Flood disasters are one of the most serious meteorological in China. With rapid development information technology, individual monitoring tools could not meet need for flood disaster monitoring. Therefore, a new integrated air-space-ground method, based on combined satellite remote sensing, unmanned aerial vehicle sensing and field measurement has been proposed to monitor assess caused by dam failure Poyang County, Jiangxi Province. In this paper, an investigation system, general flooded...
Although it is well established that natural disasters of all kinds give rise to poverty, and poverty deteriorates the disaster loss, few studies have empirically proposed a comprehensive framework break down vicious circle. Our study alleviation policy with governmental accountability can socio-economic development, facilitate implementation risk reduction policy. Focusing on Great Western Development (GWD) policy, our conducted an index used regression discontinuity design explore effect...
A suitable calibration sample set is extremely important to acquire an accurate spectral-based model for estimating soil organic matter (SOM). However, unrepresentative was frequently collected due the inappropriate samplings pattern caused by problematic transportation logistics and complex geographic conditions, which resulted in fairly poor generalization low accuracy of spectroscopic model. Thus, we hypothesized that a dataset equivalent natural samples could be prepared under controlled...
Landslides can result in extensive casualties and huge economic losses. The accurate discrimination of the main slip direction deformation trajectory is an important prerequisite for studying landslide formation mechanisms designing control schemes. In process evolution over time, also changes dynamically provides a comprehensive reflection displacement state. However, few studies on this topic have been published. paper, new methodology analyzing slope stability proposed based three...
In recent years, ground-based micro-deformation monitoring radar has attracted much attention due to its excellent capability. By controlling the repeated campaigns of antenna on a fixed track, can accomplish repeat-pass interferometry without space baseline and thus obtain high-precision deformation data large scene at one time. However, it is difficult guarantee absolute stable installation position in every campaign. If unstable, stability track will be affected randomly, resulting...
Slope collapse is one of the most severe natural disaster threats, and accurately predicting slope deformation important to avoid occurrence disaster. However, single prediction model has some problems, such as poor stability, lower accuracy data fluctuation. Obviously, it necessary establish a combination predict deformation. Here, we used GFW-Fisher optimal segmentation method multi-scale model. Our results indicated that determination coefficient linear model, weighted geometric average...
Most slope collapse accidents are indicated by certain signs before their occurrence, and unnecessary losses can be avoided predicting deformation. However, the early warning of deformation often misjudged. It is necessary to establish a method determine appropriate in sliding thresholds. Here, better understand impact different scales on thresholds, we used Fisher optimal segmentation threshold model based speed acceleration at spatial scales. Our results that accuracy thresholds surface...
