Abstract
Among the natural hazards, without a doubt, the flood is known as a natural disaster. In this research, Shannon entropy model was used to prepare a flood sensitivity map. First, 34 flood watersheds were selected from Firoozabad basin, and then these 34 points were classified into two groups. With 22 points, 65 percent of the points for training and modeling, and 12 points, 35 percent of the locations that were not used in modeling were used for validation. First, a map of the status of the floods was developed and Then, 10 factors, slope, tilt, lithology, land use, NDVI, SPI, TWI, altitudes, rainfall and distances from the river were selected as flood factors in Firoozabad basin. Prioritizing the effective factors in the occurrence of flood by Shannon entropy index showed that the NDVI layers (2.03), rainfall (0.00), distance from the river (1.89), SPI (385.1), elevation classes (999 (0/19), gradient with weight (0,932), lithology (478/0), TWI (379/0), and land use (280/0), respectively (0/184) have the highest and the least impact Flood events. Based on the results of the ROC curve, the predicted surface area under the curve with 35% of the validation data is equal (91.42%) and for the success rate with 65% of the equal education data (92.53%).

Abstract
Cities occupy vast areas. These fields are composed of different topographic and morphological units. As cities develop and expand, their dealings with various units of topography and geomorphology and related topics increase. Geomorphological units are always associated with the dynamism of the natural environment. Any action for the development of cities in some way intersects with the mentioned dynamism and detachment, and consequently with morphological phenomena. In this approach, if some necessary principles and points are not observed, the morphodynamic balance of the environment will be disturbed and the great dangers of most of the equipment and facilities of the city will be threatened. Sometimes the intensity of morphogenesis is so high that it produces irreversible results. The present study is descriptive-analytical in terms of purpose and in terms of data collection method and in the form of a survey or field in which the researcher has made a questionnaire. The purpose of this study is to investigate the role of roughness in coastal city planning using a comparison of AHP and AHP FUZZY hierarchical analysis in Noor city. In addition to the main goal, The results showed that in the early stages of the planning process, simple methods can be sufficient when identifying development options as a focal point. Under these circumstances, the choice of advanced and technologically advanced methods does not necessarily produce different results. However, when planning needs to identify the spatial extent of the desired development area, it would be ideal to consider the intersection area proposed by both methods

Abstract
Considering the recent challenges of urban and rural areas of the country, in the previous years, urban and rural areas of Iran will face uncertainties and major issues. The purpose of the land and the elimination of the challenges of urban and rural issues in the country in the future requires identifying these issues and planning to fix or decrease its effectiveness. Therefore, in this research, using a futuristic approach that has a qualitative-descriptive approach, the purpose of the research was investigated. To achieve this goal, first, with the use of research literature and library studies as well as the help of 70 experts in various fields, first major issues in urban and rural development and land were identified in the horizon of Iran 1420. Subsequently, with the method of qualitative analysis and experts, the strategic scenarios of the country was presented to resolve the challenges of the country in the 1420 horizon. The results of the study showed that the country's study in the horizon of Iran 1420 with sudden abrupt disorders and increased uncertainty alongside economic, social, political, environmental, demographic, geopolitical, climate change, cyberspace, increase inequalities And there will be no predicted and untreated threats. In this regard, 20 future scenarios were designed and designed to address the macro issues presented in the research, which are designed and designed to challenge current assumptions and important questions for the future of the country. These scenarios show a number of strategic considerations for how to prepare the country to meet the developing needs of urban and rural community in the horizon of the country of 1420 in the face of a very dynamic and uncertain future.
