GPS in the Tailings Dam Deformation Monitoring

Volcano Deformation Monitoring Using GPS

Volcanic eruptions are often very destructive events, having a massive impact on the natural and human environment. In order to mitigate the effect of volcanic hazards such as pyroclastic flows, lahars and tsunamis it is necessary to closely monitor volcanoes. Ground surface deformation is recognised as a reliable indicator of an impending eruption and can give clues to magmatic processes at de...

Floods from tailings dam failures.

This paper compiles the available information on historic tailings dam failures with the purpose to establish simple correlations between tailings ponds geometric parameters (e.g., dam height, tailings volume) and the hydraulic characteristics of floods resulting from released tailings. Following the collapse of a mining waste dam, only a part of tailings and polluted water stored at the dam is...

The Application of GPS To Dam Surface Monitoring

Dam monitoring relies on the long-term measurement of small structural motions at regular intervals. Traditional surveying techniques and geotechnical instrumentation can effectively monitor oneor twodimensional modes of motion. However, spatial distribution of geotechnical instrumentation is usually limited to the locations that the instruments can be installed during dam construction, whilst ...

Dam Deformation Monitoring Data Analysis Using Space-Time Kalman Filter

Abstract: Noise filtering, data predicting, and unmonitored data interpolating are important to dam deformation data analysis. However, traditional methods generally process single point monitoring data separately, without considering the spatial correlation between points. In this paper, the Space-Time Kalman Filter (STKF), a dynamic spatio-temporal filtering model, is used as a spatio-tempora...
