Landslides are a major geologic hazard with estimated tens of deaths and $1–2 billion in economic losses per year in the US alone. The island of Puerto Rico experiences one or two large events per year, often triggered in steeply sloped areas by prolonged and heavy rainfall. Identifying areas susceptible to landslides thus has great potential value for Puerto Rico and would allow better managem...
The landslides impose serious damages to the economy, environment and human throughout the world. Identification of areas susceptible to landslides is necessary to avoid risks. In This research for Landslide hazard zonation in sarkhoon karoon watershed have been used Shannon’s Entropy Index and Information Value Methods. For this purpose, at first, landslide locations were identified using...
Landslides are among the most damaging natural hazards in mountainous regions. In this study, landslide hazard zonation was conducted in the Baba Heydar Watershed using logistic statistical regression to determine landslide hazard areas. First, a landslide inventory map was prepared using aerial photograph interpretation and field surveys. Next, ten landslide conditioning factors including alti...
حوضه آبخیز سیاهرود در بخش رحمت آباد شهرستان رودبار گیلان قرار دارد. که مساحت این حوضه 110 کیلومتر مربع است. هدف از این تحقیق بررسی پتانسیل زمین لغزش و پهنه بندی آن به روش ahp در سطح حوضه می باشد که با استفاده از عکس هوایی، نقشه های زمین شناسی و توپوگرافی و پیمایش صحرایی پراکنش زمین لغزش ها در گستره ی مورد مطالعه مشخص می گردد. از این رو در این تحقیق نقشه های مربوط با استفاده از سیستم gis تهیه و ...
Introduction Geomorphological hazards posed as a potentially harmful phenomenon that most important ones are mass movements and landslides. The occurrence of natural hazards (including landslide) has imposed the serious impact on countries’ economic development, especially the third world countries. One of the most important tasks of applied Geomorphology, is to check the position and ...
Landslide as a global disaster causes great human and financial damages. Identification of landslide causes and zonation assist in instability control and construction projects siting. This study aimed to identify landslide causes and instability zonation in Ardal county, Chaharmahal va Bakhtiari province, Iran, using Analytical Hierarchy Process (AHP). Current landslides were delineated throug...
Identification of susceptible areas to landslide occurrence is one of the basic measures for reduction of the possible risk and hazard management. The main goal of this research is to compare the applicability of two statistical landslide hazard zonation models, valuing area accumulation and Analytical Hierarchy Process (AHP),in Ziarat Watershed, Gorgan, Golestan Province.In a review of previou...
Landslide is considered one of the greatest natural hazards that causes high damage direct or indirect financial every year. One of the areas prone to natural factors in the occurrence of this watershed and from the North Country. One of the occurs Susceptible areas in watershed vaz. Landslide hazard zonation map was prepared by using AHP and 6 certainly factor, landslide index, weight factor, ...
natural hazards are among destructive agents that annually take thousands of lives and impose devastating damages in iran. spotting such a high risk areas can help reducing the amount of their probable risk. a 1:500000 liquefaction and landslide hazard zonation map developed for the southern shoreline of the caspian sea. this geotechnical hazard map divides the study area to 15 hazard classes (...
the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...
