Radar Interferometry for Monitoring Land Subsidence Due to Underground Water Extraction
The underground water extraction induced subsidence has the characteristics of slow rate, less predictable location and coverage. Over a long time period, the cumulated subsidence can be up to a few metres. This paper demonstrates the feasibility and capability of using conventional two-pass differential interferometric synthetic aperture radar (DInSAR) for monitoring the underground water extr...
متن کاملMonitoring of land subsidence due to overexploitation of groundwater using PS-InSAR in the region in hamadan proviance, Iran
Land subsidence is one of the environmental hazards that has been less well-regarded by human societies due to lower human casualties. However, the earth subsidence causes irreparable damage to the urban areas and adjacent plains over time. In this study, Permanent Scatterer (PS) method has been used to monitor land subsidence in the region in hamadan proviance and its adjacent plains in west o...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Assessment of radar interferometry performance for ground subsidence monitoring due to underground mining
This paper describes the results from the recently launched SAR satellites for the purpose of subsidence monitoring over underground coal mine sites in the state of New South Wales, Australia, using differential interferometric synthetic aperture radar (DInSAR) technique. The quality of the mine subsidence monitoring results is mainly constrained by noise due to the spatial and temporal decorre...
متن کاملMonitoring underground coal mining - induced subsidence
Monitoring of mine subsidence by means of classical methods such as optical levelling or Global Positioning System (GPS) surveys can reveal deformations with sub-millimetre to subcentimetre precision for localised areas. However, to provide data on a reasonably dense two-dimensional (2D) benchmark grid are costly and time-consuming for all but the smallest areas. Moreover, a regular re-survey o...
