Accuracy Assessment of GLM and FDA Models for Land Subsidence Susceptibility Mapping in Semnan Plain
The mechanism of land subsidence and soil deformation is the dissipation of the excess pore water pressure and the compaction of the soil skeleton under the effect of natural or man-made factors. Land subsidence has occurred in more of 300 plains of Iran, and Semnan Plain is one of the most important areas that face to this phenomenon. The aim of current research was land subsidence susceptibil...
متن کاملSpatial Simulation and Land-subsidence Susceptibility Mapping Using Maximum Entropy Model
The aim of this research is spatial Simulation and land subsidence susceptibility mapping using maximum entropy model in Jiroft and Anbarabad Townships. At first, land subsidence locations were recognized using extensive field surveys and subsequently the land subsidence distribution map was made in the geographic information system. Then, each of effective factors on land subsidence occurred i...
متن کاملTowards Global Mapping of the Earth’s Land Surface Composition
New “geoscience-tuned” remote sensing technologies are now available (e.g. satellite-borne multi-spectral ASTER and airborne HyMap imaging systems) or soon to be available (e.g. satellite hyperspectral Hyper-J and EnMap systems) for the resources (energy, minerals and soils) community. These imaging sensors have the potential to provide global information at high spatial resolution for baseline...
متن کاملModeling and zoning of land subsidence in the southwest of Tehran using artificial neural networks
The earth's surface, due to its natural conditions and its structure is always changing and reshaping. One of the created deformations is the land subsidence. This is the most dangerous events which can be seen in most urban areas especially in the agricultural plains today. This study aims at zoning land subsidence and recognition of geometrical factors in southwest of Tehran. To estimate and ...
متن کاملGlobal climate change and local land subsidence exacerbate inundation risk to the San Francisco Bay Area
The current global projections of future sea level rise are the basis for developing inundation hazard maps. However, contributions from spatially variable coastal subsidence have generally not been considered in these projections. We use synthetic aperture radar interferometric measurements and global navigation satellite system data to show subsidence rates of less than 2 mm/year along most o...
