multiple purposes, use the scale of 1: 1000, 1: 2000 and 1: 2500.

This technology includes mathematical equations that calculate estimates of the dependent variables of erosion (soil losses, production and sediment) as a function of independent variables (four main factors: climate, soil, topography, and type of use). The parameters in these equations include exponential powers and coefficients that determine or modify the values of the independent variables as part of mathematical calculations, some of which are empirical values prepared according to basic data, while others have physical definitions associated with erosion processes. Mathematical symbols and logical sequence are among other features of mathematical models. In general, erosion mathematical models include regression-derived models, characteristic models, and process models. In addition to empirical methods, several mathematical models are presented concerning erosion, in all of which mass conservation law or the continuity equation are used as the controlling equation. These models include the dynamic and static models, the weep model, GULTEM and EGEM model, each of which is related to a particular type of gully and is applicable in certain conditions. Undoubtedly, the models introduced in this paper can not be considered as comprehensive models without any probable defects. Therefore, it is suggested that according to the climatic, geological, geomorphological, and ... characteristics, a suitable model be determined for assessing the rate of gully erosion in each region.For more than half a century, soil erosion prediction and modeling technology has been used as a valuable tool in protective design, engineering plans and research development.

Later, with the development of technology of radio systems, and then the positioning satellites, routing became faster and more precise. The Global Positioning System was first created by the US Army in 1983, with an expense of $ 12 billion, and with launching the first satellite into space. This system has a variety of basic, manual and car models that have higher accuracy and cost, respectively. The system consists of three spatial, ground and user controls. The receivers will compare the time of sending the signal from the satellite with its receiving time and determine from the time difference the receiver's distance from the satellite. It is necessary to receive information from four satellites in order to find 3D coordinates. Availability in all hours of the day, any kind of weather conditions and ease of use are among the benefits of the system. Variants of this system include TRANSIT, GLONASS, SRARFIX and DORIS.

Thus, in order to counteract the process of destruction and the expansion of human destructive activities in the protected areas, there is a need for scientific knowledge, expert and capable groups and more research activities in this field, and this need remains in place. National parks, as one of the protected areas, are in fact highly valuable genetic reserves of plant and animal species in each country and in the world, and will be the main backbone for the restoration of nature. To save life on the Planet, resources must be used properly and controlled, and renewable resources must be given the opportunity to form again, so that they can be always used.

The points are the places at which sources are injected to lines or collected, for example, schools, terminals, reservoirs, and so on. Lines are connections in the network that connect the points. The purpose of this paper is to illustrate three major applications of network analysis in urban planning. Through network analysis, the best route, which is generally the closest route between two points, can be achieved to reduce travel costs. Or, it is possible to select the nearest center from among the rescue centers, in order to help the injured in shortest possible time, and to prevent further damage to life and property. Also, through allocation of resources, it is possible to make a more appropriate and rational planning for citizens' access to public services and realization of social justice.The concept of the network evokes the concept of system.

While Tehran can be developed as the focus of some of the future activities, such as higher education and advanced technology in the future, it should be gradually taken out of the position of the general center for all of the country's affairs. To this end, the focus of the growth of other issues can be transferred outside Tehran - in different cities, or at a new point.
2) Iran’s capital is facing various problems - from traffic, transportation and access to air pollution. These issues should be solved or at least partly healed by employing efficient managers and utilizing a variety of facilities - human resources and equipment and funds.
3) The geographical situation of Iran is such that its different regions have different climates. Having a metropolis like Tehran, which is practically the center of political, educational, industrial, health and medical care and business of the whole country, necessitates the displacement of large groups of people of the country to or from Tehran – or residing in there- for the sake of their activities development. With these conditions, it is better to have a few metropolitan areas, instead of a major metropolis.
4) The situation in Tehran in view of the fact that most of its recently developed parts are located in hazardous areas in terms of natural disasters - earthquakes and the vicinity of active faults, the floating domains and the possibility of landslide, instability and land subsidence, flood risk and its history in Tehran, The issue of surface and underground water and droughts for several decades or more - has gradually increased the risk of life in Tehran.<br /> The process of migration to Tehran has continued according to the latest data of Iran's statistics center. One of this issue’s results is the growth of slum dwelling, insecurity development - especially in the marginal areas of the city and new cities, delinquency and unemployment and other problems in Tehran. Multiculturalism in Tehran turns into cultural problems, instead of cultural development of Tehran.
5) With this condition, Tehran’s growth is practically accompanied by the destruction of spaces and urban fabric with house-garden identity. The Capital that has neither it’s old nor a modern identity, practically loses the qualification of being the Capital to a country with civilization and cultural history of Iran.
6) Air pollution in Tehran is such that, in particular in the cold season, it is associated with the unnoticed loss of life of our young and old countrymen and those with respiratory problems. I called these casualties to be unnoticed, because many of those whose lives are being shortened because of this crisis, neither themselves nor the others count them as casualties due to air pollution.<br /> Along with these challenges and other important reasons for the necessity of stopping the growth of Tehran, the simultaneous attempts to make it possible to live in it and the gradual transfer of part of the activities out of the province of Tehran, as well as the need to find options for a completely new capital - not an existing city that will eventually lead to a fate like Tehran - there are various issues raised by critics of this transfer, main ones of which are:<br /> 1) Many problems in Tehran are urgent. There is no time left to spend energy on other options. Any amount of energy should be allocated to improve the current situation in Tehran.<br /> Answer: This summing up was done about the city of Tehran after the end of the war with Iraq, whose consequent was of course the creation and development of urban and modern infrastructure, and simultaneously, unplanned urban development, sale of licenses for building extra floors, and management according to money and imbalanced urban development.
