Idensification of geomorphological characteristics of Karst area which are formedmainly of soluble Carbonate stones such as limestone is form the point of view ofapplication are related to many human activities such as industry and agricultural dueto the water they provide for thoese activities. The Khaviz anticline which is located inthe province Khoozestan and in folded Zagros, is studied in this trend. This anticline isdivided by Marun river in two western and eastern parts. The gurpi formation (latecretaceous), pabdeh formation (Eocene), asmari limestone (oligomiocene) andquartaermary alluvial materials are exposed in this anticline. Tectonic movements havecrushed the anticline and caused joint systems and 24 faults. The present climate issemiarid. Despite this climate there are different forms of karst features such as Lapies(german, karren), Dolines, uvalas, and karst vallies. These forms seems to belong tothe paleokarst. Geological structure and conditions of lithologhy has controlled thelater evolution of karst features dominantly. Manuscript profile

Duo to the status quo and capability of eradication with respect to lithology,pedology and topography, the northern part of Khoroslu region has but an extremepotential of gully erosion regarding to mass movements such as slip, slide, etc. for itsunstable soil. Because of Soil erosion and degradation in this region a large amount ofcultivatable soil is in danger. Nevertheless it is of great significance to study andscrutinize the important factors in creation and development of gullies in the region.In evaluating the origin and features of gully creation and development the role oftopographic and morphogenesis elements is regarded. According to examinations onthe studied region, slope, height, difference and existing materials have been known asthe most important factors in gully creation and development. In this research 29active gullies regarding geomorphologic features are selected. Length, depth, widthand height of the gullies as well as the height of their slope is determined and the dataare analyzed by means of Excel Spss software. The result shows that 0.1% of thechanges in gullies is because of changes in length which compared to the heightchanges is less effective. So the increase in height raises the slope and the congestionof soil then the development of gullies is reduced. Finally the long and deep gullies inhigher slope areas are less common compared to lower slope. Manuscript profile

Ashkzar region in Yazd province has been subjecting to fissures on the ground sincethe last two decades.This has caused some damages to dwellers. The fissures haveaffected some previous landforms as nebkhas and dunes and have made up somegullies and depressions that they fill with water on rainfalls times. These fissures werecreated by subsidence. Statistics analysis such as Analysis of variance, Tukey –Kramer Analysis,and t-test, and also laboratory and field studies show that this landsubsidence was resulted from ground water overconsuming and then falling the watertable. The Subsidence rate is investigated through external coming up of pipes andBouwer (1978) method. According to, amount of subsidence obtained is estimated tobe about 62 cm from 1973 to 2001 Manuscript profile

Delta is one of the compressible forms of river alluvium which are formed at the shallow main drainage near the river banks. Suitable slope, fertile soil, availability of water supplies, and the considerable size of Polrud delta, has made it a convenient and suitable ground for human activities, and that its size may very and become larger or smaller, as a result of delta’s evolution, because of the main river’s path, and other water network changes. The outcome of this evolution can have a positive or negative effect on its inhabitant. With respect to the importance of the matter and according to the surveys done, this delta is situated and Alborz Zone and its geological events have had an affective role in its developments. In the Quaternary period, it was effected by glacial age and interglacial age eras and has followed its development’s path in the Holocen epoch ,in such a way that at the present, this delta has been formed by two topographic slopes, river banks and plain, at the shallow basin of polrud. Delta’s medium slope is less 1% and has a very wet climate, in such a way that in the spring, the maximum (54.39 percent) and in the summer, minimum (9.14 percent) sediment are deposited. This research has been carried out according to aerial photographs and satellite pictures at three time periods (1967, 1994, 2006), ground measurements, topographic maps, library references, with the use of descriptive and analytic methods. The outcomes from the researches showed that this delta is of advancing type and has been formed under the effect of old and new river processes, and also the wave functions and effects at present era; therefore, it can ranked as a modern deltas.     Manuscript profile

Geomorphologic Characteristics are base of study of natural resources in watershed basin. Because, these Characteristics are influenced by many factors such as climate, soil, hydrology, ecology, geology and so on. Doubtless, erosion features will develop with Geomorphologic Characteristics. In this research, effective factors on geomorphologic Characteristics and development of erosion features have analyzed using remote sensing data and GIS and with an integration method. In this way, boundary of basin was clipped using topography map in 1:50000 scales. Then, all layers such as geology, slope, and land use and land capability were digitized. An image of Land sat ETM+ taken in 2002 was also used to discretion of geomorphologic unit, Type and interpretation of erosion features. The results showed that, Geomorphologic features in the basin separated to mountains, hills and alluvial deposit base on height, slope and morph metric Characteristics. Totally, eight Geomorphologic fancies are recognized. Stone mass with deposited cover from mountain unit with regular slope (1_1_1) have 74 ha (45% from whole area). Also, a lot of surface erosion has developed like white scattered spots and without vegetable or few vegetable. To add natural factors, human factors such as livelihood and sheep keeper can effect on developed erosion features.   Manuscript profile

