Assessment of geological hazards in urban areas must integrate geospatial and temporal data, such as complex geology, highly irregular ground surface, fluctuations in pore-water pressure, surface displacements and environmental factors. Site investigation for geological hazard studies frequently produces surface maps, geological information from borehole data, laboratory test results and monito...
ناپایداری ،گسیختگی و به دنبال آن رانش در شیبها از جمله اصلی ترین حوادث ژئومورفولوژیکی است که فاکتورهای متعددی از جمله اقلیم،توپوگرافی ،خاک پوشش گیاهی، زمین شناسی ، تکتونیک وغیره در آن نقش دارندکه ارزیابی میزان تاثیر هر یک از عوامل موثر در این پدیده ژئومورفولوژیکی جهت تهیه نقشه ی پهنه بندی خطر زمین لغزش(geological hazards) بسیار مهم میباشد. امروزه اولین اقدام برای مدیریت بهینه تاسیسات مهندسی و...
Identification of high potential risk and susceptible zones for natural hazards of geological origin is one of the most important applications of advanced remote sensing technology in tropical environments. Yearly, several landslides occur during heavy monsoon rainfall in Kelantan river basin, Peninsular Malaysia, which are obviously connected to geological structures and topographical features...
The USGS Multihazards Project is working with numerous agencies to evaluate and plan for hazards and damages that could be caused by extreme winter storms impacting California. Atmospheric and hydrological aspects of a hypothetical storm scenario have been quantified as a basis for estimation of human, infrastructure, economic, and environmental impacts for emergency-preparedness and flood-plan...
Communicating information about geological and hydrological hazards relies on appropriately worded communications targeted at the needs of the audience. But what are these needs, and how does the geoscientist discern them? This paper adopts a psychological “mental models” approach to assess the public perception of the geological subsurface, presenting the results of attitudinal studies and sur...
In the last few years, terraced landscapes have been receiving renovated interest all over world (e [...]
Offshore geological hazards can occur in any marine domain or environment and represent a serious threat to society, the economy, environment. Seismicity, slope sedimentary instabilities, submarine volcanism, fluid flow processes, bottom currents are considered here because they most common hazardous processes; tsunamis also examined secondary hazard generated mostly by earthquakes, volcanic er...
