Geo-tourism is the best practice tourism that sustains, or even enhances, the geographical character of a place, such as its culture, environment, heritage, and the well-being of its residents. Geo-tourism incorporates sustainability principles, but in addition to the do-no-harm ethic, geo-tourism focuses on the place as a whole. Desserts are now becoming a more and more popular tourist destination. Because of Iran's situation in a high-altitude plateau that surrounded by connected ranges of mountains, desert conditions is dominated in the interior plains. Some of the ecological features of the deserts in Iran are strong sunshine, relatively little humidity, little rainfall and excessive vaporization. This area due to Having special geomorphologic conditions, natural and unique landscapes and ... that apparent elements and components of desert, are important ecotourism areas in Iran. The goals of this study are identified geomorphologic and Geo-touristic attractions for development and introduction most effective parts of the region for focus tourism facilities.

Today, we have power to change the nature completely. This relates on the technological advances however in the case when we use the natural resource in non secure way, the environment will fall down soon. So what we called as a distortion of nature and environment are the results and products of the human wrong program and plans upon the land and environments. In the case of Lake Bakhtegan and Lake Tashk, building of many dams on the Kor & Sivan Rivers case to anarchy in the water catchment system.

Iran experienced an unprecedented cold air during January 1964 and 2005. The study of January-temperature's anomalies during 50 years since 1964 up to 2005 showed that the maximum anomaly occurred during Januaries of two years including January of 1964 and 2005. Negative anomaly causes to become-30 degree Celsius Minimum daily temperature during mention Januaries over Iran such as Saghez and Shahrkord stations.

Springs are one of the most important water resources that provide a part of human required water. Springs discharge study and their simulation is very important for water resources protection and planning. Karstification is highly influenced by precipitation and terrain, which can cause large differences in karst spring flow between different regions. Present research has been done to investigate the effective factor son karst springs discharge and to simulate springs discharge in the central Alborz highlands (Mazandaran Province, northern Iran).

Air transportation systems counted as one of the development ways of any area and more than other transportation systems communicates with weather conditions. Between various aerology phenomenon's, fog is one of the main reasons for cancellation, annulment and or flight deviation to other airports that don't take into consideration so far. In Ardabil airport, according to special topographic situation, necessary factors and condition is prepared for occurrence of fog phenomenon and for this reason, in more days of year and different hours of day, various kinds of dense fog forms.

Many researches done during the last twenty years has been detected a strong relationship between urban microclimate and precipitation. Urbanization is increasing in parallel with the increase in population. As a result of urbanization and population increase, the energy consumption has also been increasing due to heating, traffic and industrialization.

Extreme weather events are rare events from intensity and frequency perspective and at the time of their occurrence, ecosystem and human societies hardly can adapt themselves to occurred changes. Some examples of these events are Heat waves, Cold waves, Floods, Tropical cyclones, Tornadoes, Wildfires and Dust storms. Since extreme weather events occur when precipitation and temperature have extreme values, studying the extreme climatic data is a matter of vital importance. An important issue in the climatological studies is the identification of regions with the same climatic behavior. The results of regionalization based on extreme climatic events can aid decision-makers and planners in dealing with crises aroused from extreme weather events, especially in the development of management policies.

Iran has very complicated topography and climate including two mountain chains of Zagros and Elborz, two wide deserts of Kevir-e-lut and Dasht-e-kevir, forest lands and three large water bodies of Caspian Sea, Persian Gulf and Oman Sea. Climatically, Iran has a variable climate.Winters are cold with heavy snowfall in the northwest and below freezing temperatures during December and January.