Abstract Background and Objective: Natural feature have a decisive effect on locating, growth, and physical development of cities. Natural phenomena sometimes act as positive factors and sometimes as negative and deterrent factors. The main objective of this study is to identify the geo-morphological features of Yazd city using the data envelopment analysis (DEA) model in order to determine the sustainability of the city. Method: To achieve these goals, the geo-morphological indicators affecting the growth of Yazd including elevation, slope, aspect, geology, morphology, and pedology (land units) over a 30-year period from 1984 to 2013 were identified. Then, using questionnaire, the importance of indicators in development of the city was specified. Moreover, the DEA model was designed to examine the efficiency of development of Yazd. Efficiency of the units was calculated by GAMS software. The most efficient units involved in development of Yazd were recognized using Anderson and Peterson model. Findings: According to the DEA model during the study period (1984-2013), development of about 16% of Yazd was found to be quite efficient. In other words, during the study period, the years 1985, 1986, 2005, 2009, and 2013 have always had 100% efficiency. The most efficient unit in Yazd, based on the geomorphology indicator, was observed in 1986. Since then, with the development of city mainly in southwest direction the efficiency has been declining. Conclusion: The results show that indicators of slope, piedmont plain sediments, urban areas are playing an important role in the development of Yazd city. Manuscript profile

Vulnerability assessment and vulnerability mapping, is an important strategy for management of karst water resources. Due to the geomorphology of developed karst in Dalahoo karst aquifers and in other natural conditions of the area, the spread of contamination in these karstic sources is rapid and extensive. Therefore, the purpose of this study was to provide a Dalahoo karstic aquifer vulnerability map in Kermanshah province against surface contamination using the COP model. According to the aforementioned approach, the COP method considers three factors to assess the resource vulnerability: Overlying layers (O), Concentration of flow (C) and Precipitation regime (P). After calculating three factors C, O, P and preparing their vulnerability map, these layers were multiplied and the final map of the vulnerability of the Dalaho karstic aquifer was calculated. The results show that 32.83%, 14.32%, 22.22%, 14.34% and 16.47% of the area are located in the very high, high, moderate, low and very low vulnerable zones and this classes have been 222.88, 97.2, 147.49, 97.38 and 11.82 km2 of this area, respectively. Also, the results of vulnerability classes and their area indicate that 69.2% of the total area are located in the very high, high and moderate vulnerabilities, which indicates the high vulnerability of Dalahoo aquifer to contamination. The very high vulnerability zone with 222.88 Km2, has the largest area of the region. Manuscript profile

Many varied attitudes exists about how the changes occur in the land-surface from the time William Davis’s researches to the latest researchers in the history of geomorphologic philosophy, and many different terms are used by scientists in order to observe their ideas related to geomorphic phenomena. The phenomenon of duality has been less seen in the geomorphology field. There exist some contradictory phenomena in nature, but further investigation can show their correlation clearly. Durability can be considered as a better dynamic entropy. In this research, radar interferometry technique has been used in Yazd-Bahadoran area, as well as through field and library studies, the amount of subsidence and uplifting has been investigated and the results have been compared with the other researchers' studies, which is a new concept in the literature of geomorphology under geo-duality. The study results indicate that the main reason for the subsidence was not to cut down the level of groundwater, and in this regard the tectonic movements play a significant role. Also, the study shows a significant relationship between subsidence in the Bahadoran plain and the collapse in adjacent heights in terms of duality or dichotomy. Manuscript profile

Natural processes, especially geomorphology, play an important role in locating, planning and developing cities. In the past, so far, we have tried to find the best place for geo-morphological and environmental conditions for the development and physical development of cities. In this research, the applied geomorphology and its role in the physical development of Semnan city using Geographic Information System (GIS) and multi-criteria analytical hierarchical analysis (AHP) techniques have been investigated. For this purpose, effective criteria such as height, gradient, gradient direction, lithology and distance from fault are used. Each of the criteria was evaluated according to expert judgment and using Expertchoice software, weighting and importance of each of them was determined. Finally, using the fuzzy logic and geographic information system combination method, and according to the analytical comparison, the appropriate zones of the current situation of the city and the geomorphology of the region based on the critical points with the appropriate areas derived from the hierarchical analysis and the g.i.s Took The results of this research indicate that the role of geomorphologic factors in the location of Semnan is much more effective than other environmental factors.Also, data analysis shows that the city of Semnan is exposed to various environmental factors. Several of these factors, such as literacy, are severely restricted and may in the future create inappropriate conditions for the occurrence of other environmental hazards. To this end, the extension of the city must follow the geomorphological processes Manuscript profile

The 7/3 Richter earthquake of November 2016 in Sarpol Zahab, in addition to the loss of life and property, left many geomorphic effects. In this research, an attempt is made to identify the complications and evaluate the volume of these changes. First, based on the topography, the study area was divided into two parts: mountains and plains, and then the geomorphic effects caused by the earthquake were identified and investigated using aerial photos and satellite images and field visits. Then, the map of the Geological and Mineral Exploration Organization of the country was digitized using the ARC GIS software, and the slope map was prepared from the digital elevation model in the ARC GIS software. These data were used to better display the effect of faults, terrain, formations, domain instabilities and the cause of geomorphic effects caused by earthquakes. The results showed that the presence of resistant layers of Asmari limestone on the Aghajari, Marni and Gachsaran sandstone formations and the weakness and erodibility of these formations cause many geomorphological effects caused by earthquakes such as slope instabilities (Landslides, rockfalls, Deposit flows), ruptures, liquefaction, fluctuations of the underground water level. In addition to the identification of geomorphological effects caused by earthquakes, their location and location in relation to other geological factors were mapped and the role of geomorphological effects in creating secondary hazards and the comparison of these effects in two topographical units of mountains and plains were investigated.

