In order to meet the needs of modern flood control, according to the current situations of monitoring in the Yellow River, three type's remote sensing manners are carried out, i.e. flood remote sensing automatic monitoring; drought remote sensing monitoring; unpiloted aircraft remote sensing monitoring. The three methods offer supplements for data collecting and processing in the Yellow River. As...
As the largest in-land fresh water lake of China, Poyang Lake is also an important wetland in the world. However, the lake area, like the other lake areas of China, has being faced series of ecological and environmental problems and challenges, such as soil erosion, land desertification, drought and flooding disasters, farmland being soiled, pollution, invasive species, loss of biodiversity, and more...
The estimation of soil wetness variations is of considerable importance to improve the reliability of flood warning. In this paper, Polarization Ratio Variation Index (PRVI) is presented which, on the basis of long-term multi-temporal Special Sensor Microwave/Image (SSM/I) data, can monitor soil wetness variations at a large scale. Nearly 18-years long time series PRVI are calculated based on the...
River ice has a significant impact on the Yellow River, as it affects the discharge capacity, impact hydropower generation, causes flooding. In this article we use Landsat-7 ETM+ imagery to identify river ice on the Yellow River and propose a methodology of identification river ice to make use of higher spectral resolution of multi-spectral band data and higher spatial resolution of panchromatic band...
Remote sensing, combined with in situ surveying, is an effective tool for monitoring the tidal flats. Airborne light detection and ranging (LIDAR) or radar interferometry can be utilized to measure precisely the surface topographic change. However, neither the satellite-borne synthetic aperture radar (SAR) nor LIDAR is an effective way to obtain appropriate data on tidal flats, mainly because of the...
In case of emergencies over large areas satellite remote sensing data can become a crucial source of information for disaster management and response allowing the recognition and assessment of damages to populated areas and traffic infrastructure, the identification of focus areas, and an efficient coordination of rescue actions. On 12 May 2008, an earthquake of approximately 8.0 Ms (according to...
