In this research, PMP for 13 climatology stations which are selected in karaj river basin is estimated with the method of Hershfield (1) and (2), the results are in order of 274 and 131.23m.m with considering of 40% run off, average daily flow would be estimated 550 m3/s , which in comparison with the Maximum daily flow in sierra (dam entrance) station with 20 years statistical period which is 154.57 m3/s it would be acceptable.

Urbanization and urban development with rapid population growth and increased industrial activity and followed by uncontrolled consumption of fossil fuels is causing air pollution than the pollution every year as diseases and respiratory diseases, cardiovascular diseases and prevalence of mental and following that financial losses to many shows. In this paper, the relationship between such as temperature, pressure, wind and precipitation and CO pollution with mortality from respiratory diseases in people under 12 years Tehran during 1387-1378 were studied. Using descriptive statistics and regression and correlation analysis of relationships mean daily and monthly deceased variables with respiratory illnesses were paid cold.The results show that between climatic elements such as temperature, pressure, wind and rain with the deceased due to respiratory diseases under 12 years of strong relationship and significant correlation exists. That means the cold months in reducing the temperature and pressure and subsequent increase of respiratory diseases is growing.Also, the wind and rain and daily mortality in children there is a significant correlation between respiratory disease and shows every wind and rainfall is higher than the amount of pollutants consequently child mortality will be less.

Hot springs Mine phenomena are specific geographic areas emerged find. Complex urban life increase being caused by this disease was a factor that has long caused citizens from natural treatments to reduce neurological disorders, fatigue, muscle aches and joint pains and ... Use one of these methods use hot springs have been. City of Ramsar beautiful cities in the north that leads الیه located West province, this city an important tourist attraction and infrastructure of the past. Geological structure of this city is such a place where creating a large number of mineral spa. Taken during the research that has been a descriptive way society views tourists sample the hot springs were used was evaluated and The result expression this is a great potential in the use of hot springs in Ramsar city to become one of the true poles of tourism there.

In this paper, we have used the meteorological data of Isfehan, Kashan, Shahreza, Khorobiabanak, Golpayegan and Nain stations. The purpose of this article is representing a simple method to calculate potential evapotranspiration and to compute the evapotranspirated amounts by statistical methods and effective climatic parameters in evaporation. In this method, it was used Multiple Regression and data of evaporation pan as a dependent variable and temperature, saturation deficit, wind speed and relative humidity factors as an independent variables. Then, it was estimated the potential evapotranspiration values for study stations by equation of five variables. So that, temperature, saturation deficit, wind speed and relative humidity, it is computable the evapotranspiration values. However, the Results of this method have a reasonable similarity with evaporated values of pan. For example, this correlation coefficient is reasonable about one percent in Isfehan station. In addition, the results of the Potential Evapotranspiration regionalization have suggested that the increase of the Evapotranspiration values from west to east and also north to south so that in east parts of province (Khorobiabanak and Nain station), this phenomenon reaches to its own pick because of decreasing vegetations and increasing temperature.

In this paper the role of geological formation Fars Group (Gachsaran, Mishan and Aghajari) on aquifer water quality Dehdasht West has been studied. Considering the characteristics of stratigraphy, permeability, susceptibility to erosion and hydrodynamic characteristics of this formation is observed in the western Dehdasht Dehdasht West lacks a suitable aquifer for agricultural development in this section. Dehdasht lands west of Agriculture are very fertile, but underground water resources for irrigation in this desert land with this is limited. In Western Deadest lack or limited and seasonal surface water resources, rural agricultural lands to make drinking water from underground (well mostly) world are, as 70% land water resources ground water irrigation, but are Due to geological conditions of quantity and quality of underground water resources is not conducive for agriculture.On this basis to achieve results from chemical analysis and classification of water in the western plains Deadest chemical results Canola water wells were used and then Volvos diagram was drawn to this desert aquifer. These results show that generally the area between ground water and high salinity level is too salty and dominant in terms of sodium adsorption ratio in the range of low waters and underground water resources generally in the class C 3 S 1 (high salinity with low sodium adsorption ratio) and C 4 S 1 (very high salinity with low sodium absorption ratio) are placed. Ground water lands west Deadest component is considered salty waters and groundwater in the area of agricultural use are limited. In this paper three factors of geology, physical properties and aquifer quality of its chemical structure has been examined.

Community market is a term which belongs to the Iranian Community two thousand and five hundred years ago, remains the language and culture into a language other nation in the world and the equivalent local exchange business with a marketing system is and Architectural Considerations Because of the history deformed the business value and heritage of Iranian civilization-is becoming more Islamic and role of the ideological beliefs of Iranian and Islamic architecture as a transcendent model of design space Commercial-Islamic components and elements unique location and cultural exchanges and economic and social ... in Iranian and Islamic countries, many West body will. That stability considerations as a symbol of community values, the centrality of economic responsibility and sustainable architecture manifested and systematization is transcendental and mystical.

Agriculture activity is the most important economic business in Malayer area. Accordingly the major occupation in Malayer is cultivation. Due to its mountainous location with the high altitude, it has severed climatic fluctuation. Farm crops in both quantity and qualities are affected by frigid temperature in Malayer area. So, in order to raise in both quantity and qualities of cultivation yield in this region the characteristic of the physical environment behavior is needed to be study in both aspects, theoretical and empirically. Estimating and prediction of frigid help to the farmers of that region to decrease the damage on time.This article is based on study and analysis of statistical data which bring about during 12 years (1994-2005) by Malayer Weather Station. Due to short period and insufficiency of statistical data which was available (only 12 years) for this research, so it is complemented by using Chebyshev Theorem and estimated the frigid days during (Aban & Azar) 22nd October until 20th of December totally 60 days and (Day, Bahman and Esfand) 21st December until 21st of March totally 90 days and (Farvardin) 23rd of March until 20th of April totally 31days through 3 decades. The results of this research are as follows:• The long intense frigid period was during (Day & Bahman) 21st December until 18th February which.• The moderate frigid period was (Azar and Esfand) 21st November till 20th December and 20th February till 20th of March.• The normal frigid but, uncertain and dangerous period for cultivation was (Farvardin & Aban) 20th March till 19th April and from 22nd October till 21st December.• None frigid period was found in the other months.

One of the most important social problem after world warII in developing country is rapid urbanization. In most of the developing country yearly growth urban population is among 5 untill 8 percent. This urban explosive grow and the slums are effect of the inside immigration from village to urban, that call in various place and various form like marginal, squatter, Illegal, Irregular, spontaneous, unauthorized, informal settlement.Our country (IRAN) like other developing country encounter with this problem. At present in most urban and industrial city like Arak city there are slums.These thesis investigate structural and cultural feature of slums (Bagh Khalaj district) that doing with document and surveying at first abstract of science literature (definitions, scores and feature) of slums in other country and Iran and then survey physical and humanly structure of Arak city.After that survey slums and especially Bagh Khalaj district (case study) in Arak city. At the end of thesis on the base of results and to point out strategy, limitations, facilities and problems and then present solutions.