The increase in the world's population, the effects of climate change and lifestyle changes have put increasing pressure on water resources and have led to widespread water stress in many countries. An effective way to reduce and control the continuous degradation of groundwater quality is to understand spatial and temporal changes and identify the main sources of pollution. In this research, using the geostatistical method, temporal and spatial changes in the underground water resources of Izadkhasht basin were investigated in a period of 11 years, considering the factors of water quality change. In this regard, different interpolation methods were compared, and the kriging method with exponential variogram showed better results for water quality parameters. The results of these analyzes showed that the most important factors in the salinity of water and soil resources in the region are destructive formations in the basin. So that in the quality maps of water resources, all parameters showed an increase in three points. Manuscript profile

Most of the settlements of Guilan province have certain natural constraints in physical development. In terms of geomorphology, these centers, in their physical development, have problems such as earthquakes, groundwater surface condition, forward and backward on the shores of the sea, flood, range of motion, etc. In many environmental management issues and land use, the most important and useful help of geomorphologist is displaying shapes and surface effects on the geomorphology maps, since the establishment and creation of settlements, above all, depend on normal conditions (geology, topographic, soils, hydrology, climate) and geographic location. Therefore, geomorphologic phenomena have a significant impact on the emergence, formation, distribution, and physical development of urban and rural settlements.This article is part of a research project under the same title (Preparing Geomorphologic Map of the West of Guilan with 1:25000 scale) which was conducted by the author in the West part of Guilan province; the results show that geomorphologic phenomena have an important role in the physical expansion of the settlements in the West of the province, some of which are the Caspian coastal sand dunes, steel wetlands (South West Astara), the Marine barracks around Choubar and Haviq, Global faults of Astara, and alluvial materials of Lavandevil, Choubar, and Haviq rivers, and range of processes, create some problems for the physical development of the settlements of the research area. Research method is based on form and process analysis on 1:25000 topographic maps, geology 1:100,000, aerial photographs, and, finally, at some stages of field visits, all the data on the land was evaluated. It is hoped that this work will provide a basis so that it would be possible to prepare these maps in broad national coverage for all the provinces, and give the report to the administrative organizations Manuscript profile

The knowledge of erosion estimating is requisite for controlling soil erosion. The purpose of this research was estimating annual soil erosion using anatomical changes in exposed roots of Carpinus Orientalis in Hassan abad valley, Chaloos, Iran. For this purpose, we select eight Carpinus Orientalis trees as quite random and cut their exposed roots. Moreover the geographic coordinates of trees, the slope intensity and direction, altitude and percentage of vegetation has been written. Cross-sections of 20 µm were prepared using microtome and the first year of exposure by erosion was identified. We finally estimated the mean annual erosion.  The statistical relationship of the mean annual erosion with the percentage of the plant coverage, geographical aspects and slopes were investigated. The mean erosion of the study area has been estimated around 0.4 mm per year. There was positive relationship between annual erosion and slope density and negative relationship between the annual erosion and percentage of the plant coverage. The samples obtained in southern aspect showed higher annual erosions. We concluded that anatomical changes of exposed roots (Dendrogeomorphology) of Carpinus Orientalisare valuable tools to date erosion events, however, the responses of diverse species under different types of erosion remains to be studied in future.

Development and establishment of settlements in direct contact with the natural base and geomorphology effects. Because of the topography and geology of the study area has certain limitations in terms of localization and development of their human settlements. In order to reduce the risks of the South West province of Khorasan Razavi and modify future plans of development and human settlements, to assess the feasibility of the study area was investigated. After studies and library and a selection of appropriate measures, using phase logic models, and GIS software to help, areas prone to develop settlements were determined. In this study was to identify suitable areas for development and the creation of settlements in the study area based on Landform, from eleven parameters, slope, aspect, elevation, soil, land use, elevation, distance to fault, distance from the river, away from the road distance from settlements, geomorphology as independent variables in recognizing the potential and geomorphological constraints in the region were selected. Finally, after zoning based on phase model, the results showed that about 61 percent of the study area is located on the floors very poor and poor, which means unfavorable geomorphological conditions in this part of the study area to develop settlements are human. About 16.40% of the study area has average conditions for the development and creation of new human settlements respectively. And about 23 percent of the area under study geomorphological area of favorable conditions for construction activity and the construction of new residential areas are. Manuscript profile
