Background: The concept of allometry states that the relative rate of change of a system unit is a constant fraction of the relative rate of change of the entire system, or of another part of the system.This concept is stated as a nonlinear relationship and has been verified in a variety of natural systems.
Materials and Methods:The allometric relations in various phases of basin evolution in forms of static and dynamic models wasinvestigated.In order to study the dynamic allometry, a model consistingof two basins was developed.The evolution stages and the erosion changes caused by artificial rainfall and tectonic movements and also in static form (natural basins) were monitored.
Results: The existence of allometricrelations in drainage basins that are progressing toward the equilibrium (natural basins and basins affected by erosion) are significant and verifiable.This kind of relations do not exist in tectonic affected basins that were moving away from the equilibrium.
Conclusions:Allometric relations in drainage basins can define different states of system such as equilibrium. Moreover, any factor that causes the basin to move away from equilibrium needs to have an initial effect on basin relations to cause disorder in the system,and this change,in many cases,can be formulated or demonstrated by allometric model. Therefore the allometric equations could be considered an important tool in predicting the evolution of drainage basins and assessing their performance in the past and present.

ntroduction
Since about a century ago, Iranians have been careful in facing the social developments of other nations and the implementation of the "development" paradigm in Iran and third world countries. And gradually their thinking has reached a degree of maturity to start an official effort to replace this paradigm.
A review of Iran's social history from 100 years ago until now, clearly indicates that Iranians have continuously observed the social developments of other nations and with the coming of the Pahlavi period, they witnessed profound spatial changes in Iran.
These developments took an organized form especially during the second Pahlavi period, and many programs were prepared in the field of administrative organizations, buying satellites, establishing a nuclear power plant, building big dams, creating a modern army, etc. The implementation of these programs in several decades was followed by a national review of what had happened. The general understanding of the society based on the emotional wisdom of what had happened can be summarized in a few basic points.
What has happened is pushing Iran towards a country with mass consumption and leading to dependence on foreigners.
The class gap and the population of the poor have increased drastically every day.
Nomadism and muralism are in danger of extinction
Environmental vulnerability has become a serious problem
Iran's cultural and historical identity has been exposed to destruction and its major change has manifested as a fundamental attack )Crossing identity, history and security(.
Theoretical foundations and objectives:
This article followed a comparative logic and mostly analyzed the differences between the development and progress paradigms. Also to run the progress paradigm it is tried to benefit from the executive structures of the development paradigm
Methodology
In order to achieve the goals of this research, at first, the bases and foundations of the development paradigm (Rusto in America), the land use paradigm (the French and the Germans) and the regional foresight paradigm (the European Union) in terms of epistemology are investigated, and according to the definition of paradigm according to Cohen, the semantic variables of each paradigm are indexed. The semantic variables defined for each paradigm were:

• The Hometown  of paradigm

• The Doctrine of paradigm
• The goals of paradigm
• The final destination of paradigm
• The executive subsystems of paradigm
• The ideological contexts of paradigm

After recognizing each of the semantic indicators of the paradigms, the recognition of these semantic indicators was discussed in the paradigm of progress. This work was done based on the latest version of the Paradigm of Progress document at the Iranian Islamic Pattern Center. In the next step, to compare these paradigms with each other, “Nich method” was used to calculate their spatial distance. The degree of difference of each in the field of Hometown, Doctrine, and Goals was determined. This comparison has followed “Jeanette's method” of analysis.
Findings:
Investigations showed that the four paradigms in spatial planning have sometimes fundamental differences in terms of Hometown, Doctrine, and Goals. These differences in their Hometowns, Doctrines, and Goals are different from what is discussed in the progress paradigm of Iranian society, and therefore, a review of the theoretical foundations of social and spatial evolution in Iran requires a serious revision.
Conclusions:
For the implementation of any paradigm, three systems (scientific-philosophical, governance and cultural) are necessary Which can generally be summarized in the following cases:
Borrowing the executive organization of the "development" paradigm is one of the valuable experiences, the use of which can reduce the fifty-year period of the progress paradigm to one or two decades.
Certainly, the implementation of the progress paradigm cannot be implemented without having three systems of "governance", "scientific" and "cultural", and this is the most important achievement of the development review and international experiences of several decades in the development paradigm.
In the field of philosophical and scientific system, although the combination of the field knowledge and the university is a suitable combination, but the change in the content is necessary both in the field of knowledge and in the university. Iranian scientists and researchers in both areas should define indicators that can continuously and intelligently evaluate the paradigm elements and the extent to which they have been achieved.
In the realm of culture, the tricks and techniques of the evangelists are very rich and only updating them and their form of presentation should be adapted and updated according to the taste of today's societies. In this matter, the main axes of the norms of the progress paradigm should be placed in the agenda of the cultural trustees and help in all processes that can transform these norms into social behavior at various scales.

Investigation of the morphological evidences on the quaternary glacial of Iran has been of interest to many researches. However, the origin of such studies can be attributed to Domorgan (1890) and Bobek (1955). In the same vein, over the past ten years, Iranian researchers have conducted deeper studies on the changes in the climatic conditions of Iran in the quaternary. The analysis of the obtained climatic data currently registered in Iran, on one hand, and the existence of locations with remarkable differences in terms of temperature with adjacent regions, on the other, have attracted the attention of geomorphologists to such areas, as well as to their distribution in Iran. It is evident that, by focusing on the estimated environmental temperature, one can guess that these areas have also had greater temperature characteristics during the cold periods in the past relative to their adjacent regions. The regions which show greater temperature than their adjacent areas are called cold troughs. If the annual temperature of these cold troughs is less than 5˚c and their surfaces are flat, then we can formulate a hypothesis for the existence of ice capes. This paper aimed at identifing the cold troughs in Iran and investigating their geomorphic characteristics in order to find evidences on the possibility of the existence of previous ice caps in these areas. The results revealed, for the first time, the presence of ice caps evidence over Namdan Plain.
