Masal district, like other parts of western of Guilan, is exposed to a number of natural hazards, including landslides due to its special conditions. In this study 91 identified landslides indicate the high importance of this phenomenon and its associated risks to the Masal. Therefore, the present study was based on a descriptive and analytical method, based on library studies and the use of existing documents and articles and researches previously done. Topographic maps with scale of 1.25000 and 1.50000 and maps Geology was used on a scale of 1.000.000. The GPS was used as research tool and Analytical Hierarchy Process (AHP) as algorithm. Data were analyzed in AutoCAD environment using ArcGIS software. In AHP method dual comparison of factors and components as the best zoning method was selected. Data were combined by using ArcGIS software and extraction of restriction and vector models and three-dimensional models such as DAM and TIN models. As a result of the work, not only in the hierarchical analysis method but also in the frequency of each of the factors, slopes of 10 to 30 degrees had the highest percentage of landslide.

The Impact of Climate Factors on Tourism Planning The importance of ICI is of great importance. In this project, the data of 10 stations of Meteorological and Sinopetic Province of Golestan in a 10- year statistical period (2003-2012) were collected by using the Turism climate index for assessing climate conditions. Data The defect was reconstructed through linear regression. In this system model, seven parameters, average monthly rainfall, mean temperature, mean relative humidity, maximum mean, relative humidity, daily average of sunshine hours and wind speed were evaluated. The purpose of this study was to study the climate conditions of the province of Gilan based on the TCI model and using the Geographic Information System (GIS) technique, a TCI map was prepared for all months of the year. Is. The results of this study showed that favorable conditions in this province are in terms of climate in May and is the most unfavorable month in terms of the tourism climate of the month of November, which has the lowest TCI. Geographically, the climate is ideal in the northern part of the province (including Talesh, Astara, Anzali, Kyashahr, Lahijan and Rudsar).

A particular challenge in terms of calculations is a hydraulic shock, accompanied by discontinuities of the flow. This phenomenon has not been fully studied, so the works of many scientists are devoted to experimental and theoretical studies of non-stationary processes with column separation of liquid. In this work it was defined the nonlinear heterogeneous model based on Geospatial Information System (GIS). By the way the process of modeling for unsteady fluid flow at drinking water transmission pipeline was presented.
