Slope Stability Monitoring Using Space-borne Repeat- Pass Sar Interferometry
A variation of the landslide activity is expected according to the climate change in the Alps, especially in permafrost environment. Mountain areas are not very well controlled by monitoring systems due to the high costs. Therefore, satellite data and especially repeatpass SAR interferometric techniques are an important option for the monitoring. In our contribution differential SAR interferome...
متن کاملDetecting Landslide Activity by Sar Interferometry
Operational monitoring of slope instabilities by SAR Interferometry poses a number of challenges due to the limited spatial extent of the landslide areas and rainy conditions usually associated with mass movement events. In this work we present the results of the application of both conventional DInSAR techniques, and a point-by-point, multitemporal study of the long-term stability of selected ...
متن کاملFrictional velocity-weakening in landslides on Earth and on other planetary bodies.
One of the ultimate goals in landslide hazard assessment is to predict maximum landslide extension and velocity. Despite much work, the physical processes governing energy dissipation during these natural granular flows remain uncertain. Field observations show that large landslides travel over unexpectedly long distances, suggesting low dissipation. Numerical simulations of landslides require ...

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
An examination of seasonal deformation at the Portuguese Bend landslide, southern California, using radar interferometry
[1] The Portuguese Bend landslide, located on the Palos Verdes peninsula in southern California, is a slow‐moving landslide whose activity is closely tied to infiltration from rainfall. We use radar interferometry to constrain the seasonal kinematics of the landslide from 1995 to 2000. Traditional interferometric synthetic aperture radar methods estimate an average downslope displacement rate o...
